Stephen M. Hinshaw
Assistant Professor (Research) of Molecular and Cellular Physiology
BioStephen Hinshaw is an Assistant Professor in the Department of Molecular and Cellular Physiology and the Faculty co-Director of the Stanford Cryo-Electron Microscopy Center (cEMc). His laboratory develops and applies cutting-edge tools in chemical and structural biology to uncover fundamental cellular mechanisms and translate these insights into powerful new pharmacological strategies.
Stephen received his undergraduate degree from Stanford University and earned his Ph.D. from the Harvard Program in Genetics and Genomics, where he discovered fundamental mechanisms governing chromosome segregation during mitosis. He then conducted postdoctoral research as a Helen Hay Whitney Fellow supported by the Howard Hughes Medical Institute at Harvard Medical School, with additional training as a visiting postdoctoral fellow at the Janelia Research Campus. During this period, he used cryo-electron microscopy to determine the structures of protein complexes that underlie genetic inheritance in normal and cancer cells. Prior to joining the Stanford faculty, Stephen led discovery efforts for new therapeutic modalities as a Senior Research Scientist in the Center for Therapeutics Discovery and at the Stanford Cancer Institute. -
Karen G. Hirsch, MD
Professor of Neurology and Neurological Sciences (Adult Neurology)
Current Research and Scholarly InterestsDr. Karen G. Hirsch cares for critically ill patients with neurologic disorders in the intensive care unit. Dr. Hirsch's research focuses on using continuous and discrete multi-modal data to develop phenotypes and identify signatures of treatment responsiveness in patients with coma after cardiac arrest. She is the Co-PI of PRECICECAP (PRecision Care In Cardiac ArrEst - ICECAP, NINDS R01 NS119825-01). The research team works closely with collaborators in data science at Stanford and with industry partners to apply machine learning analyses to complex multi-modal ICU data. Dr. Hirsch also studies neuro-imaging in post-cardiac arrest coma and traumatic brain injury, and with colleagues in Cardiac Anesthesia and Cardiothoracic Surgery, Dr. Hirsch studies neurologic outcomes in patients on mechanical circulatory support including ECMO.
Along with colleagues in Biomedical Ethics, Dr. Hirsch studies brain death, organ donation, and neuroethics. She is the Co-PI of BCI-DEF (Brain Computer Interfaces and Disability: Developing an Inclusive Ethical Framework, NIMH 1R01MH130518-01) which is a BRAIN Initiative funded study that is qualitatively evaluating end user perspectives about the benefits, risks, and ethical challenges of Brain Computer Interfaces for patients with acute stroke or traumatic brain injury.
Dr. Hirsch is broadly interested in improving neurologic outcomes after acute severe brain injury, identifying early phenotypes to guide precision medicine in neurocritical care, and exploring ethical issues in neurocritical care and novel neurotechnology. Dr. Hirsch greatly appreciates the importance of team science and collaboration. -

Keith Hodgson
David Mulvane Ehrsam and Edward Curtis Franklin Professor of Chemistry and Professor of Photon Science
On Leave from 10/01/2025 To 03/31/2026BioCombining inorganic, biophysical and structural chemistry, Professor Keith Hodgson investigates how structure at molecular and macromolecular levels relates to function. Studies in the Hodgson lab have pioneered the use of synchrotron x-radiation to probe the electronic and structural environment of biomolecules. Recent efforts focus on the applications of x-ray diffraction, scattering and absorption spectroscopy to examine metalloproteins that are important in Earth’s biosphere, such as those that convert nitrogen to ammonia or methane to methanol.
Keith O. Hodgson was born in Virginia in 1947. He studied chemistry at the University of Virginia (B.S. 1969) and University of California, Berkeley (Ph.D. 1972), with a postdoctoral year at the ETH in Zurich. He joined the Stanford Chemistry Department faculty in 1973, starting up a program of fundamental research into the use of x-rays to study chemical and biological structure that made use of the unique capabilities of the Stanford Synchrotron Radiation Lightsource (SSRL). His lab carried out pioneering x-ray absorption and x-ray crystallographic studies of proteins, laying the foundation for a new field now in broad use worldwide. In the early eighties, he began development of one of the world's first synchrotron-based structural molecular biology research and user programs, centered at SSRL. He served as SSRL Director from 1998 to 2005, and SLAC National Accelerator Laboratory (SLAC) Deputy Director (2005-2007) and Associate Laboratory Director for Photon Science (2007-2011).
Today the Hodgson research group investigates how molecular structure at different organizational levels relates to biological and chemical function, using a variety of x-ray absorption, diffraction and scattering techniques. Typical of these molecular structural studies are investigations of metal ions as active sites of biomolecules. His research group develops and utilizes techniques such as x-ray absorption and emission spectroscopy (XAS and XES) to study the electronic and metrical details of a given metal ion in the biomolecule under a variety of natural conditions.
A major area of focus over many years, the active site of the enzyme nitrogenase is responsible for conversion of atmospheric di-nitrogen to ammonia. Using XAS studies at the S, Fe and Mo edge, the Hodgson group has worked to understand the electronic structure as a function of redox in this cluster. They have developed new methods to study long distances in the cluster within and outside the protein. Studies are ongoing to learn how this cluster functions during catalysis and interacts with substrates and inhibitors. Other components of the protein are also under active study.
Additional projects include the study of iron in dioxygen activation and oxidation within the binuclear iron-containing enzyme methane monooxygenase and in cytochrome oxidase. Lab members are also investigating the role of copper in electron transport and in dioxygen activation. Other studies include the electronic structure of iron-sulfur clusters in models and enzymes.
The research group is also focusing on using the next generation of x-ray light sources, the free electron laser. Such a light source, called the LCLS, is also located at SLAC. They are also developing new approaches using x-ray free electron laser radiation to image noncrystalline biomolecules and study chemical reactivity on ultrafast time scales. -
