Clinical Informatics Research Division
Department of Epidemiology and Biostatistics
The University of Texas Health Science Center
San Antonio, TX, USA


After eighteen years of research in informatics methods and technical development of data-centric information systems-reaching from prevention to treatment and rehabilitation- he have a proven, documented track in research information systems strategy development and implementation, while leading research projects within the framework of multidisciplinary scientific collaborations in biomedicine.
As the Chief and Founder of the Clinical Informatics Research Division of University of Texas Health Science Center at San Antonio, He lead a full-spectrum biomedical informatics program and explore the intersection between informatics, translational science and clinically relevant data-centric problems including, but not limited to, computable phenotype-based research in health disparities, obesity, amyotrophic lateral sclerosis, ageing and cancer. Under the umbrella of successful PCORI awards, he created and maintain an information research system for interdisciplinary collaboration between pediatric endocrinologists, cancer researchers and neurologists, creating new institutional governance frameworks along the way with support from San Antonios CTSA hub, the institute for the integration of Medicine and Science.
Previous to arriving at the University of Texas, he served at Emory University School of Medicine as Associate Director for the Biomedical informatics Care at the Center for AIDS Research at the Rollons School of Public Health. He also served as Scientific Member of the Winship Cancer Institute Prevention ans Control Program and Senior Member of the Research Staff at the Center for Comprehensive informatics. His work at Emory University focused on informatics applied to clinically-relevant biomedical challenges including the correlations between infectious disease and cancer, as well as whole genome sequencing for vaccine development research, with support from the Atlanta Clinical and Translational Science Institute, Atlantas CTSA hub which includes the Georgia institute of Technology and Morehouse School of Medicine.
As a results-oriented biomedical technology leader, He have had the pleasure of developing many strong international relations at various academic institutions across the United States and Europe, as well as connections with regional academic networks (e.g. via the Patient Centered Outcomes Research Institute networks and the Clinical and Translational Science Award infrastructure).

Research Interest
