Current Research and Scholarly InterestsThe goal of our research is to advance experimental paradigms for understanding normal cognitive and disease processes at the level of neural circuits, with emphasis on learning and memory processes. To advance these paradigms, we invent optical brain imaging techniques, several of which have been widely adopted. Our neuroscience studies combine these imaging innovations with behavioral, electrophysiological, optogenetic and computational methods, enabling a holistic approach to brain science.
Assistant Professor of Biology
BioMolly Schumer is an Assistant Professor in Biology. She is interested in the genetic and evolutionary consequences of hybridization. After receiving her PhD at Princeton, she did her postdoctoral work at Columbia and was a Junior Fellow in the Harvard Society of Fellows and Hanna H. Gray Fellow at Harvard Medical School. Current research in the lab focuses on understanding genetic interactions that occur in hybrids and how these impact genome evolution.
Naima G. Sharaf
Assistant Professor of Biology and, by courtesy, of Structural Biology
BioNaima Sharaf got her undergraduate degree in Chemistry at the University of North Carolina-Chapel Hill. She carried out her Ph.D. studies at the University of Pittsburgh in the lab of Dr. Angela Gronenborn where she used fluorine solution NMR to understand inhibitor-induced conformational changes with HIV-1 reverse transcriptase. To expand her structural biology skill set, she undertook postdoctoral training at Caltech in the lab of Dr. Doug Rees where she characterized the structure and function of the Neisseria meningitides methionine ABC transport system using x-ray crystallography and single-particle cryo-EM. This research sparked Dr. Sharaf's current interest in lipoproteins, particularly their roles in bacterial physiology and potential in vaccine design. Research in the Sharaf Lab bridges biochemistry, biology, microbiology, and immunology to translate lipoprotein research into therapeutics.
Sapp Family Provostial Professor, The Catherine Holman Johnson Director of Stanford Bio-X and Professor of Biology and of Neurobiology
Current Research and Scholarly InterestsThe goal of research in the Shatz Laboratory is to discover how brain circuits are tuned up by experience during critical periods of development both before and after birth by elucidating cellular and molecular mechanisms that transform early fetal and neonatal brain circuits into mature connections. To discover mechanistic underpinnings of circuit tuning, the lab has conducted functional screens for genes regulated by neural activity and studied their function for vision, learning and memory.
Professor of Biology and of Pathology
Current Research and Scholarly InterestsThe connectivity of a neuron (its unique constellation of synaptic inputs and outputs) is essential for its function. Neuronal connections are made with exquisite accuracy between specific types of neurons. How each neuron finds its synaptic partners has been a central question in developmental neurobiology. We utilize the relatively simple nervous system of nematode C. elegans, to search for molecules that can specify synaptic connections and understand the molecular mechanisms of synaptic as

Professor of Biology and, by courtesy, of Chemical and Systems Biology
Current Research and Scholarly InterestsMy overarching goal is to understand how cell growth triggers cell division. Linking growth to division is important because it allows cells to maintain specific size range to best perform their physiological functions. For example, red blood cells must be small enough to flow through small capillaries, whereas macrophages must be large enough to engulf pathogens. In addition to being important for normal cell and tissue physiology, the link between growth and division is misregulated in cancer.
David and Lucile Packard Professor in Marine Science, Emeritus
Current Research and Scholarly InterestsWe examine two aspects of organism-environment interactions: How does stress from physical (e.g., temperature) and chemical (oxygen levels, pH) factors perturb organisms and how do organisms respond, adaptively, to cope with this stress? We examine evolutionary adaptation and phenotypic acclimatization using a wide variety of marine animals, including Antarctic fishes and invertebrates from intertidal habitats on the coastlines of temperate and tropical seas.
Assistant Professor of Geological Sciences and, by courtesy, of Biology and Center Fellow, by courtesy, at the Woods Institute for the Environment
Current Research and Scholarly InterestsThe research interests in the Sperling Lab are Earth history and the evolution of life, and the interactions between the biosphere and the geosphere. As such this research can generally be considered paleontology, insofar as paleontology encompasses all aspects of the history of life.
Consequently, we define our research agenda by the questions we are interested in, rather than the tools used. This research incorporates multiple lines of evidence, and multiple tools, to investigate questions in the history of life. These lines of evidence include fossil data, molecular phylogenetics, sedimentary geochemistry, and developmental and ecological data from modern organisms. Ultimately, the goal is to link environmental change with organismal and ecological response through the lens of physiology.
Our field research takes place all over the world--current areas include:
-NW Canada (Yukon and Northwest Territories): Research has been conducted on the early Neoproterozoic Fifteenmile Group, Cryogenian and Ediacaran Windermere Supergroup, and on the Ordovician-Devonian Road River Group in the southern Richardson Mountains
-Southern Canadian Cordillera: Work here has focused on the early Cambrian Mural Formation and its soft-bodied fauna.
-England and Wales: Cambrian-Silurian successions in the Welsh Basin
-Namibia: Ediacaran Nama Group
-Upwelling zones: We study the oxygen minimum zone offshore California as an analogue for ancient low-oxygen oceans.
Acting Dean of Research, Frank Lee and Carol Hall Professor, Senior Associate Vice Provost of Research and Professor of Genetics
Current Research and Scholarly InterestsWe use the tools of genetics, microscopy, and biochemistry to understand fundamental questions of cell biology: How are cells organized by the cytoskeleton? How do the centrosome and cilium control cell control cell signaling? How is cell division coordinated with duplication of the centrosome, and what goes wrong in cancer cells defective in this coordination?
