Professor of Medicine (Endocrinology, Gerontology and Metabolism)
On Leave from 10/01/2023 To 07/31/2024Current Research and Scholarly InterestsOur 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.
Karel H. and Avice N. Beekhuis Professor of Cancer Biology
Current Research and Scholarly InterestsDr. 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.

Professor of Medicine (Pulmonary, Allergy and Critical Care Medicine)
Current Research and Scholarly InterestsBasic and translational research in lung stem cell biology, cancer, pulmonary fibrosis, COPD, and acute lung injury/ARDS. Upper airway stem cell CRISPR gene correction followed by autologous stem cell transplantation to treat Cystic fibrosis. Using lung organoids and precision cut lung slice cultures of mouse and human lungs to study molecular regulation of lung stem cells. Using transgenic mice to visualize Wnt protein transmission from niche cell to stem cell in vivo.

James Ferrell
Professor of Chemical and Systems Biology and of Biochemistry
Current Research and Scholarly InterestsMy 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
Professor of Biology
Current Research and Scholarly InterestsWe 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. -
Judith Frydman
Donald Kennedy Chair in the School of Humanities and Sciences and Professor of Genetics
Current Research and Scholarly InterestsThe 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.

Xiaojing Gao
Assistant Professor of Chemical Engineering
Current Research and Scholarly InterestsHow do we design biological systems as “smart medicine” that sense patients’ states, process the information, and respond accordingly? To realize this vision, we will tackle fundamental challenges across different levels of complexity, such as (1) protein components that minimize their crosstalk with human cells and immunogenicity, (2) biomolecular circuits that function robustly in different cells and are easy to deliver, (3) multicellular consortia that communicate through scalable channels, and (4) therapeutic modules that interface with physiological inputs/outputs. Our engineering targets include biomolecules, molecular circuits, viruses, and cells, and our approach combines quantitative experimental analysis with computational simulation. The molecular tools we build will be applied to diverse fields such as neurobiology and cancer therapy.

Charles Gawad
Associate Professor of Pediatrics (Hematology/Oncology)
BioOur lab works at the interface of biotechnology, computational biology, cellular biology, and clinical medicine to develop and apply new tools for characterizing genetic variation across single cells within a tissue with unparalleled sensitivity and accuracy. We are focused on applying these technologies to study cancer clonal evolution while patients are undergoing treatment with the aim of identifying cancer clonotypes that are associated with resistance to specific drugs so as to better understand and predict treatment response. We are also applying these methods to understand how more virulent pathogens emerge from a population of bacteria or viruses with an emphasis on developing a deeper understanding of how antibiotic resistance develops.
