Current Research and Scholarly InterestsWe study Herpes simplex virus type 1 as a model eukaryotic chromosome for the analysis of eukaryotic DNA replication and recombination
Jerome and Daisy Low Gilbert Professor and Professor of Biochemistry
Current Research and Scholarly InterestsTelomeres 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.
Emma Pfeiffer Merner Professor in the Medical Sciences
Current Research and Scholarly InterestsThe goal of our research is to elucidate the molecular mechanisms by which proteins and cholesterol are transported between specific membrane compartments. We are trying to understand how phosphorylation of Rabs may trigger Parkinson's Disease. We also study how cells acquire cholesterol from the diet and from LDL; cholesterol export from lysosomes is critical for normal cell function.
Ronald W. Davis
Professor of Biochemistry and of Genetics
Current Research and Scholarly InterestsWe are using Saccharomyces cerevisiae and Human to conduct whole genome analysis projects. The yeast genome sequence has approximately 6,000 genes. We have made a set of haploid and diploid strains (21,000) containing a complete deletion of each gene. In order to facilitate whole genome analysis each deletion is molecularly tagged with a unique 20-mer DNA sequence. This sequence acts as a molecular bar code and makes it easy to identify the presence of each deletion.

Professor of Medicine (Oncology) and of Biochemistry
Current Research and Scholarly InterestsOur laboratory seeks to understand how cells repair DNA damage. We currently focus on how non-homologous end joining proteins assemble on DNA ends to juxtapose them for repair of DNA double-strand breaks.
We are collaborating in the development of a point-of-care device to measure ammonia from a drop of blood. The device will facilitate diagnosis and management of urea cycle defects, liver disease, and chemobrain due to elevated ammonia.
Professor of Biochemistry and, by courtesy, of Chemical Engineering and of Chemistry
Current Research and Scholarly InterestsOur research is aimed at understanding the chemical and physical behavior underlying biological macromolecules and systems, as these behaviors define the capabilities and limitations of biology. Toward this end we study folding and catalysis by RNA, as well as catalysis by protein enzymes.
Patrick O. Brown
Professor of Biochemistry, Emeritus
Current Research and Scholarly InterestsDr. Brown's research group uses diverse experimental and computational methods to investigate the logic and mechanisms that control a genome's expression program. The Brown laboratory is systematically characterizing the genetic scripts that control the expression of our genes, in normal development and physiology and in diseases like cancer, with a particular focus on post-transcriptional regulation. The Brown lab also develops strategies and assays for early detection and diagnosis of cancer.
Professor of Biochemistry and of Microbiology and Immunology
Current Research and Scholarly InterestsWe study the interactions between infectious bacteria and the human host cell actin cytoskeleton. Listeria monocytogenes and Shigella flexneri are unrelated food-borne bacterial pathogens that share a common mechanism of invasion and actin-dependent intercellular spread in epithelial cells. Our studies fall into three broad areas: the biochemical basis of actin-based motility by these bacteria, the biophysical mechanism of force generation, and the evolutionary origin of pathogenesis.
Associate Professor of Biochemistry
Current Research and Scholarly InterestsScientific breakthroughs often come on the heels of technological advances; advances that expose hidden truths of nature, and provide tools for engineering the world around us. Examples include the telescope (heliocentrism), the Michelson interferometer (relativity) and recombinant DNA (molecular evolution). Our lab explores innovative experimental approaches to problems in molecular biochemistry, focusing on technologies with the potential for broad impact.
