Osteoporosis, rheumatoid arthritis, and bone acquisition and development are the principle focus application areas for his research. As a Principal Investigator he has been awarded two R01s from NIH related to the standardization of HR-pQCT and the development of 3D statistical mapping techniques for population-based analyses of bone quality. He is a co-investigator on a number of significant NIH-funded multicenter skeletal health projects, including Osteoporotic Fractures in Men (MrOS), and the Epidemiology of Diabetes Interventions and Complications (EDIC). He was a member of the joint International Osteoporosis Foundation, ASBMR, and ECTS working group that produced guidelines for the use of HR-pQCT in skeletal health studies. Recently his research interests have expanded to include the development of standardized methods for using HR-pQCT in pediatric populations through collaborations with Stanford University. At UCSF he is developing a multidisciplinary program to study skeletal development in transgender youth. Finally, he is a founding member of the SPECTRA group (Study GrouP for XTrEme-CT in RA) that aims to develop standard methods to detect and quantify early signs of progression and treatment response in rheumatoid arthritis using HR-pQCT.
