Soichi Wakatsuki is a Professor of Photon Science at the SLAC National Accelerator Laboratory where he recently initiated the Biociences Division, and Professor of Structural Biology, Stanford School of Medicine.  He received his B.S and M.S. degrees in Chemical Engineering from University of Tokyo, and his Ph.D. degree in Chemistry from Stanford University in 1991.  After postdoctoral studies on time-resolved x-ray crystallography of enzyme reactions in Oxford (1990 to 1994), he moved to Grenoble, France in 1994 to work at the European Synchrotron Radiation Facility (ESRF) where he led Joint Structural Biology Group to develop high-brilliance x-ray crystallography beamlines and instruments, as well as several structural biology projects on protein transport.  In 2000, Soichi moved back to Japan to start a new Structural Biology Research Center at KEK (High Energy Accelerator Research Organization), Tsukuba, Japan, and later served as Director of Photon Factory (national synchrotron radiation facility) from 2006 to 2012.  There he further developed x-ray beamlines and a large scale protein crystallization system, led initiatives to start three national projects on structural proteomics.  Fascinated by new research opportunities in integrative bioimaging at Stanford and the world’s first hard x-ray free electron laser (XFEL) at SLAC, Soichi returned to Stanford in 2013.  Soichi’s research interests include structural biology of post-translational modification and vesicle transport, structural biology of polyubiquitin recognition, synchrotron radiation and XFEL instrumentation, protein crystallography and small angle X-ray scattering, integrative multi-scale bioimaging.

Po-Nan Li

PhD Candidate, Electrical Engineering

My research interests is in the areas of  X-ray microscopy, laser science and computational imaging. My research now focuses on the  development of coherent X-ray imaging techniques, particularly for bioimaging applications.



Naoki Horikoshi

Visiting assistant professor, from University of Tsukuba

My research interest is to elucidate mechanisms underlying various phenomena in cells by structural, biochemical, and cell biological analyses. Now I am committed to determining the structures of protein complexes involved in cell signaling.

Hasan DeMirci

Visiting Assistant Professor

I moved from SLAC to Koc University, Turkey in September 2019. My research focuses on i) structural studies of bacterial ammonia monooxogenase (AMO) and ii) structural biology of mutant prokaryotic ribosomes, where I am interested in characterizing the function and dynamics of these mutants, with an eye toward answering questions in structure and dynamics of ribosomes which are resistant to some of today's commonly-used antibiotics. My current research efforts also  include methods development for ambient-temperature X-ray crystallography of large and challenging biomacromolecules at 4th-generation light sources like the Linac Coherent Light Source at SLAC
