Current Research


NIDDK R01 DK073302, 2007-2012
Understanding How Patients Value Bariatric Surgery
This project uses a racially diverse cohort of 650 patients recruited from two bariatric centers and a cross-sectional sample of 600 primary care patients from the community. The goals of the project are to understand the value patients associate with weight loss and surgical outcomes and identify patients' perceptions of bariatric surgery and the factors they consider in deciding whether or not to undergo weight loss surgery. An important aim of the project will be to identify patients who derive greater value from surgery and potential factors and barriers that might explain current observed racial variation in the use of bariatric surgery.

Clinical and Autonomic Effects of Mind-Body Exercise in COPD
We propose a 3-arm randomized controlled trial to evaluate the effects of tai chi exercise versus seated mind-body breathing alone versus an education control on exercise capacity and quality of life in COPD patients.
