Research Statement

For the first decade of its operation, my laboratory took a multi-pronged approach to identifying and characterizing novel genes involved in lipid and glucose metabolism. We now focus on the most promising leads from this search—fasting processes that contribute to the development of type 2 diabetes mellitus—in the hopes of developing better diagnostic and therapeutic modalities to treat this pandemic, multi-organ illness. The central area of study is how the transcriptional repressor FOXN3, whose gene locus is associated with fasting blood glucose in population genetic studies, acts to regulate metabolism. FOXN3 is silenced in a wide array of cancers via uniqee mechanisms (e.g., intron polyadenylation, targeted pre-mRNA decay), and I am establishing several mouse cancer models where FOXN3 is absent. A second major area is the study of the ketone body transporter SLC16A6, whose encoding gene is amplified in several cancers. This work spans human physiology, genetically engineered mice and zebrafish, and cell-based approaches. Other areas of interest over my career included intestinal lipid transport and development of novel insulins based on cone snail venom insulin. I am also interested in monogenetic diabetes and dyslipidemia syndromes, areas that interface directly with areas of interest in clinical effort.
