Dr. Campos' research interests are focused in the development of new minimally invasive (MIS) and endoscopic techniques for both foregut diseases and morbid obesity, and evaluation of the outcomes using established MIS and endoscopic treatments. In addition he is leading studies to determine detailed mechanisms by which bariatric surgery improves obesity associated diseases such as diabetes mellitus. He has published numerous peer-reviewed articles and written many chapters in books as well as presented his work at national and international meetings.
