Ying-Ju Sung, PhD
Ying-Ju Sung, PhD, is professor of anatomy in the Department of Basic Sciences. She received her PhD from City University of New York. She completed her postdoctoral fellowship at Columbia University in New York, and received her bachelor’s degree from Taipei Medical University in Taipei, Taiwan. Dr. Sung joined Geisinger Commonwealth School of Medicine from Columbia University College of Physicians and Surgeons where she was assistant professor in the Department of Pathology and Cell Biology since 2006 and, prior to that, associate research scientist in the Department of Anatomy and Cell Biology since 2001. Dr. Sung was instrumental in identifying a molecular pathway that is activated in chronic pain states and recently headed a drug development program at Columbia University to synthesize analgesics by targeting one of the kinases in the pathway.
The goal of Dr. Sung’s current research is to advance our drug discovery program, which aims to alleviate chronic pain toward the IND and preclinical trial stage. Our efforts are based on the revelation that the activation of protein kinase G-1alpha (PKG-1_) is required to initiate and maintain several chronic pain syndromes of somatic and visceral origin. We use a combination of molecular biological, cellular and behavior approaches to this end.
