Current Research and Scholarly InterestsFunction 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.

BioProfessor 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). She is now the Baker Family Director of Stanford ChEM-H.
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, the ACS Award in Pure Chemistry, and the Chemistry of the Future Solvay Prize, among others.
The Bertozzi Group develops chemical tools to study the glycobiology underlying diseases such as cancer, inflammation, tuberculosis and most recently COVID-19. She is the inventor of "bioorthogonal chemistry", a class of chemical reactions compatible with living systems that enable molecular imaging and drug targeting. Her group also developed new therapeutic modalities for targeted degradation of extracellular biomolecules, such as antibody-enzyme conjugates and Lysosome Targeting Chimeras (LYTACs). As well, her group studies NGly1 deficiency, a rare genetic disease characterized by loss of the human N-glycanase.
Several of the technologies developed in the Bertozzi lab have been adapted for commercial use. Actively engaged with several biotechnology start-ups, Dr. Bertozzi cofounded Redwood Bioscience, Enable Biosciences, Palleon Pharmaceuticals, InterVenn Bio, OliLux Bio, Grace Science LLC and Lycia Therapeutics. She is also a member of the Board of Directors of Lilly.

Current Research and Scholarly InterestsOur 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 InterestsOur laboratory combines 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 InterestsResearch in my laboratory is aimed at understanding how eukaryotes replicate their DNA despite numerous challenges (collectively known as replication stress), and more generally – how eukaryotic cells safeguard genome integrity. Specifically, we are investigating: (i) mechanisms that regulate the activity of the replicative helicase during replication stress, (ii) mechanisms that control the inheritance of epigenetic information during replication, and (iii) mechanisms of ubiquitin-mediated regulation of genome maintenance. We utilize single-molecule microscopy to directly image fluorescently-labeled replication factors and track them in real time in Xenopus egg extracts. I developed this system as a postdoctoral fellow, and used it to monitor how the eukaryotic replicative helicase copes with DNA damage. We plan to further extend the capabilities of this platform to directly visualize other essential replication factors, nucleosomes, and regulatory post-translational modifications like ubiquitin chains. By elucidating molecular mechanisms responsible for maintaining genome stability, we aim to better understand the link between genome instability and cancer, and how these mechanisms can be harnessed to improve disease treatment.

Current Research and Scholarly InterestsOur research program integrates concepts of chemical biology, protein engineering and structure biology to design new therapeutic leads and generate probes to study biological processes. A key focus of our lab is insulin, an essential hormone in our body to reduce blood glucose levels. We generate synthetic libraries of insulin analogs to select for chemical probes, and investigate natural insulin molecules (e.g. from the venom of fish-hunting cone snails!) to develop novel therapeutic candidates. We are especially interested in using chemical and enzymatic synthesis to create novel chemical entities with enhanced properties, and leverage the strong expertise of our collaborators to apply our skill sets in the fields of cancer biology, immunology and pain research. Our ultimate goal is to translate our discovery into therapeutic interventions in human diseases.

Current Research and Scholarly InterestsGenomic 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 InterestsOur 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.
