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 each of the primary protease families.
2) Understanding the role of proteolysis in the life cycle of 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 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.

Current Research and Scholarly Interests My laboratory studies conformational switches in evolution, disease, and development. We focus on how molecular chaperones, proteins that help other biomolecules to fold, affect the phenotypic output of genetic variation. To do so we combine classical biochemistry and genetics with systems-level approaches. Ultimately we seek to understand how homeostatic mechanisms influence the acquisition of biological novelty and identify means of manipulating them for therapeutic and biosynthetic benefit.

Current Research and Scholarly Interests Our lab applies biochemical and engineering principles to the development of protein-based tools for molecular imaging and gene therapy. Topics of investigation include fluorescent proteins structure and biophysics, fluorescent protein-based biosensors, spatiotemporal analysis of protein translation pathways, chemical control of protein translation, and light-responsive proteins.

Current Research and Scholarly Interests CELLULAR INFORMATION PROCESSING The main problem in signal transduction is to understand how different receptor-stimuli specifically control diverse cell functions. We are using automated microscopy, live-cell fluorescent biosensors and perturbations of predicted signaling proteins to systematically dissect signaling networks. This allows us to identify signaling modules and to elucidate and ultimately model the flow of cellular information.
Beverly S. Mitchell, M.D.
George E. Becker Professor in Medicine and Professor, by courtesy, of Chemical and Systems Biology
Current Research and Scholarly Interests Beverly Mitchell's research relates to the development of new therapies for hematologic malignancies, including leukemias and myelodsyplastic syndromes. She is interested in preclinical proof of principle studies on mechanisms inducing cell death and on metabolic targets involving nucleic acid biosynthesis in malignant cells. She is also interested in the translation of these studies into clinical trials.
