Research interests

Role of polypeptide hormones and phosphodiesterase enzymes in muscle cachexia, inflammation and hyperlactacidemia in burn injury; Role of polypeptide hormones in obesity


Dr. Balasubramaniam joined UC as a postdoctoral fellow in 1981, and has risen through the ranks and now holds a Tenured Professor appointment in the Department of Surgery with joint appointments in Cincinnati VA Medical Center and Shriners Hospitals for Children. He studies Polypeptide Hormones in Health & Disease, currently focusing on their role in obesity, cachexia and critical illness. He has to his credit: 1) >160 peer reviewed papers which have been cited > 4,600 times, 28 book chapters and > 90 presentations/abstracts. 2) has been successful in obtaining extramural funding from NIH, VA, Shriners Hospital for Children or Industries; 3) has been awarded 10 patents and received upfront licensing fee for few of his patents; 4) honored several times as one of the University of Cincinnati Faculty Inventor; recognized with University of Cincinnati Faculty achievement award in1996; NATO Collaborative Research Award; The Wellcome Trust Travel Award; 5) served as a member of NIH study sections, Editorial Boards, Organizing Committees of Neuropeptide Y International Meetings (FL, Japan, Australia) and Chaired Sessions; Reviewed publications for several Journals; Edited Books; has served University of Cincinnati and VA Committees.
