My research focuses on the dual fields of bone disease and obesity metabolism. Within the bone field, my ongoing research projects include (1) studying skeletal health after bariatric (weight loss) surgery in obese patients, (2) determining the physiologic mechanisms involved in bone loss after bariatric surgery, and (3) using these insights to guide management of bone health in bariatric surgery patients. I have also examined the skeletal impact of proton pump inhibitors, diabetes, and sex steroids, and explored physiologic effects of parathyroid hormone (PTH) in the treatment of osteoporosis.
Key bone techniques that I am utilizing include high-resolution peripheral quantitative computed tomography (HR-pQCT) for the in vivo assessment of bone microarchitecture, microindentation for the estimation of cortical bone material strength properties, and 1H-magnetic resonance spectroscopy for the measurement of marrow adiposity characteristics.
Within the obesity field, my research is focused on the impact of gut microbiota modulation on human metabolism. Gut microbiota have been recently identified to play an important role in many aspects of human physiology, including regulating obesity and metabolism. Studies suggest that fecal microbiota transfer (FMT) from lean donors may induce weight loss and improve insulin sensitivity in recipients. I am exploring the use oral capsulized FMT as a novel technique to durably alter the gut microbiome and investigate changes in metabolic endpoints including body weight and insulin sensitivity. The ultimate goal is to determine whether induction of sustainable changes in the gut microbiome can be developed into a therapeutic intervention for obesity and the metabolic syndrome.
