Dr. Lian received his medical degree from Jilin University in China, and PhD degree in Neurosciences from Loyola University Chicago. He completed his residency training and research fellowships at the teaching hospitals of Harvard Medical School. Besides being an attending physician, providing patient care and teaching at the medical school, he is also an active investigator in medical research. Dr. Lian’s research interests focus on epigenetic regulation of gene expression by histone and DNA modification and its role in aging and related diseases. Using molecular biology techniques and transgenic animal models, his research shows that the newly discovered histone demethylase LSD1 plays an important role in energy metabolism, aging and the pathogenesis of aging related diseases, such as cardiovascular diseases.
