In 2004, I joined this institution, then called The Scripps Research Institute (TSRI) Scripps Florida, as Professor. In 2007 I was named Professor and founding Chair of the Department of Molecular Therapeutics. Since then, I have become Scientific Director of what is now UF Scripps Biomedical Research. As PI, Co-PI, and co-investigator on several NIH-funded grants, my research continues to focus on protein structure and function, particularly on mutational- and ligand-mediated alterations in protein structural plasticity, as well as quantitative SAR to facilitate lead optimization of molecules targeting therapeutic proteins.

Using mutagenesis, HDX-MS, crystallography, proteomics and genomics my research is focused on structure-function of nuclear receptors, enzymes, and G protein coupled receptors (GPCRs). My research program has a major focus on understanding nuclear receptor (NR) signaling using structural, chemical and biological approaches. We have made significant contributions to understanding the mechanism of ligand activation of NRs such as PPARs, RORs, REV-ERBs, LRH1, VDR, ER, GR, and PR.
