Current Research and Scholarly Interests One of Axel Brunger's major goals is to decipher the molecular mechanisms of synaptic neurotransmitter release by conducting imaging and single-molecule/particle reconstitution experiments, combined with near-atomic resolution structural studies of the synaptic vesicle fusion machinery.

Bio Ron Dror is an Associate Professor of Computer Science and, by courtesy, Molecular and Cellular Physiology and Structural Biology at Stanford University, where he is also affiliated with the Institute for Computational and Mathematical Engineering, the Stanford Artificial Intelligence Lab, Bio-X, ChEM-H, and the Biophysics and Biomedical Informatics Programs. Dr. Dror's research at Stanford addresses a broad set of computational biology problems related to the spatial organization and dynamics of biomolecules and cells.
Before joining Stanford in March 2014, Dr. Dror served as second-in-command of D. E. Shaw Research, a hundred-person company, having joined in 2002 as its first hire. At DESRES, he focused on high-performance computing and biomolecular simulation?in particular, developing technology that accelerates molecular dynamics simulations by orders of magnitude, and applying these simulations to the study of protein function, protein folding, and protein-drug interactions (part of a project highlighted by Science as one of the top 10 scientific breakthroughs of 2010).
Dr. Dror earned a PhD in Electrical Engineering and Computer Science at MIT, an MPhil in Biological Sciences as a Churchill Scholar at the University of Cambridge, and both a BA in Mathematics and a BS in Electrical and Computer Engineering at Rice University, summa cum laude. As a student, he worked in genomics, vision, image analysis, and neuroscience. He has been awarded a Fulbright Scholarship and fellowships from the National Science Foundation, the Department of Defense, and the Whitaker Foundation, as well as a Gordon Bell Prize and several Best Paper awards.
Assistant Professor of Molecular and Cellular Physiology
Current Research and Scholarly Interests We are interested in the structure, dynamics and function of eukaryotic transport proteins mediating ions and major nutrients crossing the membrane, the kinetics and regulation of transport processes, the catalytic mechanism of membrane embedded enzymes and the development of small molecule modulators based on the structure and function of membrane proteins.
Younger Family Professor and Professor of Structural Biology
Current Research and Scholarly Interests 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.

Current Research and Scholarly Interests We study the molecular events that give rise to the sensation of touch and temperature in C. elegans. To do this, we use a combination of quantitative behavioral analysis, genetics, in vivo electrophysiology, and heterologous expression of ion channels. We also collaborate with Pruitt's group in Mechanical Engineering to develop and fabricate novel devices for the study of sensory transduction.

Current Research and Scholarly Interests We are interested in the neuronal mechanisms that underlie synchronous oscillatory activity in the thalamus, cortex and the massively interconnected thalamocortical system. Such oscillations are related to cognitive processes, normal sleep activities and certain forms of epilepsy. Our approach is an analysis of the discrete components (cells, synapses, microcircuits) that make up thalamic and cortical circuits, and reconstitution of components into in silico computational networks.

Current Research and Scholarly Interests My research is focusing on correlating physiological changes of brain micro-circuits with resulting anatomical changes. Currently I am studying how the induction of synaptic plasticity results in a change in the number of synapses made between a pair of neurons, and whether sub-synaptic receptor localization can account for the mechanisms of certain synaptic states. I am testing two competing hypotheses: whether 1) certain subtypes of glutamate receptors are sorted based on interactions with the unique amino acid sequence of each subunit's C-terminal tail (tail-sorting model); or 2) long term potentiation/ depression results from changes in postsynaptic density and/or the volume of the postsynaptic spine (indiscriminate model). Understanding these processes will help address a variety of issues in normal and pathological brain functions, including the basic molecular and cellular mechanisms of learning and memory formation.
In another ongoing project, I am characterizing the myelination of inhibitory neurons and explore its functional significance. Only some neuron types form myelinated axons, for example cortical pyramidal cells, cerebellar Purkinje cells, and parvalbumin-expressing subclass of basket interneurons. Surprisingly little is known about the structural and molecular organization of myelin on different neuron types. Our preliminary data reveal that there are significant differences between the myelin of inhibitory and excitatory axons in cortex. My future studies will further compare molecular and structural features of myelinated axons of PV basket cells and excitatory neurons in cortical gray matter, as well as their involvement in cortical plasticity and pathology (multiple sclerosis model).

Current Research and Scholarly Interests We study molecular mechanisms of calcium signaling with a focus on store-operated CRAC channels and their essential roles in T cell development and function. Currently we aim to define the molecular mechanism for CRAC channel activation and the means by which calcium signal dynamics mediate specific activation of transcription factors and T-cell genes during development.
