I was trained as a geneticist and have developed a research program that has applied genetic and biochemical approaches to understanding human lipid metabolism. Consequently, my colleagues and I have established a gene discovery strategy that has identified several novel pathways of eukaryotic lipid homeostasis. Particular success has been attained with regard to sterol and lipid transport and most recently the role of lipotoxicity in human diseases such as obesity, diabetes and neurodegeneration (mainly through our studies on Niemann Pick type C (NP-C) disease). My laboratory combines genetic, genomic, biochemical and metabolic approaches in model microorganisms ranging from yeast and marine algae, to murine and human models. Most recently, we have identified modifier pathways for autosomal recessive disorders such as Niemann Pick type C. This has led directly to a clinical trial for histone deacetylase (HDAC) inhibitors as well as the identification of phospholipid metabolic reactions as risk factors for NP-C disease. In all instances, our studies were initiated in microbial models, advanced to animal systems (mouse) and then extrapolated to human diseases.
