Research Interests

Research focuses on lipid synthesis, analysis and therapeutic application of novel bioactive molecules targeting sphingolipid metabolism. Current research interest relates to organelle-targeting sphingolipids and organelle-targeting inhibitors of sphingolipid metabolizing enzymes concentrating on mitochondria and lysosomes. Lipidomics Shared Resource at MUSC, directed by me, provides conceptual and practical training in various aspects of lipidology, qualitative and quantitative analysis of lipid components from different biological materials, synthetic molecular tools to study lipid metabolism and assists investigators in experimental design, selection of lipid of interest and interpretation of the analytical results. Analytical approach is based on High Performance Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS) technology.
