Fellows of the American Crystallographic Association

Class of 2020
Thank you to ACA Member Kay Onan for the following summaries.

Carol P. Brock, Professor Emerita of Chemistry at the University of Kentucky, is one of the world’s experts on the systematics of packing of molecular crystals. Her interest is in the whys of crystal packing; indeed, her work with Jack Dunitz resulted in a series of influential publications culminating in one entitled “Towards a Grammar of Crystal Packing.”

Besides understanding the systematics of packing in molecular crystals, Carol’s scientific interests include pseudosymmetry and phase transitions in molecular crystals. Her detailed analyses of phase transitions of two nickel complexes, published in 2011 and 2012, have been said to set the standard of how serious phase transition studies should be carried out.

Her work has sometimes used the data from the Cambridge Structural Database to help elucidate the mysteries of high Z’ structures (those with more than one molecule in the asymmetric unit) and the forces uniting symmetry, crystal packing, and pseudosymmetry. For instance, in a 2016 paper, she examined 284 structures with Z’ > 4 to study approximate translations in structures of molecular crystals. Recently, working with Robin Taylor, she has examined 181 kryptoracemates, which are racemic crystals in which the enantiomers are crystallographically independent, to help understand the approximate symmetry in space group P1 with Z’ > 1.

All of Carol’s work is thorough, incredibly meticulous and insightful.

Carol is a strong proponent of crystallography within the broader chemical community and her service to the American Crystallographic Association (ACA) and the International Union of Crystallography (IUCr) has been extensive and exemplary. It began in 1977 when she served as Chair of the Public Information Committee. She has since participated in, and chaired, numerous ACA committees as well as serving as an officer of the U.S. National Committee on Crystallography (USNC/Cr). She has been a member of several IUCr Commissions, her most longstanding being on the Commission on Journals; over time she was Co-Editor or Editor of Sections A, B and C of Acta Crystallographica. Notably, she is the Editor-in-Chief of the International Tables for Crystallography.

Carol is a scientist with excellent research, abundant service and thoughtful approaches to crystallographic education.

Stephen K. Burley, University Professor and Henry Rutgers Chair at Rutgers and Director of the RCSB Protein Data Bank, is a brilliant crystallographer, scientist and physician with very broad accomplishments. He is an expert in structural biology, proteomics, bioinformatics, structure/fragment based drug discovery and clinical medicine/oncology. Throughout his research Stephen has shown a great deal of wisdom and creativity in choosing and designing systems for structural studies.

Stephen has made fundamental and broad contributions to the understanding of transcription initiation in higher organisms, the process by which a cell starts the synthesis of an RNA copy of genetic information in DNA. While at Rockefeller University, he determined a series of high-resolution crystal structures of the key general transcription factors that mediate transcription initiation. He also determined high-resolution crystal structures of several of the most important specific transcriptional regulatory factors that “turn up” and “turn down” RNA synthesis - at different genes and in different cell types, developmental states and environmental conditions - and their complexes with DNA. With this work Stephen essentially founded the field of structural studies of transcription initiation in higher organisms.

Stephen also made critical contributions to the understanding of how proteins are translated from mRNA on ribosomes. With this work, he pioneered the application of combining limited proteolysis and mass spectroscopic techniques to identify constructs for successful crystallization.

Stephen’s productivity as a structural biologist has been nothing short of incredible; his 1238 PDB depositions represent nearly 1% of the total. His publications have been cited more than 40,000 times.

In addition to his accomplishments in academia, Stephen has been active in the private sector with a number of biotech companies as a founder, board member, and consultant.

He has been active in the ACA having served, for example, as chair of the Industrial and Synchrotron Special Interest Groups, as an ACA Transactions Symposium co-organizer and as a member of the Data. Standards and Computing Committee. His farthest-reaching contribution to the worldwide crystallographic community, though, is undoubtedly the service he has provided by taking on the Directorship of the RCSB Protein Data Bank upon Helen Berman’s retirement.


