Academic Interests

Before joining the college, Dr. Roosan worked as a faculty at Keck Graduate Institute, School of Pharmacy and Health Sciences, Claremont Colleges. Prior to that, he was a faculty at Baylor College of Medicine and research scientist at the Houston VA Medical Center. Dr. Roosan currently teaches courses in core curricula related to Biostatistics, and Informatics. He has experience in teaching courses health data analytics, pharmacogenomics, population epidemiology and health informatics.

Research Interest

The goal of Dr. Roosan’s program of research is to promote health and reduce health disparities in chronic and under deserved population through the application of innovative informatics and data science methods. His passion in research revolves around applying informatics, data analytics and health information technology to leverage Big Data in health care to improve safety, quality and reduce costs. Dr. Roosan is currently working with projects on augmented reality, improving medication adherence, utilizing omics data, using artificial intelligence to predict adverse events and designing clinical decisions support systems.
