James was an undergraduate at McGill University, where he worked in the lab of Francois Fagotto on Xenopus developmental biology. During the summers, he returned to his hometown of Toronto and worked in Alan Davidson’s lab on TetR repressor biophysics and bacteriophage genomics.
He moved to California in 2005 to do his Ph.D. in Molecular and Cellular Biology at UC Berkeley. There, he worked with Tom Alber creating biophysical methods to characterize protein side chain flexibility in high resolution X-ray electron density maps. They applied these techniques to study connections between conformational dynamics and enzymatic catalysis, showing that room temperature, but not standard cryogenic, X-ray data collection could reveal the structural basis for critical functional motions.
Near the end of his Ph.D., he was an EMBO Short-Term Fellow in Dan Tawfiks lab. Concurrently, he authored the problems and solutions manual for the physical chemistry textbook The Molecules of Life by Kuriyan, Konforti, and Wemmer.
In January 2011, James started his independent career as a QB3 at UCSF Fellow affiliated with the Department of Cellular and Molecular Pharmacology. In January 2013, he was appointed as an Assistant Professor in the Department of Bioengineering and Therapeutic Sciences and the California Institute for Quantitative Biosciences (QB3) with promotion to Associate Professor in 2016, and Full Professor in 2020. The lab is also part of the Macromolecular Structure Group at UCSF and BioXFEL, a Science and Technology Center established by the National Science Foundation. We maintain a deep connection with Beamline 8.3.1., directed by James Holton, at the Advanced Light Source. James is also a Faculty Scientist in the Molecular Biophysics and Integrated Bioimaging Division of Lawrence Berkeley National Lab. James is the Associate Director of the Biophysics Graduate Program.
In addition to all the exciting developments in the lab, James is on the board of ASAPbio and has a long standing interest in teaching computational biology, baseball statistics, and project-based courses. The lab is committed to publishing our code, disseminating our datasets, and posting manuscripts on preprint servers. His full conflicts of interest are available here.

He earned his Ph.D. in chemistry from UC Berkeley working with Drs. Junko Yano, Vittal Yachandra and Nick Sauter at Lawrence Berkeley National Laboratory on discovery of the mechanism of water splitting in oxygenic photosynthesis using X-ray free electron laser (XFEL) diffraction. He worked with the Sauter group to develop XFEL diffraction data processing methods, including the cctbx.xfel program for real-time feedback at XFEL experiments, and with the Yano/Yachandra group to solve several of the first high-resolution room temperature structures and the first high-resolution transient state structures of photosystem II, revealing the sequence of changes at the heterometallic cluster that catalyzes oxygen evolution. As a postdoc with the Fraser group, he is collaborating with the developers of the cisTEM software for macromolecular structure determination by cryo-electron microscopy to improve recovery of flexible molecular motions with this technique. This project aims to determine the mechanism of transcript-dependent but sequence-independent translational efficiency of a pool of naturally occurring, compositionally and conformationally heterogeneous ribosomes, with implications for regulation of the proteome at the stage of translation.