Larry R. Falvello, Professor of Inorganic Chemistry at the University of Zaragoza, Spain, has been a key player in crystallography since this technique became essential in the resurgence of inorganic chemistry and the development of organometallic chemistry. His research program involves the synthesis of novel coordination compounds and studies of their dynamics and physical properties. All of the research is backed by crystallographic studies of the very highest standard and has involved high quality studies of phase transitions and proton-hopping in the stolid state. His contributions are extremely well-executed and presented in complete detail written so both experts and non-experts can understand and appreciate the work. This is a characteristic of all Larry’s work: He is, at heart, an educator. An outstanding early example of his phase transition studies is of a nickel complex that transforms from Fmmm at room temperature (RT) to Cmcm at lower temperatures; the molecular shape changes noticeably and reversibly from RT to 140K and then by lesser amounts from 140K down to 11K. Both X-ray and neutron diffraction, as well as electronic spectroscopy and studies of the magnetic properties presented an excellent and complete analysis of the process.

In his career Larry has trained hundreds of next-generation crystallographers. He spent 10 years working with F. A. Cotton who, in his memoir, states “During the time he (Larry) was with me I lost all remaining capacity to supervise X-ray crystallographic work in a hands-on way. … Of course, with Larry in charge I had no need to worry about details and technicalities anymore, so I didn’t try. Larry was a wonderful teacher and taught everyone …” Larry’s independent career began at the University of Zaragoza. Here, besides teaching inorganic chemistry courses, he teaches short courses and modules on crystallography. At other institutions he has taught short and full-scale courses on single-crystal and powder X-ray and neutron diffraction and has led workshops on diffraction methods and specific techniques. He was recently the recipient of the Gold Medal for Distinguished Service in the Development of the Doctoral Program awarded by the Slovakian Faculty of Science of the Pavol Jozef Safarik University in Kosice.

His service to the crystallographic community has been exceptional. The fact that Larry travels to ACA meetings from Spain illustrates his commitment to the organization and its value. He has organized 17 sessions for ACA meetings and they are always well-attended. He has served the IUCr and crystallographic community as the Main Editor for Acta Cryst., Section C, as Editorial Advisory Board member for Section E, and as a member of the IUCr Commission on Publications and CIF Dictionary Management Group. As editor, Larry also shows his love of, and skill in, mentoring; he is kind and patient with authors and shows a willingness to assist them with their efforts, especially for the young and inexperienced.

Larry is a skillful and distinguished researcher who has been an extraordinary mentor to generations of young crystallographers and who has served the crystallographic community enthusiastically and well.

Bruce M. Foxman, Professor Emeritus of Chemistry, Brandeis University, is widely recognized as a leader of the solid-state chemistry research community for his work spanning broad areas including topotactic relationships, solid-state polymerization, and polymorphism, among many others. The breadth of his interests and the depth of his insights distinguish Bruce’s work. His expertise in the areas of phase transformations, solid-state photochemistry, energetic materials, and x-ray crystallography have led to many well-cited publications. These papers display deep understanding and provide weighty, thoughtful contributions to the science community.

Over a tenure spanning more than 45 years at Brandeis University, in addition to directing a renowned research program and collaborating with other distinguished Brandeis colleagues, Bruce oversaw a busy X-ray structure determination service. Bruce’s research on chemical systems is complemented by his contributions to the development of methodology. In recent years he has written two new programs addressing frontier issues in crystallography; one to derive topotactic relationships between beginning and ending phases in a phase transition and another to calculate twin laws. Both of these programs are freely available on this website. He is also well-known for having contributed ideas and code to the Crystals software package.

At his core, Bruce is an educator. He is a superb lecturer (which earned him an Excellence in Teaching award from Brandeis) whose reputation transcends the University. He has been a lecturer at several specialized schools and, in addition, has developed well-received on-line tutorials on various aspects of crystallography. Co-authored with Jerry Jasinski, the “Symmetry and Space Group Tutorial” has been downloaded some 6000 times. His status as an educator and his interest in education can be seen in his membership on the College Board’s Advanced Placement Chemistry Committee. He worked on this Committee through the 1990s, serving as Chair for one term. Bruce is known for his nurturing of the next generation of scientists. He is committed to his students’ success and acts as a mentor and advocate for junior scientists. He taught at three Crystallography Summer School and always spent time mentoring students in a one-on-one manner.

