Biological Sciences/ Biology*

 

*EFFECTIVE January 1, 2008 the name of the department will change from Biological Sciences to Biology. Beginning with the entering class of 2008, the Department of Biology will award the following graduate degrees: Doctor of Philosophy in Biology and Master of Science in Biology.

Modern biological research demands an interdisciplinary approach to address the most important problems. The Department of Biological Sciences/Biology is dedicated to the study of biological questions at all levels. Current research in the department spans a broad spectrum and includes:

• Cell, Molecular, Developmental and Plant Biology: protein folding, single molecule biophysics, regulation of gene expression, cell migration, signaling, intracellular protein trafficking, cytoskeleton, cell cycle
• Integrative, Organismal and Marine Biology: thermoregulation, sensory transduction, development, behavior
• Ecology, Evolution and Population Biology: ecology biodiversity, adaptation, evolution, conservation biology

The diverse range of interests and expertise in the department creates a challenging intellectual environment that encourages students to take innovative approaches to the study of fundamental questions in biology. In addition, Ph.D. students in biological sciences have the opportunity to gain valuable experience teaching in lecture and laboratory courses.
       The Department of Biological Sciences/Biology is located geographically in the heart of the Stanford campus in close proximity to the departments of chemistry, physics, the School of Engineering, the School of Medicine, and the School of Earth Sciences. The department includes the Hopkins Marine Station, located on the Monterey peninsula, which is dedicated to the study of marine organisms, and the Jasper Ridge Biological Preserve, a natural preserve close to the Stanford campus. The department also has close ties with the Carnegie Institution’s Departments of Plant Biology and Global Ecology, a private research institution located on the Stanford campus.
       The mission of the Department of Biological Sciences/Biology is to mentor and educate biology students at the graduate, undergraduate, and post-doctoral level. Scientific interactions between research groups in the department are fostered through an annual departmental retreat, a weekly departmental seminar series, and weekly research presentations by graduate students and post-doctoral fellows in the department. To accommodate the broad range of interests, three distinct academic tracks are offered for graduate study:

I. CELL, MOLECULAR, DEVELOPMENTAL, AND PLANT BIOLOGY
Students in this area apply cutting-edge techniques in genetics, cell biology, biochemistry, biophysics, plant biology and neurobiology to the study of basic biological phenomena. Research of the faculty in this segment of the department covers a wide range of topics including: protein folding and turnover, nuclear transport, regulation of the cell cycle and cytoskeleton, intracellular signaling, development and function of the nervous system, plant-microbe interactions, and plant development. Graduate students spend their first year taking classes and carrying out research rotations in three different laboratories of their choosing.
       At the end of the first year, students choose a lab in which to carry out their doctoral research, and the rest of their time in the department is devoted primarily to designing and executing original research under the mentorship of their doctoral advisor and a thesis committee.

II. INTEGRATIVE, ORGANISMAL AND MARINE BIOLOGY
Graduate students in this area have the opportunity to study a range of topics in physiology, neurophysiology and marine biology. In their first year, students take classes and carry out research rotations before choosing a lab in which to carry out their thesis research. Students gain experience in undergraduate teaching, and focus intensively on original research conducted under the mentorship of their doctoral advisor and a thesis committee.
       Many of the faculties in this track are at the Hopkins Marine Station, a research facility located in Pacific Grove, about 90 miles south of the Stanford campus. Graduate students interested in working with a faculty member at the Marine Station spend part of their first year taking courses on the main Stanford campus. The Marine Station is an independent campus with fully equipped modern laboratories and an excellent library. Both field and laboratory studies at Hopkins emphasize the unique adaptations of marine animals and plants to the intertidal, subtidal, deep-sea and coastal environments. Other research efforts use marine organisms in basic molecular, cellular and physiological studies.

III. ECOLOGY, EVOLUTION, AND POPULATION BIOLOGY
Students in this area study a broad range of conceptual and empirical questions from ecology, evolutionary biology and evolutionary genetics. Research groups work with a diversity of organisms, including bacteria, plants, birds, insects, reptiles, and marine invertebrates. Approaches are varied, and include field studies, laboratory investigations, computer modeling and mathematical analyses. Research groups in this segment of the department benefit from access to the nearby Jasper Ridge Biological Preserve. Jasper Ridge is a remarkable 1,189 acre preserve of plants and animals native to California, and has been used for research for over a century. The graduate student training program is tailored individually to each student, and emphasizes the development of research, communication, and teaching skills.

http://www.stanford.edu/~mudgett/

W. James Nelson10. Our research objectives are to understand cellular mechanisms involved in development and maintenance of cell polarity. Recent studies indicate that development of epithelial cell polarity is a multistage process requiring instructive extracellular cues (eg. cell-cell and cell-substratum contact) and reorganization of proteins in the cytoplasm and on the plasma membrane. Once established, polarity is maintained by targeting and retention of proteins to functionally distinct apical and basal-lateral plasma membrane domains.

Carla J. Shatz11. The major goal of research in the Shatz Laboratory is to discover cellular and molecular mechanisms that transform early fetal and neonatal brain circuits into mature connections, and in particular to determine the extent to which neural function during critical periods of development is needed for these circuits to tune up into adult patterns of connectivity.
http://www.stanford.edu/group/shatzlab

Kang Shen. We are interested in understanding how synapses are formed, the final step in wiring a nervous system. In particular, the molecular mechanisms underlying synaptic specify: how neurons recognize each other and how they make decisions about forming synapses between contacting neurites during development. We use molecular, genetic and cell biological tools to study this question in the nematode, C. elegans, which has a very simple nervous system containing only 302 neurons and approximately 6000 synapses.

Michael A. Simon. We use genetic and biochemical approaches to study three areas of developmental biology; planar cell polarity (PCP) in epithelial cells, control of cell shape, motility and the actin cytoskeleton by Src family protein tyrosine kinases, and control of cell fate specification by receptor tyrosine kinases.

Shauna C. Somerville, by courtesy1. We use a variety of approaches to identify host components of disease resistance and of susceptibility in the interaction between the model plant Arabidopsis and Golovinomyces cichoracearum (powdery mildew). Since the powdery mildews grow only on living host tissue, they must strike a balance between growth and damage of their host. Thus, the powdery mildew diseases are particularly interesting diseases in which to study host-pathogen interactions.

Tim Stearns. The central question in our work is how cells accurately segregate their genome at each cell division. The work is focused on the centrosome, a unique organelle at the center of the cell that organizes the cytoskeleton and serves as a site for integration of cellular signals. We use the tools of cell biology, genetics, and biochemistry in systems ranging from yeast to human cells to understand how the centrosome duplicates once per cell cycle, and how centrosome defects are involved in the genome instability that is observed in many types of cancer.
http://www.stanford.edu/~stearns/

Virginia Walbot. Our laboratory studies the behavior of MuDR/Mu transposons of maize to answer fundamental questions about transposon regulation and plant development. Without a fixed body size, how do plant cells cease division and how are Mu element excisions restricted to the final cell divisions? Plants lack a germ line, but a few floral cells differentiate to undergo meiosis - why does Mu transposition outcome change in pre-meiotic cells?

George N. Somero2. We study how changes in protein sequence and gene expression enable organisms to succeed in diverse marine environments, including the Antarctic ocean and rocky intertidal habitats. By comparing homologous proteins from animals adapted to different temperatures, we have shown that only minor differences in habitat temperature are sufficient to favor evolutionary changes. Abilities to shift gene expression adaptively in response to environmental change vary among species and may be critical in setting tolerance limits.
