Research and Clinical Interests

My research activities are aimed at understanding novel signaling pathways in preadipocytes and adipocytes using cell culture and mouse models. More specifically, we are interested in the roles of the FoxO family of forkhead transcription factors in lipid metabolism and how they impact on triacylglycerols accumulation. Other activities include the characterization of the mechanisms that allow transgenic mice overexpressing leptin to transition from a fatless to fat accumulating state as a result of aging or a high fat diet. Clinical research is aimed at the continuous development and implementation of novel molecular diagnostics assays and monitoring their impact on patient care and prognosis.
