  • David Rehkopf

    David Rehkopf

    Associate Professor of Epidemiology and Population Health, of Medicine (Primary Care and Population Health) and, by courtesy, of Sociology, of Pediatrics and of Health Policy

    BioI am a social epidemiologist and serve as an Associate Professor in the Department of Epidemiology and Population Health and in the Department of Medicine in the Division of Primary Care and Population Health. I joined the faculty at Stanford School of Medicine in 2011.

    I am Director of the Stanford Center for Population Health Sciences. In this position, I am committed to making high-value data resources available to researchers across disciplines in order to better enable them to answer their most pressing clinical and population health questions.

    My own research is focused on understanding the health implications of the myriad decisions that are made by corporations and governments every day - decisions that profoundly shape the social and economic worlds in which we live and work. While these changes are often invisible to us on a daily basis, these seemingly minor actions and decisions form structural nudges that can create better or worse health at a population level. My work demonstrates the health implications of corporate and governmental decisions that can give the public and policy makers evidence to support new strategies for promoting health and well-being. In all of his work, I have a focus on the implications of these exposures for health inequalities.

    Since often policy and programmatic changes can take decades to influence health, my work also includes more basic research in understanding biological signals that may act as early warning signs of systemic disease, in particular accelerated aging. I examine how social and economic policy changes influence a range of early markers of disease and aging, with a particular recent focus on DNA methylation. I am supported by several grants from the National Institute on Aging and the National Institute on Minority Health and Health Disparities to develop new more sensitive ways to understand the health implications of social and economic policy changes.

  • Richard J. Reimer, MD

    Richard J. Reimer, MD

    Associate Professor of Neurology (Adult Neurology) and, by courtesy, of Molecular and Cellular Physiology

    Current Research and Scholarly InterestsReimer Lab interests

    A primary interest of our lab is to understand how nerve cells make and recycle neurotransmitters, the small molecules that they use to communicate with each other. In better defining these processes we hope to achieve our long-term goal of identifying novel sites for treatment of diseases such as epilepsy and Parkinson Disease. In our studies on neurotransmitter metabolism we have focused our efforts on transporters, a functional class of proteins that move neurotransmitters and other small molecules across membranes in cells. Transporters have many characteristics that make them excellent pharmacological targets, and not surprisingly some of the most effective treatments for neuropsychiatric disorders are directed at transporters. We are specifically focusing on two groups of transporters – vesicular neurotransmitter transporters that package neurotransmitters into vesicles for release, and glutamine transporters that shuttle glutamine, a precursor for two major neurotransmitters glutamate and GABA, to neurons from glia, the supporting cells that surround them. We are pursuing these goals through molecular and biochemical studies, and, in collaboration with the Huguenard and Prince labs, through physiological and biosensor based imaging studies to better understand how pharmacological targeting of these molecules will influence neurological disorders.

    A second interest of our lab is to define mechanism underlying the pathology of lysosomal storage disorders. Lysosomes are membrane bound acidic intracellular organelles filled with hydrolytic enzymes that normally function as recycling centers within cells by breaking down damaged cellular macromolecules. Several degenerative diseases designated as lysosomal storage disorders (LSDs) are associated with the accumulation of material within lysosomes. Tay-Sachs disease, Neimann-Pick disease and Gaucher disease are some of the more common LSDs. For reasons that remain incompletely understood, these diseases often affect the nervous system out of proportion to other organs. As a model for LSDs we are studying the lysosomal free sialic acid storage disorders. These diseases are the result of a defect in transport of sialic acid across lysosomal membranes and are associated with mutations in the gene encoding the sialic acid transporter sialin. We are using molecular, genetic and biochemical approaches to better define the normal function of sialin and to determine how loss of sialin function leads to neurodevelopmental defects and neurodegeneration associated with the lysosomal free sialic acid storage disorders.

