Raghu Mahajan
Senior Research Scientist
Current Research and Scholarly InterestsMy research interests are wide-ranging:
1) In the context of gravity, how does spacetime emerge from its dual quantum system? How does the dual quantum system encode the answers to questions that involve local physics in semi-classical gravity? How do you avoid the "firewall" paradox in the context of black-hole evaporation?
2) How do you calculate electrical and heat currents in strongly-coupled many-body systems? How do you explain the linear-in-temperature resistivity in high-temperature cuprates?
3) Use tensor network methods to study electrical and heat transport and also the real-time dynamics of systems out of thermal equilibrium. -

Associate Professor of Chemistry
Current Research and Scholarly InterestsOur research centers on problems at the interface of quantum and statistical mechanics. Particular themes that occur frequently in our research are hydrogen bonding, the interplay between structure and dynamics, systems with multiple time and length-scales and quantum mechanical effects. The applications of our methods are diverse, ranging from chemistry to biology to geology and materials science. Particular current interests include proton and electron transfer in fuel cells and enzymatic systems, atmospheric isotope separation and the control of catalytic chemical reactivity using electric fields.
Treatment of these problems requires a range of analytic techniques as well as molecular mechanics and ab initio simulations. We are particularly interested in developing and applying methods based on the path integral formulation of quantum mechanics to include quantum fluctuations such as zero-point energy and tunneling in the dynamics of liquids and glasses. This formalism, in which a quantum mechanical particle is mapped onto a classical "ring polymer," provides an accurate and physically insightful way to calculate reaction rates, diffusion coefficients and spectra in systems containing light atoms. Our work has already provided intriguing insights in systems ranging from diffusion controlled reactions in liquids to the quantum liquid-glass transition as well as introducing methods to perform path integral calculations at near classical computational cost, expanding our ability to treat large-scale condensed phase systems. -
Brendan Patrick Marsh
Ph.D. Student in Applied Physics, admitted Autumn 2018
BioBrendan Marsh is a Ph.D. candidate in Professor Benjamin Lev’s research group at Stanford University. He investigates light-matter interactions in many-body quantum systems and explores their use as a computational resource. His work more generally includes experimental quantum optics and theoretical methods to describe open quantum systems. He received a master’s degree in applied mathematics and theoretical physics from the University of Cambridge in 2018 and a B.S. in physics and mathematics from the University of Missouri in 2017.
Besides quantum optics and computation, Brendan has worked on problems in the philosophy of quantum theory (with Jeremy Butterfield at the University of Cambridge) and single molecule biophysics (with Gavin King at the University of Missouri). Along with Gavin King, he invented the Hessian blob algorithm, a general-purpose machine vision algorithm which is finding applications in fields ranging from scanning probe microscopy to medical imaging. -

Shaili Mathur
Ph.D. Student in Biology, admitted Autumn 2021
BioI'm a PhD student in the Eco/Evo track in the Biology department at Stanford. I was at UCLA as an undergraduate, where I majored in Computational and Systems Biology and minored in Mathematics, and also completed my MS in Bioinformatics with Prof. Van Savage through the Departmental Scholar Program. I am interested in using theory and experimental techniques to understand evolutionary dynamics, information processing in biological systems, and complexity in biological systems.

Susan K. McConnell
Susan B. Ford Professor, Emerita
Current Research and Scholarly InterestsSusan McConnell has studied the cellular and molecular mechanisms that underlie the development of the mammalian cerebral cortex. Her work focused on the earliest events that pattern the developing forebrain, enable neural progenitors to divide asymmetrically to generate young neurons, propel the migration of postmitotic neurons outward into their final positions, and sculpt the fates and phenotypes of the neurons as they differentiate.

Nathan McDonald
Basic Life Science Research Associate, Biology
Current Research and Scholarly InterestsI am interested in the fundamental cell biology of neurons. In particular, I study how neuronal synapses are formed and function. Synapses are specialized intercellular junctions that facilitate rapid communication between neurons, and thus form the basis of neural circuits and nervous system function.
Within a synapse, synaptic vesicles containing neurotransmitters are released at a specific region termed the active zone. The active zone is composed of a variety of molecules that coordinate the tethering and priming of synaptic vesicles, the recruitment of ion channels to respond to action potentials, and the stabilization of the synapse through transmembrane connections to a postsynaptic cell.
A wide range of transmembrane proteins are capable of initiating synapse formation during development and provide specificity for targeting the proper postsynaptic cell, including Neurexins/Neuroligins, LRRTMs, DIPs/DPRs, and many Ig domain proteins. However, in all synapses, these molecules must signal to build a common active zone core. I am studying how the conserved active zone core assembles downstream of this complexity, a fundamental unresolved question in developmental neurobiology.
To study this problem, I use the simple and stereotyped nervous system of the nematode Caenorhabditis elegans. I use fluorescent imaging of endogenous proteins at single neuron and single synapse resolution, as well as genetic and biochemical methods. -
