Brief description of current research: 

I am interested in obesity surgery outcomes and it’s influence on body composition and the resolution of associated medical comorbidities.  The sleeve gastrectomy and roux-en-y gastric bypass are distinctly different operations which influence body composition, diabetes resolution and reflux disease differently.  Identifying patients who would benefit from these interventions and maximizing outcomes through pre-operative education, post-operative support and proper patient selection is important in treating this pervasive disease.  I am involved in research investigated the use of automated intelligence, machine learning and video based assessment to improve outcomes and the way that we teach and evaluate bariatric surgeons.   I am also interested in sarcopenia and the influence that this often underdiagnosed condition has on clinical outcomes in a diverse set of patients including the obese, those being treated for malignancies and the critically ill.
