Professional Summary

Dr. Hong studied mathematical modeling of circadian rhythms as a graduate student, and learned how to apply genetic and molecular biological approaches to problems of cellular regulation, using Neurospora crassa, a tractable experimental system for circadian biology. As a young investigator who has crossed disciplines from mathematical biology to genetics and molecular biology, Dr. Hong believes that such interdisciplinary approaches will lead to the innovative therapies of the future. He joined the Department of Molecular & Cellular Physiology in April, 2010.
