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.

Bio Professor Carolyn Bertozzi's research interests span the disciplines of chemistry and biology with an emphasis on studies of cell surface sugars important to human health and disease. Her research group profiles changes in cell surface glycosylation associated with cancer, inflammation and bacterial infection, and uses this information to develop new diagnostic and therapeutic approaches, most recently in the area of immuno-oncology.
Dr. Bertozzi completed her undergraduate degree in Chemistry at Harvard University and her Ph.D. at UC Berkeley, focusing on the chemical synthesis of oligosaccharide analogs. During postdoctoral work at UC San Francisco, she studied the activity of endothelial oligosaccharides in promoting cell adhesion at sites of inflammation. She joined the UC Berkeley faculty in 1996. A Howard Hughes Medical Institute Investigator since 2000, she came to Stanford University in June 2015, among the first faculty to join the interdisciplinary institute ChEM-H (Chemistry, Engineering & Medicine for Human Health). Named a MacArthur Fellow in 1999, Dr. Bertozzi has received many awards for her dedication to chemistry, and to training a new generation of scientists fluent in both chemistry and biology. She has been elected to the Institute of Medicine, National Academy of Sciences, and American Academy of Arts and Sciences; and received the Lemelson-MIT Prize, the Heinrich Wieland Prize, and the ACS Award in Pure Chemistry, among many others. Her efforts in undergraduate education have earned the UC Berkeley Distinguished Teaching Award and the Donald Sterling Noyce Prize for Excellence in Undergraduate Teaching.
Today, the Bertozzi Group at Stanford studies the glycobiology underlying diseases such as cancer, inflammatory disorders such as arthritis, and infectious diseases such as tuberculosis. The work has advanced understanding of cell surface oligosaccharides involved in cell recognition and inter-cellular communication.
Dr. Bertozzi's lab also develops new methods to perform controlled chemical reactions within living systems. The group has developed new tools for studying glycans in living systems, and more recently nanotechnologies for probing biological systems. Such "bioorthoganol" chemistries enable manipulation of biomolecules in their living environment.
Several of the technologies developed in the Bertozzi lab have been adapted for commercial use. Actively engaged with several biotechnology start-ups, Dr. Bertozzi founded Redwood Bioscience of Emeryville, California, and has served on the research advisory board of GlaxoSmithKline.

Current Research and Scholarly Interests Our lab uses chemical, biochemical, and cell biological methods to study protease function in human disease. Projects include:
1) Design and synthesis of novel chemical probes for serine and cysteine hydrolases.
2) Understanding the role of hydrolases in bacterial pathogenesis and the human parasites, Plasmodium falciparum and Toxoplasma gondii.
3) Defining the specific functional roles of proteases during the process of tumorogenesis.
4) In vivo imaging of protease activity

Current Research and Scholarly Interests Our laboratory combines synthetic chemistry and developmental biology to investigate the molecular events that regulate embryonic patterning, tissue regeneration, and tumorigenesis. We are currently using genetic and small-molecule approaches to study the molecular mechanisms of Hedgehog signaling, and we are developing chemical technologies to perturb and observe the genetic programs that underlie vertebrate development.

Current Research and Scholarly Interests Genomic instability contributes to many diseases, but it also underlies many natural processes. The Cimprich lab is focused on understanding how mammalian cells maintain genomic stability in the context of DNA replication stress and DNA damage. We are interested in the molecular mechanisms underlying the cellular response to replication stress and DNA damage as well as the links between DNA damage and replication stress to human disease.

Current Research and Scholarly Interests Our focus is on building computational models of complex biological processes, and using them to guide an experimental program. Such an approach leads to a relatively rapid identification and validation of previously unknown components and interactions. Biological systems of interest include metabolic, regulatory and signaling networks as well as cell-cell interactions. Current research involves the dynamic behavior of NF-kappaB, an important family of transcription factors.

Current Research and Scholarly Interests Developing new mass spectrometry-based experimental and computational tools that advance the field of proteomics, and applying them to a variety of important biomedical paradigms, including antigen presentation in cancer, and monitoring host responses to the gut microbiome.
Professor of Chemical and Systems Biology and of Biochemistry
Current Research and Scholarly Interests My lab has two main goals: to understand mitotic regulation 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 identifying the design principles of regulatory circuits.
