Research Interests: Mechanisms of cell death in development and disease. Developmental processes of Caenorhabditis elegans.
My lab is interested in mechanisms of cell death, particularly those associated with apoptosis. During development and on into life, apoptosis eliminates unnecessary or badly damaged cells before they can adversely affect the health of the organism. Because the mechanisms that eliminate the cell are triggered within the cell itself, apoptosis is often referred to as “cellular suicide”. When apoptosis is inappropriately regulated, i.e. too active or not active enough, disease often results, ranging from neurodegenerative disorders to cancer. We study apoptosis in the model organism Caenorhabditis elegans, a small, genetically well-defined roundworm well-suited for this research. Using genetic, molecular biological and biochemical techniques, we are learning how apoptosis is repressed in healthy cells, and how that repression is released in cells fated to die. Because the core mechanism of apoptosis is highly similar between C. elegans and humans, we’re interested in using the results of our research to better understand how apoptosis is controlled in humans, and how that control is lost during the development of disease.
