I am Vice President of Scientific and Research Development and founder of the Texas Liver Institute. Prior to joining Texas Liver Institute, I spent 11 years at Brooke Army Medical Center in the Department of Gastroenterology and Hepatology, where I served in many teaching and academic positions.
Research Interests:
I have conducted extensive research in hepatology, authored over 300 publications and presented my work at both national and international medical meetings. I am internationally recognized for my work in liver disease research and teaching.
I also serve as a Clinical Professor of Medicine at UT Health San Antonio and attend outpatient clinics.