The service he has proved to the ACA and to the broader chemical community is significant. Bruce has served on multiple advisory committees for internationally recognized scientific journals and organizations. Bruce has been a member of the ACA for 54 years (!) and has been a session speaker or organizer with regularity, e.g., in 2016, Bruce was a Co-Chair of the High-Impact Crystallographic Education Session at the Denver ACA meeting. In 2012, he took on the role of Co-Chair of the Boston ACA meeting.

Bruce is a superb teacher, an influential crystallographer, and a remarkable scholar who is well known to give generously of his time to those around him and to the scientific community.  


Marvin L. Hackert, William Shive Centennial Professor in Biochemistry at the University of Texas at Austin, is known for his studies on the characterization, mechanism of action and structures of proteins and their complexes using the tools of protein crystallography, protein engineering and mutagenesis. Of particular note are his activities in combining protein structures with small-molecule design and analysis in order to develop novel inhibitors to several enzyme families. One research focus was on members of the 4-oxalocrotonate tautomerase (4-OT) “superfamily” of proteins. The Hackert lab crystallized and solved about 20 crystal structure from 11 different members within this family, including at least one representative member from each of the five major sub-families they had identified for the smaller members of the superfamily.

Another research focus was the regulation of polyamine biosynthesis by studying the regulation of ornithine decarboxylase (ODC) which initiates this biosynthesis. Antizyme (AZ) reduces the cellular polyamine content by down-regulating both the enzyme catalyzing polyamine biosynthesis, ODC, and the uptake of polyamines. The activity of AZ is repressed by the binding of a protein named antizyme inhibitor (AZI), which is an enzymatically inactive homologue of ODC. Hackert’s lab solved the X-ray structure of ODC and collaboration with David Hoffman revealed the NMR structure of antizyme. This is a step in understanding the structure/function relationship in this system.

For the past several years Marv has focused on administration of various sorts. He has served as Associate Dean of the Graduate School for the past 14 years. In this leadership role he has the ability to nurture young scientists. In support of this he won a five-year, NSF Graduate Research Fellowship grant of nearly $19 million.

Marv has been active in serving the international crystallographic community. He was President of the IUCr from 2014-2017 and has served on the Executive Committee of the IUCr from 2010 through 2020. During this time he worked on many projects including organizing the International Year of Crystallography for the IUCr. This work culminated in his presiding over the IYCr closing ceremony in Rabat, Morocco. He also worked on promoting Building Science Capacity in Africa via Crystallography. He has served on the US National Committee for Crystallography for nearly 20 year, chairing it from 1999 – 2002, and as a member of the Board on International Scientific Organizations since 2011. Marv has always served the ACA; In 1992 he was awarded the American Crystallographic Association Service Award. In 2008 Marv showed his leadership skills by assuming the role of President of the American Crystallographic Association.

Marv has shown his leadership in the crystallographic and scientific communities both through his excellent work in structural enzymology and his admirable administrative skills. He has had an impact on many science students’ careers through the mentoring of his own students and through the mentorship and resources he provides to graduate students in his leadership role in the UT Austin Graduate School.

James A. Kaduk, President of Poly Crystallography, Inc., is a world-class expert at performing structural refinement using the powder diffraction technique, particularly with GSAS. He was one of the first to show that combining crystallographic investigations with quantum mechanical theory allows for much greater levels of structural information to be determined, such as validation of H atom sites. He is a recognized leader in the materials research field and is internationally known for his work in catalysts, ceramics and pharmaceuticals materials research. His technical accomplishments are top-notch. His deep knowledge of crystallography means that he is not only at home in the world of chemical crystallography and materials sciences but has also taught at the ACA Summer Course on Macromolecular Crystallography for several years and is a world expert on synchrotron diffraction. He has been involved in proposal review panels at the Advanced Photon Source at Argonne National laboratory, the Oak Ridge National Laboratory and at the National Synchrotron Light Source at Brookhaven National Laboratory.