  • Michael J Rosen, MD, MSCI

    Michael J Rosen, MD, MSCI

    Stanford University Endowed Professor for Pediatric IBD and Celiac Disease

    BioI am a pediatric gastroenterologist and physician scientist, who has been devoted to inflammatory bowel disease (IBD) research since beginning medical training over 20 years ago. I am also Director of the Stanford Center for Pediatric IBD and Celiac Disease. I have expertise crossing mucosal immunology and epithelial biology, formal training and experience in clinical and translational investigation with human biospecimens, and direct insight regarding the important clinical challenges caring for children with complicated IBD. My translational research program focuses on how the immune system regulates epithelial function in chronic intestinal inflammation as it relates to IBD. My clinical research program has focused on optimization of anti-TNF therapy in pediatric IBD, and in particular acute severe ulcerative colitis (ASUC). My laboratory has demonstrated a protective role for IL33, a cytokine that induces type 2 cytokines from T cells an innate lymphoid cells (ILCs), in acute oxazolone colitis through preservation of epithelial goblet cells and barrier function. In line with this finding, we have also shown in a large prospective patient cohort that mucosal expression of type 2 and type 17 immune response genes distinguishes ulcerative colitis (UC) from colon-only Crohn’s disease, and that type 2 gene expression is associated with superior clinical outcome in pediatric UC. We have now developed an organoid-immune cell in vitro culture system to demonstrate the ILC2-dependent mechanism through which IL33 induces goblet cell differentiation in the intestinal epithelium. I led the multicenter study Anti-TNF for Refractory Colitis in Hospitalized Children (ARCH) Study, which aims to establish determinants of anti-TNF response in pediatric ASUC and currently Co-Chair the Crohn's & Colitis Foundations Cohort for Pediatric Translational and Clinical Research in IBD (CAPTURE IBD) and PRO-KIIDS Pediatric IBD clinical research network.

  • Grant M. Rotskoff

    Grant M. Rotskoff

    Assistant Professor of Chemistry

    BioGrant Rotskoff studies the nonequilibrium dynamics of living matter with a particular focus on self-organization from the molecular to the cellular scale. His work involves developing theoretical and computational tools that can probe and predict the properties of physical systems driven away from equilibrium. Recently, he has focused on characterizing and designing physically accurate machine learning techniques for biophysical modeling. Prior to his current position, Grant was a James S. McDonnell Fellow working at the Courant Institute of Mathematical Sciences at New York University. He completed his Ph.D. at the University of California, Berkeley in the Biophysics graduate group supported by an NSF Graduate Research Fellowship. His thesis, which was advised by Phillip Geissler and Gavin Crooks, developed theoretical tools for understanding nonequilibrium control of the small, fluctuating systems, such as those encountered in molecular biophysics. He also worked on coarsegrained models of the hydrophobic effect and self-assembly. Grant received an S.B. in Mathematics from the University of Chicago, where he became interested in biophysics as an undergraduate while working on free energy methods for large-scale molecular dynamics simulations.

    Research Summary

    My research focuses on theoretical and computational approaches to "mesoscale" biophysics. Many of the cellular phenomena that we consider the hallmarks of living systems occur at the scale of hundreds or thousands of proteins. Processes like the self-assembly of organelle-sized structures, the dynamics of cell division, and the transduction of signals from the environment to the machinery of the cell are not macroscopic phenomena—they are the result of a fluctuating, nonequilibrium dynamics. Experimentally probing mesoscale systems remains extremely difficult, though it is continuing to benefit from advances in cryo-electron microscopy and super-resolution imaging, among many other techniques. Predictive and explanatory models that resolve the essential physics at these intermediate scales have the power to both aid and enrich the understanding we are presently deriving from these experimental developments.

    Major parts of my research include:

    1. Dynamics of mesoscale biophysical assembly and response.— Biophysical processes involve chemical gradients and time-dependent external signals. These inherently nonequilibrium stimuli drive supermolecular organization within the cell. We develop models of active assembly processes and protein-membrane interactions as a foundation for the broad goal of characterizing the properties of nonequilibrium biomaterials.

    2. Machine learning and dimensionality reduction for physical models.— Machine learning techniques are rapidly becoming a central statistical tool in all domains of scientific research. We apply machine learning techniques to sampling problems that arise in computational chemistry and develop approaches for systematically coarse-graining physical models. Recently, we have also been exploring reinforcement learning in the context of nonequilibrium control problems.

    3. Methods for nonequilibrium simulation, optimization, and control.— We lack well-established theoretical frameworks for describing nonequilibrium states, even seemingly simple situations in which there are chemical or thermal gradients. Additionally, there are limited tools for predicting the response of nonequilibrium systems to external perturbations, even when the perturbations are small. Both of these problems pose key technical challenges for a theory of active biomaterials. We work on optimal control, nonequilibrium statistical mechanics, and simulation methodology, with a particular interest in developing techniques for importance sampling configurations from nonequilibrium ensembles.
