Molecular mechanisms of Parathyroid Hormone osteoanabolic effects;
Osteoanabolic drug development.
Metabolic bone diseases
My integrated research program is aimed at identifying, characterizing, and validating targets for pharmacological intervention and development of rational, effective novel therapeutics for bone regenerative medicine. We use an integrated approach with biochemistry, molecular / cell biology, mouse molecular genetics and preclinical science to cover the full bench-to-bedside spectrum: target identification and characterization, high-throughput screening of small molecules for drug development, and validation of lead compounds.
