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.

Eric is interested in understanding how protein conformations impact function and regulation, and, how posttranslational factors that occur throughout a protein’s lifetime further tune function. Eric graduated from the University of Colorado, Boulder with degrees in Biochemistry and Molecular, Cellular, and Development Biology. As an undergraduate, he worked with Zhongping Tan using chemical biology approaches to study glycosylated proteins. As a graduate student in Andy Martin’s lab at UC Berkeley, Eric studied how conformations and conformational dynamics of the 26S proteasome influence degradation processes. He also collaborated with Susan Marqusee’s lab to help illuminate how energetic changes conferred by site-specific ubiquitination on substrate proteins influenced whether, and how, these proteins were degraded by the proteasome.
In the Fraser lab, Eric seeks to understand how protein conformational states influence activity and regulation of metabolic enzymes. When not in the lab, Eric enjoys spending time at home with his cats, running, skiing, mountain biking, and cooking.
Daniel graduated from Stanford, where he worked on single-molecule biophysics with Steven Block.
He joined the Fraser lab in 2020, where he works to improve and expand their computational resources. He’s passionate about open science, open data, and open-source software. Outside of lab, he can usually be found running or playing board games.
John earned his Ph.D. working with Dr. Michael Burkart at the University of California, San Diego. His primary focus was the application of protein NMR to the carrier proteins central to fatty acid, polyketide, and non-ribosomal peptide synthetic pathways.
In the Fraser lab, he will use structural and computational techniques to explore structural biology and study minor conformational states.
John is supported by a Kirschstein NRSA (F32) fellowship from NIH/NIAID.
Jen completed her undergraduate degree at Boston University in Biochemistry and Molecular Biology where she studied neurobiology of female rat reproduction under Dr. Mary Erskine. She went on to work as a lab supervisor and in the algae biofuels industry before returning to academia to pursue her Ph.D. at UC San Diego in the lab of Dr. Michael Burkart. In his lab she worked on diverse projects ranging from the use of biochemical probes to understand protein-protein interactions in fatty acid and polyketide synthases to various approaches including metagenomics to explore the biochemical influences on marine atmospheric composition.
In the Fraser lab she seeks to utilize computational approaches to enable high-throughput experiments through automation and pipeline development.

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 Alexis Rohou at Genentech to expand on the cisTEM software for macromolecular structure determination by cryo-electron microscopy. This project aims to improve the quality of reconstructions from particularly difficult datasets, both by reducing overfitting artifacts and by embedding parameters for particle flexibility into the maps themselves. He is also working on tools built on the Computational Crystallographic Toolbox (ccbtx) to detect unmodeled features in electron density such as post-transcriptional modifications (qPTxM) or Hoogsteen base pairs (curiosity). During the COVID-19 pandemic he has served as co-lead of the crystallography subgroup of the Structural Biology Consortium, associated with the QBI Coronavirus Research Group at UCSF, pursuing the discovery of compounds inhibiting SARS-CoV-2 infection.
Outside of lab, Iris enjoys reading, sewing, throwing pottery, and learning languages. He measures his coffee intake in LD50s.
Iris is supported by a Kirschstein NRSA (F32) fellowship from NIH/NIGMS.
Willow graduated from the Evergreen State College with degrees in Chemistry and Environmental studies. As an undergraduate in Anitra Ingalls’ lab at the University of Washington, he studied how B vitamins mediate microbial interactions and diversity in the open ocean. For graduate school, Willow did his PhD in Daniel Schmidt’s lab at the University of Minnesota, where he developed massively parallel sequencing-based methods to study and engineer proteins. Using mutational and insertional scanning methods, Willow found these methods can be useful for identifying regions of a protein involved in functionally meaningful conformational changes, developed mechanistic models for how to assemble protein domains to create useful multi-domain protein tools, and studied the evolution of ion channel regulation.
As an HHMI Hanna Gray and QBI Fellow, Willow is inventing high-throughput sequencing-based biophysics and biochemistry methods for understanding how a genetic, chemical, or physical perturbations alters the trafficking or functional state of receptors. The long-term goal of this work is to build mechanistic holistic models of how receptors break in disease and work in normal physiology
