Brunger

Axel Brunger (Department Chair)  

Jointly appointed in Neurology & Neurological Sciences, Photon Science and, by courtesy, Structural Biology

We investigate the molecular mechanisms of synaptic neurotransmitter release by conducting single-molecule/particle reconstitution and imaging experiments, combined with high-resolution structural studies of the synaptic vesicle fusion machinery. Other interests include the development of approaches for biomolecular structure determination using advanced X-ray light sources, including X-ray free electron lasers.  More »

Chu

Steven Chu

Jointly appointed in Physics

From January 2009 until April, 2013, Dr. Chu served as the 12th U.S. Secretary of Energy during President Obama's administration. Prior to his Cabinet post, he was the Director of Lawrence Berkeley National Lab, Professor of Physics and Professor of Molecular and Cell Biology, University of California Berkeley and Professor of Physics and Applied Physics at Stanford University. Previous to those posts, he was with AT&T Bell Laboratories.  Dr. Chu is the co-recipient of the Nobel Prize for Physics (1997) for his contributions to the laser cooling and trapping of atoms. His other areas of research include tests of fundamental theories in physics, atom interferometry, study of polymers and biological systems at the single molecule level, and biomedical research. While at Stanford, he helped start Bio-X, a multi-disciplinary initiative that brings together the physical and biological sciences with engineering and medicine. More recently, he has focused on how to transition to a sustainable future.  More »

Chris GarciaChris Garcia

Jointly appointed in Structural Biology

Structural and functional studies of transmembrane receptor interactions with their ligands in systems relevant to human health and disease - primarily in immunity, infection, and neurobiology. We study these problems using protein engineering, structural, biochemical, and combinatorial biology approaches.  More »

GoodmanMiriam Goodman (Director of Training Programs)

We seek to deconstruct and understand how sensory neurons convert mechanical and thermal stimuli into neural signals perceived as touch, cold, heat, and pain.  We use in vivo electrophysiology, genetics, light and electron microscopy, and quantitative analysis of behavior to study this question in the nematode C. elegansMore »

Kobilka Brian Kobilka

Jointly appointed, by courtesy, in Chemical and Systems Biology

The Kobilka lab investigates the molecular mechanisms of G protein coupled receptor signaling.  G protein coupled receptors are responsible for the majority of cellular responses to hormones and neurotransmitters, as well as the senses of sight, olfaction and taste. We use a variety of biochemical and biophysical approaches to characterize the structure and dynamic properties of these receptors that are responsible for their versatile signaling behavior.  More »

NachuryMaxence Nachury (Director of Graduate Studies)

We study the primary cilium, a once-obscure cellular organelle recently "re-discovered" for its role in a number of signaling pathways. Defects in cilium biogenesis lead to a variety of hereditary disorders characterized by retinal degeneration, kidney cysts and obesity. Our goal is to characterize these disorders at the molecular and cellular levels to gain insight into the basic mechanisms of primary cilium biogenesis and to discover novel ciliary signaling pathways.  More »

SmithStephen Smith

Our laboratory explores the development, structure, function and disorders of the brain’s neural circuitry. The lab’s experimental approach has typically begun with the invention of a new optical imaging method followed by applications of that method to attack important but previously untractable experimental challenges.  Most recently, the lab invented a unique high-resolution proteomic imaging method called “array tomography”, and are now working to apply this novel method to explore the molecular architecture of cortical microcircuits in mouse and human. This work is currently focused on efforts to identify the circuit loci of the specific changes in synaptic connectivity associated with specific memory traces, i.e. the physical “engrams” of experience.  More »

Thomas C. Südhof Thomas C. Südhof

Jointly appointed, by courtesy, in Neurology & Neurological Sciences and Psychiatry & Behavioral Sciences

In brain, neurons primarily communicate with each other at synapses, which are highly plastic, and not only transfer, but also process and store information. My laboratory is interested in how synapses are formed, how synapses work at a molecular level and change during synaptic plasticity, and how synapses become dysfunctional in diseases such as autism and other neuropsychiatric disorders. To address these questions, my laboratory employs a variety of approaches ranging from biophysical and biochemical studies to electrophysiological and behavioral analyses of mutant mice. More »

Molecular interactions that underlie the establishment and maintenance of cell and tissue structure are studied with a variety of biochemical, structural, and biophysical methods. Specific areas of interest include cadherin-based adhesion and its interaction with the cytoskeleton, the relationship between cell-cell junction formation and generation of cell polarity, and the Wnt signaling pathway that controls cell fate determination.

ScherrerGregory Scherrer
Department of Anesthesia

Our laboratory investigates the cellular and molecular mechanisms of pain and its control by opioids. When chronic, pain is no longer an essential warning system critical to our survival, but a disease that severely affects the quality of life of many patients. We search to identity the neurons that participate in generating the sensation of pain and to uncover the molecular mechanisms that regulate neural activity in pain circuits. One of our goals is to elucidate the mechanisms by which opioids such as morphine generate analgesia and detrimental side effects, including addiction, to develop more efficient and safer analgesics. To this end we combine a variety of experimental approaches including molecular and cellular biology, neuroanatomy, electrophysiology, optogenetics and behavior.
