Research

Lipids are a diverse group of metabolites that function as energy stores, components of membranes, and signaling molecules, and dysregulation of lipid metabolism occurs in many diseases. While lipids have been traditionally studied using in vitro or genetic techniques, chemical biology approaches can enable the rapid and precise interrogation of lipid biology within living systems. Research in my laboratory centers on the chemical biology and cell biology of lipids and biological membranes. Our work encompasses both methodology development and hypothesis-driven, mechanistic research aimed at shedding light on how lipid properties such as structure and subcellular location impact biological function. Using cross-disciplinary approaches, we are focused on elucidating signaling functions of lipid second messengers including phosphatidic acid and phosphoinositides. A vital part of my research program involves development of innovative chemical imaging tools to monitor these individual lipid species, notably a technique for imaging phosphatidic acid production by phospholipase D enzymes termed IMPACT. Separately, we are revealing new roles for phosphoinositides in the regulation of ubiquitination and Wnt signaling through our studies of a new family of lipid-binding proteins. Knowledge obtained from our foundational studies and initial applications of our tools has inspired novel directions of inquiry into fundamental biological mechanisms and those relevant to several human diseases, including multiple sclerosis and several cancers.