Jim is a Distinguished Fellow of the ICDD and, at the 2017 Denver X-ray Conference (DXC), was awarded the Jenkins Award for lifetime achievement in the advancement of the use of X-rays in material analysis.

Sharing his knowledge is important to Jim. He has taught in the ACA Summer Course in Small Molecule Crystallography since 2004 and at workshops at the DXC and other meetings around the world. He was a faculty member at ICDD’s Advanced X-ray Diffraction Clinic and at the Short Course on the Rietveld Method and Indexing. He is currently a Research Professor at the Illinois Institute of Technology and a Senior Research Scientist at North Central College. Since 2007 Jim has been a co-editor for Crystallography Education of the journal Powder Diffraction.

In service to the crystallographic community, Jim has assumed many important responsibilities in various crystallographic organizations. His work with the ACA has included taking on officer roles and serving on an array of committee. He has had a profound influence on the well-being and expansion of ICDD. He has held many and varied leadership roles in this organization including serving as Chair of the New Product R&D Subcommittee, Chair of the Sales and Marketing Subcommittee, Chair of the PDF Database Subcommittee and Chair of the Membership Committee. Perhaps most notably, he served as the Chair of the Board of Directors for two terms.

Jim has served nationally as the Chair of the US National Committee on Crystallography and has provided extensive international service by taking on many co-editor and committee roles in the International Union of Crystallographers. In particular, as one of three co-editors of the International Tables for Crystallography, Volume H, Jim has spent a significant amount of time ensuring the quality and the usefulness of the volume to the powder diffraction community.

Jim is recognized for his exceptional contributions in advancing the field of structural science, particularly powder diffraction. He a remarkable scientist, an outstanding educator, an efficient scientific administrator and a keen scientific editor.

Lisa J. Keefe, Director of the Industrial Macromolecular Crystallography Association – Collaborative Access Team (IMCA – CAT) at the Advanced Photon Source (APS) and Vice President for Advancing Therapeutics at Hauptman-Woodward Medical Research Institute, has spearheaded the continuous improvement of IMCA – CAT into, arguably, the world’s premier industrial protein crystallography beamline. Her group has an average time between receiving crystals to producing diffraction data of one day for well over 90% of samples. Their beamline collects up to 300 structural datasets a day and the number of industrial users is growing. This facility has been critical to advancing the drug discovery research at both member and non-member companies.

Lisa has shown operational and business acumen in her management of the beamline. For instance, she negotiated the purchase of a new IMCA detector and managed its installation so that it became fully operational without interrupting normal workflow. Another example involves a bending magnet beamline that had fallen into disuse. Lisa had the creative idea of leasing that beamline back to the APS as a test bed bringing income to IMCA from what had been a burden.

The APS is down a few weeks a year for maintenance, upgrades and the like and these interruptions work a hardship on the industrial members. Lisa has established reciprocal beamline agreements to allow remote data collection at other sites, including at the Canadian Light Source, to provide year-round data collection for users.

Lisa is a strong advocate for macromolecular crystallography and science in general. She hosts visits from various state and federal government agencies, promotes letter-writing campaigns regarding the importance of consistent and adequate scientific funding, and supports symposia and sessions at the annual ACA meeting that allow industrial crystallographers an opportunity to showcase how structural biology contributions further target-based drug discovery.

Lisa is a strong supporter of the ACA and has served it in two major leadership roles. The high regard in which her colleagues hold her resulted in her serving as President of the ACA and subsequently she was appointed as Interim CEO of the ACA.

Amy A. Sarjeant, Principal Scientist at Bristol-Myers Squibb Company, has demonstrated excellence in all aspects of her multifaceted professional career. Her trajectory has taken her to industry and academia and back to industry; she has worked in sales, service, management and education.

