Chris Sander

Professor in Residence of Cell Biology

The overall goal of our work is to solve biological problems using quantitative methods from bioinformatics, statistical physics, data sciences, statistics, computer science, and mathematics. We apply these computational methods to build predictive network models of molecular and cell-cell interactions, to support cancer precision medicine, and to make discoveries in structural and evolutionary biology.

Malcolm Whitman
Professor of Developmental Biology (HSDM)
Affiliate member of Cell Biology

The Whitman lab is interested in how signals are transduced into highly specific biological responses during embryogenesis, during physiological responses of an organism to stress or damage,  and  during the development of various disease pathologies.

Pere Puigserver
Professor of Cancer Biology (DFCI)
Professor of Cell Biology

Our laboratory is interested in nutrient sensing in mammalian cells and how it connects to the transcriptional machinery to control gene metabolic regulatory networks.

Marcia Haigis

Associate Professor of Cell Biology

The Haigis laboratory focuses on the molecular regulation of mitochondrial functions during aging and age-related disease. Our goal is to investigate how pathways that control aging, such as sirtuins, impact mitochondrial fuel utilization, bioenergetics and signaling. To achieve these objectives, we take a multidisciplinary approach that employs biochemical, cellular, and mouse modeling experiments to systematically dissect the mitochondrial pathways of interest.

Our laboratory is investigating the cellular processes and pathways that are involved in normal morphogenesis of epithelial tissues as well as those involved in the initiation and progression of epithelial tumors.

Professor Emeritus of Cell Biology
Professeur au Collège de France

Using molecular and genetic approaches, we are examining how various signals are integrated in undifferentiated cells in order to dictate cell fates and ultimately influence morphogenesis. Our main experimental system is Drosophila, but we are interested in exploiting this system as a tool to explore human biology and understand the underlying mechanisms of pathologies such as cancer.
