Richard Gunasekera, Ph.D., has enjoyed a 20-year career in higher education as professor and a scientist in the field of Biochemical Genetics and Nanomedicine. He earned his bachelor’s in biochemistry at Baylor University, where he researched and published in organic synthesis as an undergraduate. Gunasekera earned a master’s degree in bio-organic chemistry from the University of Houston-Clear Lake, a master’s in molecular genetics and a doctorate in Biomedical Sciences at the Baylor University Medical Center in Dallas. Before coming to Biola, Gunasekera founded the Department of Biological Sciences at the University of Houston-Victoria and acted as the Department Head and later as Director of Graduate Studies. He has held faculty and research positions at Texas A&M University Health Science Center, the University of Houston-Clear Lake, and Rice University in Houston. Gunasekera’s research now spans several interdisciplinary fields such as cancer biology, forensic DNA studies, nanomedicine and biochemical genetics. He has also received awards for excellence in teaching, research and as a distinguished faculty member from his previous institutions. 

Working with his students and colleagues in research Gunasekera stays committed to the student and the classroom. He believes that all teaching in the sciences is an extension of rigorous research and discovery, and that a science professor is best when he professes what he practices in the laboratory. Thus, he considers teaching both graduates and undergraduates in the classroom and laboratory in a Christ-centered environment as his first calling. He is committed to work as a team member to contribute toward building a world class institution and continue to make Biola a national leader in the sciences.