One of the ways that Amy’s crystallographic expertise has been recognized is by being named as a co-editor for Acta Cryst. C. Some of her notable collaborative scientific efforts include the following: Working with Sir J. Fraser Stoddart at Northwestern, she contributed structure solutions and interpretations that were essential for understanding the design and function of molecular machines and which helped advance work in this field. While working at the Cambridge Crystallographic Data Centre (CCDC), Amy was part of a team that undertook the capture of neon in a metal-organic framework. The structure was solved by using in-situ synchrotron powder X-ray diffraction and represents the first report of a single crystal structure that contains neon, the fifth most abundant element in our galaxy.

The commitment that Amy shows for teaching the next generation of structural scientists shows throughout her career. She was one of three organizers of the ACA Summer School for Small Molecule Crystallography from 2012 to 2019 and also taught in the analogous Canadian Chemical Crystallography Workshop. Her leadership in these endeavors led to her position as Education and Outreach Manager at CCDC. In this role she taught many crystallographers the power of database mining. She is international in her reach having taught crystallography in Ghana, in New Zealand, in Botswana, Japan and Mexico.

Amy is a staunch supporter of the ACA and has assumed many leadership roles – as a Program chair, in sessions, in SIGs and, in 2017, as President of the organization. This was a challenging time for the ACA and Amy proved to be a voice of reason and a hard-working and creative leader who put the organization back on solid footing.

Amy has been tireless in her commitment to the ACA, to professional development for all our members across all career stages, and to the discipline. She is a strong proponent of the next-generation of scientists and, importantly, to women and minorities in STEM.

Hao Wu, Asa and Patricia Springer Professor at Boston Children’s Hospital and Harvard Medical School, is a world leader in structural immunology whose work has rewritten the conventional view of signal transduction for immune signaling. Her results implicate new mechanisms of intracellular signaling and cellular organization more generally. She has crystallographically determined structures for many critical signaling complexes and has discovered and characterized several very large, oligomeric “signalosomes” that assemble in response to engagement of innate immune receptors. These signalosomes are a higher order assembly that brings ligands, receptors, adaptor proteins, signaling enzymes and their protein substrates into a gigantic oligomeric complex that lacks a fixed stoichiometry and can form polymeric complexes of different sizes. To study these and related complexes, she has extended her studies to cryo-electron microscopy analysis, a technique in which she has become an expert.

Recently Hao has demonstrated the significance of higher-order signaling by investigating “inflammasomes” which are cytosolic supramolecular complexes that detect and respond to stimuli from pathogens and other dangers.

Hao has received a number of honors and awards. She is a Pew Scholar, a Rita Allen Scholar, a Fellow of the American Association for the Advancement of Science, a Fellow of the Biophysical Society and, significantly, a member of the National Academy of Sciences. She is a recipient of NIH MERIT and Pioneer awards, the Margaret Oakley Dayhoff Award (Biophysical Society), the Dorothy Crowfoot Hodgkin Award (Protein Society) and the Milstein Award (International Cytokine & Interferon Society).

In addition to her highly successful research program, Hao is a conscientious member of the structural biology community. She has mentored numerous students and postdocs. She serves on the scientific advisory committees of various X-ray beamlines at the National Synchrotron Light Source II and the Advanced Photon Source. She teaches X-ray crystallography at her home institutions and has presented crystallography-for-kids on a local National Public Radio station and in local schools. She has been a frequently invited speaker at ACA meetings and has organized several other conferences. She served on the temporary nominating group of the National Academy of Sciences to stimulate the election of under-represented, especially-qualified women scientists.

Hao is an exceptionally creative scientist who combines brilliance and imagination; she is defining and then solving the key problems in the structural biology of innate immune signaling.

Victor G. Young, Jr., Director of the X-Ray Crystallography Laboratory, University of Minnesota, is well- known for his deep knowledge of, and excellent work on, twinned crystal structure determination. Victor carried out his Ph.D. work with Robert Sanner and Robert Von Dreele at Arizona State University and stayed there to do postdoctoral work with Bill Glalusinger. In this position he proposed and conducted neutron scattering research at both Los Alamos National Laboratory and Argonne national Laboratory. This work led to a two-year Visiting Scientist position with Jack Conant at Los Alamos National Laboratory where he modernized a neutron powder diffractometer. He took a position at Iowa State University as Staff Crystallographer, moving to Minnesota in 1995. Early in his time at Minnesota, he was involved with the development of the micro-diffractometer at the ChemNatCars beamline which positioned him well for studies of very small crystals and, more recently, for resonant diffraction studies.

