Xiaoyuan Chen, Ph.D., is the Chief Investigator at the Laboratory of Molecular Imaging and Nanomedicine (LOMIN) at the National Institute of Biomedical Imaging and Bioengineering.
 He received his Bachelor of Science in 1993 and Master of Science in 1996 from Nanjing University, China.
 He then moved to the United States and obtained his Ph.D. in chemistry from the University of Idaho in 1999 under the supervision of Professor Chien M. Wai.
 After two quick postdoctoral programs at Syracuse University (under the mentorship of Dr. Jon Zubieta) and Washington University in St. Louis (supervised by Professor Michael J. Welch), Dr. Chen joined the University of Southern California as an Assistant Professor of Radiology.
 He then moved to Stanford University in 2004 to help build the Molecular Imaging Program at Stanford (MIPS) under the directorship of Professor Sanjiv Sam Gambhir, and was promoted to Associate Professor in 2008.
 In the summer of 2009, he joined the Intramural Research Program of the National Institute of Biomedical Imaging and Bioengineering (NIBIB) as a tenured Senior Investigator.
 Dr. Chen also holds a joint appointment with the NIH Clinical Center.
Wayne A. Hendrickson (born April 25, 1941, New York City) is an American biophysicist and University professor at Columbia.
 Dr. Hendrickson is a University Professor at Columbia University in the Department of Biochemistry and Molecular Biophysics and Violin Family Professor of Physiology and Cellular Biophysics.
 He is also Chief Life Scientist in the Photon Sciences Directorate at Brookhaven National Laboratory and Scientific Director of the New York Structural Biology Center.
 Hendrickson has a B.A. from the University of Wisconsin at River Falls, a Ph.D. in biophysics at Johns Hopkins University with Warner Love, and postdoctoral research experience with Jerome Karle at the Naval Research Laboratory (NRL).
 He and his colleagues use biochemistry and x-ray crystallography to study molecular properties in atomic detail with current emphasis on membrane receptors and cellular signaling, on viral proteins and HIV infection, on molecular chaperones and protein folding, and on structural genomics of membrane proteins.
 Hendrickson's advances in diffraction methodology have contributed significantly to the emergence of structural biology as a major force in modern biology and molecular medicine.
B. Montgomery "Monte" Pettitt is the Director of the Sealy Center for Structural Biology and Molecular Biophysics at University of Texas Medical Branch (UTMB) in Galveston, Texas, holder of the Robert A. Welch Distinguished Chair in Chemistry, and tenured Professor in the Department of Biochemistry and Molecular Biology, as well as the department of Pharmacology and Toxicology at UTMB.
 He is also affiliated with and former director of the The W. M. Keck Center at Rice University, and a faculty member of the Structural and Computational Biology and Molecular Biophysics (SCBMB) program at Baylor College of Medicine.
 At the University of Houston, he was the Hugh Roy and Lille Cranz Cullen Distinguished Professor of Chemistry and Robert A. Welch Chair in Chemistry, as well as the director of its Institute for Molecular Design.
Axel T. Brunger (born November 25, 1956) is a German American biophysicist.
 He is Professor of Molecular and Cellular Physiology, and Neurology, of Photon Science and, by courtesy, of Structural Biology at Stanford University, and a Howard Hughes Medical Institute Investigator.
 He also is currently serving as the Chair of the Department of Molecular and Cellular Physiology (2013–present).
Valerie Daggett is a professor of bioengineering at the University of Washington in Seattle, Washington, United States.
 She received her Ph.D. from the University of California, San Francisco, advised by Irwin Kuntz and Peter Kollman, and subsequently held a postdoctoral position at Stanford University with Michael Levitt, a co-recipient of the 2013 Nobel Prize in Chemistry.
K. Christopher "Chris" Garcia, Ph.D., is an American scientist renowned for his research on the molecular biology of cell surface receptors.
 Garcia is a Professor in the Departments of Molecular and Cellular Physiology and Structural Biology at the Stanford University School of Medicine, an Investigator of the Howard Hughes Medical Institute and a member of the National Academies of Science and Medicine.
 In addition to his role at Stanford, Garcia is a co-founder and board member of several biotechnology companies including Eleven Biotherapeutics, Alexo Therapeutics and Surrozen.
Michael Levitt, FRS (Hebrew: מיכאל לויט‎ ‎ ; born 9 May 1947) is an American-British-Israeli biophysicist and a professor of structural biology at Stanford University, a position he has held since 1987.
 Levitt received the 2013 Nobel Prize in Chemistry, together with Martin Karplus and Arieh Warshel, for "the development of multiscale models for complex chemical systems".
Geoffrey Chang is a professor at the University of California, San Diego's Skaggs School of Pharmacy and Pharmaceutical Sciences and Department of Pharmacology, School of Medicine.
 His laboratory focuses on the structural biology of integral membrane proteins, particularly exploring X-ray crystallography techniques for solving the tertiary structures of membrane proteins that are notoriously resistant to crystallization.
 The laboratory has specialized in structures of multidrug resistance transporter proteins in bacteria.
 In 2001, while a faculty member of The Scripps Research Institute, Chang was awarded a Beckman Young Investigators Award, designed to support researchers early in their academic careers, for his work on the structural biology of multidrug resistance.
 Chang announced a move from Scripps to neighboring UC San Diego in 2012.
Stephen Ronald Quake (born 1969) is an American scientist, inventor and entrepreneur.
 He earned his B.S. in Physics and M.S. in Mathematics from Stanford in 1991 and his D.Phil.
 in Physics from Oxford University in 1994 as a Marshall Scholar.
 His thesis research was in statistical mechanics and the effects of knots on polymers.
 He did his postdoctoral work at Stanford in single molecule biophysics with Steven Chu.
 Quake joined the faculty of the California Institute of Technology at the age of 26, where he rose through the ranks and was ultimately appointed the Thomas and Doris Everhart Professor of Applied Physics and Physics.
 He moved back to Stanford University in 2005 to help launch a new department in Bioengineering, where he is now the Lee Otterson Professor of Bioengineering and Applied Physics, and an Investigator of the Howard Hughes Medical Institute.
John C. Mitchell is the Vice Provost for Teaching and Learning at Stanford University, the Mary and Gordon Crary Family Professor in Computer Science and Electrical Engineering at Stanford University, co-director of the Stanford Computer Security Lab, and Professor (by courtesy) of Education.
 He is a member of the steering committee for Stanford University's Cyber Initiative.
 Mitchell has been Vice Provost at Stanford University since 2012, first as the inaugural Vice Provost for Online Learning and now in a broader role for Teaching and Learning.
 Under Mitchell's direction, the Office of the Vice Provost for Teaching and Learning (VPTL) is advancing teaching and learning through faculty-driven initiatives and research, transforming education in Stanford's classrooms and beyond.
