Bio statement

Dr. Liu is a physician-scientist and Professor in the Department of Anesthesiology, Critical Care, and Neurology at Perelman School of Medicine. He is the current co-Chair of the World Stroke Organization Taskforce for Prehospital Care (WSOTPC). One of Dr Liu’s primary interests is to reduce prehospital delays for stroke victims world-wide by working with a global multi-disciplinary team. After successfully implementing his novel Stroke education strategy, Stroke 120 in China, in conjunction with Dr. Jing Zhao, a neurologist at Fudan University in Shanghai, Dr. Liu and his multi-disciplinary team also created Stroke 112 for other non-English speaking countries and regions. These educational strategies, based on the English program, FAST (Face, Arm, Speech, Time), for rapid stroke recognition and action, are currently being implemented in several countries or regions where English is not the primary language. Dr. Liu was appointed as Director of the Stroke 120 Special Task Force by the Chinese Stroke Association in 2017. Dr Liu is a current China Research Engagement Fund ($100K) recipient to promote and study Stroke 120 in China. If you are interested in joining his multi-disciplinary team in reducing pre-hospital delays for stroke victims worldwide, please email him at: 

Dr. Liu's Wake Up Stroke 120 won 2 awards at New York City International Film Festival, taking home Best Short Narrative Film and the Humanitarian Award. Wake Up Stroke 120 is a 10-minute educational movie that documents the tragic results of delayed medical attention for stroke. Dr. Renyu Liu was recently appointed as co-chair for the World Stroke Organization task force on Prehospital Care

Dr Liu has worked with Rosemary Polomano, PhD, RN, FAAN, and Joshua Atkins, MD, PhD, on a joint Penn Nursing and Medicine collaboration to improve post-surgical Pain management in China with funding support from the Penn Global. 

Dr. Liu also has an active basic research lab, funded by an NIH-R01, studying novel compound(s) as opioid receptor ligands for clinical usage through an understanding of the structural-functional relationships of opioid and opioid receptors.
