Wah Chiu is the Wallenberg-Bienenstock Professor and Professor of Bioengineering and of Microbiology and Immunology at Stanford University and Director of the Division of CryoEM and Bioimaging, SLAC National Accelerator Laboratory. He earned his PhD in University of California, Berkeley. Chiu is a pioneer in methodology development for cryogenic electron microscopy (cryo-EM). His work has made multiple transformational contributions in developing single particle cryo-EM as a tool for the structural determination of molecular machines at atomic resolution. His lab has solved many cryo-EM structures including viruses, chaperonins, membrane proteins, ion channels, antigen-antibody complexes, protein-RNA complexes and RNA in collaboration with many scientists around the world. He continues to establish high standard testing and characterisation protocols for cryo-EM instrumentation and to develop new image processing and modelling algorithms for cryo-EM structure determination. His current research focuses on developing cryogenic electron tomography (cryo-ET) to determine near atomic resolution structures of molecular complexes in situ.
