Wenbin Zhu, M.D., M.S.; Senior Research Associate

Wenbin Zhu

Dr. Zhu joined APOM in 2012 as a post-doctor working for Dr. Alkayed and accepted the new appointment as Senior Research Associate in Dr. Alkayed’s lab in 2015.  He previously graduated from Hunan Medical University and worked as a neurological physician more than 10 years in China. Dr. Zhu’s research interests focus on the pathophysiological mechanism and the seeking of possible neuroprotective agents of ischemic stroke. Dr. Zhu is specialized in the animal surgeries of MCAO model, CA/CPR model and OMAG scanning technique as well as the post-processing of OMAG data. In his free time, Dr. Zhu enjoys reading, movie, skiing and of course, the quality time with his family.

Lijuan (Helen) Liu, D.V.M.; Research Associate

Helen Liu

Lijuan (Helen) Liu, D.V.M., is a research associate.  She joined APOM in January of 2013.  Dr. Liu received her DVM degree in China. Most recently, Dr. Liu worked in Dr. Donna Van Winkle’s lab, studying the mechanisms of cardioprotection induced by opioid peptides and

epoxyeicosatrienoic acids. Specifically, she used cardiomyocytes isolated from adult or neonatal mouse to study signal transduction (PI3K-AKT pathway) transactivated by G protein-coupled receptors (opioid receptors and EGFR receptors). In addition, she also

provided service for other laboratory personnel from OHSU in providing basic training for cardiomyocyte isolations and culture. Currently, she is working as the lead technician for the APOM Research Histology Core, providing technical expertise and support for a variety of research projects.  Outside of the lab, Helen enjoys dancing and taking care her parents at home.