The first twinned area detector data set Victor collected was in 1996. From then on, until Bob’s untimely death, he collaborated with Robert Sparks on twinning. Victor’s development work on the early 2D detectors was vital to allowing many types of twinned data sets to be collected and analyzed. He has continued in this work and is a co-author of the Twin CIF Dictionary 1.0, targeted for inclusion in the next edition of Volume G of the International Tables for Crystallography.

Victor has given noteworthy service to the ACA and to the wider world of crystallography via the US National Committee in Crystallography (USNC/Cr). He has twice served as a USNC/Cr delegate to IUCr meetings. He has attended every ACA meeting since 1991, chaired many of its sessions and was local committee co-chair at the 2000 ACA meeting. Through his participation on the ACA Nominations Committee, which he chaired in 2015, he has persuaded many also to serve the ACA. Through his teaching at several ACA Summer Schools, he has helped prepare the next generation of crystallographers.

Victor’s development of, and publications in, the field of twinning of single crystal specimens have been stellar. His early work in twinned crystals was critical to the software and hardware development associated with the early 2D detectors and allowed the community to solve an unprecedented number and variety of twinned data sets. His years of exceptional contributions have been a great benefit to the ACA.

Guidelines for Selecting ACA Fellows

As of August 8, 2013. REVISED 05/25/14 / REVISED 8/2019

The ACA Council has established a Fellows program. It serves to recognize a high level of excellence in scientific research, teaching, and professional duties, but also service, leadership, and personal engagement in the ACA and the broader world of crystallography and science. Our Fellows program celebrates the excellence of our own members from within the ACA and promotes their recognition worldwide to constituencies outside of the ACA, such as their employers, other scientific societies, and the government. ACA Fellows serve as scientific ambassadors to the broader scientific community and the general public to advance science education, research, knowledge, interaction, and collaboration. This program allows us to significantly recognize and honor a broader cross-section of the membership than was previously possible with other, more specific awards. We envision that eventually about 5% of the membership will be recognized as Fellows, and the ACA will announce new inductees and honor all ACA Fellows at the annual Awards Banquet.


A Fellow is defined as "a Member whose efforts on behalf of the advancement of crystallography or its applications that are scientifically or socially distinguished." Examples of areas in which nominees may have made significant contributions are research; teaching; technology; services to professional societies; administration in academia, industry, and government; and communicating and interpreting science to the public. Fellows are elected annually by the current group of Fellows.


The procedure for nominating and selecting Fellows is as follows:

  • Candidates for ACA Fellow must be a current ACA member, meaning that the candidate must have paid ACA dues for the year they are nominated.
  • A nomination package must be completed by the nominator, who must also be an current ACA member. In a cover letter, a case should be made for how the proposed Fellow meets the above criteria. A brief CV must also be provided, as well as two letters from at least other current ACA members supporting the nomination.
  • Nominations are due each year by April 1st . All nominations will be collected at ACA Headquarters and distributed to the current Fellows for review. A score sheet shall be provided.
  • Nominations for ACA Fellows shall roll over twice, without any additional submissions from the nominator (i.e., candidates for Fellow who are nominated but not elected in one year will be automatically reviewed during each of the following two years), provided that the candidate remains as current ACA.
  • Current Fellows shall provide a yes/no/abstain vote on each nominee. Fellows will submit their recommendations to ACA Headquarters within 3 weeks of receipt of the nomination packet. For a candidate to be approved as a Fellow, greater than 50% of the votes actually cast for that candidate must be “yes,” AND the number of yes votes must be greater than or equal to 25% of the total number of current Fellows. An abstention does not count as a vote.
