    Current Research and Scholarly Interests Telomeres are nucleoprotein complexes that protect chromosome ends and shorten with cell division and aging. We are interested in how telomere shortening influences cancer, stem cell function, aging and human disease. Telomerase is a reverse transcriptase that synthesizes telomere repeats and is expressed in stem cells and in cancer. We have found that telomerase also regulates stem cells and we are pursuing the function of telomerase through diverse genetic and biochemical approaches.

    Professor of Radiation Oncology (Radiation and Cancer Biology) and of Genetics

    Current Research and Scholarly Interests Our research is aimed at defining the pathways of p53-mediated apoptosis and tumor suppression, using a combination of biochemical, cell biological, and mouse genetic approaches. Our strategy is to start by generating hypotheses about p53 mechanisms of action using primary mouse embryo fibroblasts (MEFs), and then to test them using gene targeting technology in the mouse.

    Current Research and Scholarly Interests Function of Hedgehog proteins and other extracellular signals in morphogenesis (pattern formation), in injury repair and regeneration (pattern maintenance). We study how the distribution of such signals is regulated in tissues, how cells perceive and respond to distinct concentrations of signals, and how such signaling pathways arose in evolution. We also study the normal roles of such signals in stem-cell physiology and their abnormal roles in the formation and expansion of cancer stem cells.

  • Helen M. Blau

    Helen M. Blau

    Donald E. and Delia B. Baxter Foundation Professor, Director, Baxter Laboratory for Stem Cell Biology and Professor, by courtesy, of Psychiatry and Behavioral Sciences

    Current Research and Scholarly Interests Prof. Helen Blau's research area is regenerative medicine with a focus on stem cells. Her research on nuclear reprogramming and demonstrating the plasticity of cell fate using cell fusion is well known and her laboratory has also pioneered the design of biomaterials to mimic the in vivo microenvironment and direct stem cell fate. Current findings are leading to more efficient iPS generation, cell based therapies by dedifferentiation a la newts, and discovery of novel molecules and therapies.

    Michele and Timothy Barakett Endowed Professor

    Current Research and Scholarly Interests Our lab studies the molecular basis of longevity. We are interested in the mechanism of action of known longevity genes, including FOXO and SIRT, in the mammalian nervous system. We are particularly interested in the role of these longevity genes in neural stem cells. We are also discovering novel genes and processes involved in aging using two short-lived model systems, the invertebrate C. elegans and an extremely short-lived vertebrate, the African killifish N. furzeri.

  • Howard Y. Chang, MD, PhD

    Howard Y. Chang, MD, PhD

    Virginia and D. K. Ludwig Professor of Cancer Research and Professor of Genetics

    Current Research and Scholarly Interests Our research is focused on how the activities of hundreds or even thousands of genes (gene parties) are coordinated to achieve biological meaning. We have pioneered methods to predict, dissect, and control large-scale gene regulatory programs; these methods have provided insights into human development, cancer, and aging.

  • Katrin Chua

    Katrin Chua

    Associate Professor of Medicine (Endocrinology, Gerontology and Metabolism)

    Current Research and Scholarly Interests Our lab is interested in understanding molecular processes that underlie aging and age-associated pathologies in mammals. We focus on a family of genes, the SIRTs, which regulate stress resistance and lifespan in lower organisms such as yeast, worms, and flies. In mammals, we recently uncovered a number of ways in which SIRT factors may contribute to cellular and organismal aging by regulating resistance to various forms of stress. We have now begun to characterize the molecular mechanisms by which these SIRT factors function. In particular, we are interested in how SIRT factors regulate chromatin, the molecular structure in which the DNA of mammalian genomes is packaged, and how such functions may link genome maintenance to stress resistance and aging.

  • Michael F. Clarke, M.D.

    Michael F. Clarke, M.D.

    Karel H. and Avice N. Beekhuis Professor of Cancer Biology

    Current Research and Scholarly Interests Dr. Clarke maintains a laboratory focused on two areas of research: i) the control of self-renewal of normal stem cells and diseases such as cancer and hereditary diseases; and ii) the identification and characterization of cancer stem cells. His laboratory is investigating how perturbations of stem cell regulatory machinery contributes to human disease. In particular, the laboratory is investigating epigenetic regulators of self renewal, the process by which stem cells regenerate themselves.

  • Tushar Desai

    Tushar Desai

    Associate Professor of Medicine (Pulmonary and Critical Care)

    Current Research and Scholarly Interests We investigate the cellular and molecular events that regulate proper development of the lungs, including how the gas exchange region is maintained and renewed throughout life. We apply this knowledge to dissect how dysregulation of these normal processes can cause or contribute to specific lung diseases like pulmonary fibrosis, emphysema, and lung cancer, and we are interested in uncovering how lung stem cells are regulated in the hopes of harnessing them as a regenerative therapy for patients.

  • James Ferrell

    James Ferrell

    Professor of Chemical and Systems Biology and of Biochemistry

    Current Research and Scholarly Interests My lab has two main goals: to understand the regulation of mitosis and to understand the systems-level logic of simple signaling circuits. We often make use of Xenopus laevis oocytes, eggs, and cell-free extracts for both sorts of study. We also carry out single-cell fluorescence imaging studies on mammalian cell lines. Our experimental work is complemented by computational and theoretical studies aimed at understanding the design principles and recurring themes of regulatory circuits.

  • Hunter Fraser

    Hunter Fraser

    Associate Professor of Biology

    Current Research and Scholarly Interests We study the evolution of complex traits by developing new experimental and computational methods.

    Our work brings together quantitative genetics, genomics, epigenetics, and evolutionary biology to achieve a deeper understanding of how genetic variation shapes the phenotypic diversity of life. Our main focus is on the evolution of gene expression, which is the primary fuel for natural selection. Our long-term goal is to be able to introduce complex traits into new species via genome editing.

    Current Research and Scholarly Interests The long term goal of our research is to understand how proteins fold in living cells. My lab uses a multidisciplinary approach to address fundamental questions about molecular chaperones, protein folding and degradation. In addition to basic mechanistic principles, we aim to define how impairment of cellular folding and quality control are linked to disease, including cancer and neurodegenerative diseases and examine whether reengineering chaperone networks can provide therapeutic strategies.

  • Or Gozani

    Or Gozani

    Dr. Morris Herzstein Professor

    Current Research and Scholarly Interests We study the molecular mechanisms by which chromatin-signaling networks effect nuclear and epigenetic programs, and how dysregulation of these pathways leads to disease. Our work centers on the biology of lysine methylation, a principal chromatin-regulatory mechanism that directs epigenetic processes. We study how lysine methylation events are generated, sensed, and transduced, and how these chemical marks integrate with other nuclear signaling systems to govern diverse cellular functions.
