Yun Qiu, PhD

• Ph.D., Rutgers University, 1995
• Postdoctoral Fellow, Case Western Reserve University School of Medicine, 1995-1997

My Ph.D training was done under supervision of Dr. Robert M. Krug at Rutgers University. I studied the functions of influenza virus NS1 protein as an RNA binding protein to regulate host mRNA  nuclear export and splicing. After completing Ph.D degree in 1995, I joined Dr. Hsing-Jien Kung's lab at Case Western Reserve Univrsity School of Medicine as a postdoc fellow, focusing on the mechanisms of signal transduction by protein kinases and how they diversify their signaling in cancer cells. In 1998, I joined University of Minnesota School of Medicine as a tenure track Assitant Professor in Deprtment of Lab Medicine & Pathology, where my lab continued to study the role of several tyrosine kinases in prostate cancer cells. In 2002, my lab moved to University of Maryland School and Medicine. The current research interests in my lab are focused on molecular mechnisms underlying therapeutic resistance in prostate cancer.
