The central theme of our research is to investigate the role of lipids in membrane-related transformations that take place during cellular processes that are important for human health and disease.
Our research program aims to functionally characterize the involvement of lipids in various decision-making processes of the cell, including cessation of cell division (replicative senescence) and death (i.e. apoptosis and necroptosis). At a fundamental level, our work investigates how subtle differences in chemical structure of lipids affect their biological function. Overall, our work aims to:
i) determine unknown functions of lipid in membrane-related phenotypes that accompany different cellular fates,
ii) identify biochemical mechanisms that results in their regulation cell fates, and
iii) targetable lipid biosynthesis-related enzyme to perturb these processes and membrane-related change that are associated with these processes.
We have a unique expertise at the interaction of bioanalytical chemistry and chemical biology. We leverage liquid chromatography-mass spectrometry-based lipidomics as a powerful discovery tool to obtain the chemical resolution we need while analyzing the changes in cellular lipidomes. We then use chemical biology and biochemistry to investigate the role of individual lipids that we prioritize based on the lipidomics.
