Dr. Yu received his BS degree from Wuhan University, Hubei, China. He came to United States through the CUSBEA (China–United States Biochemistry Examination and Application) program. He pursued postdoctoral training at Massachusetts General Hospital, Harvard University and UT Southwestern Medical Center at Dallas before joining the faculty of the Schepens Eye Research Institute, Harvard Medical School in 1993. In 2001, he was recruited to the Medical College of Georgia where he was a tenured associated professor. In 2004, he came back to WSU as a full professor with tenure and Director of Research at the Kresge Eye Institute. Dr. Yu has served as a reviewer for numerous science journals. In addition, he has been a grant reviewer for the National Institute of Health (regular member, AED and DPVS), domestic private foundations, and several international governmental, notably National Science Foundation of China, and private funding agencies.

Areas of Research
Corneal wound healing; ocular inflammation and infection, corneal innate immunity, diabetic peripheral neuropathy, ocular toxicity test.
The Yu’s laboratory investigates the molecular mechanisms underlying corneal epithelial wound healing and diabetic neurotrophic keratopathy, using corneal organ culture and animal models. Specifically, the lab studies the interactions of sensory nerve, intraepithelial dendritic cells, and epithelial cells in the cornea during wound healing and their defects in diabetic corneas which lead to delayed epithelial wound closure and impaired sensory nerve regeneration (diabetic peripheral neuropathy). The second project of Dr. Yu’s lab is to study ocular innate immunity and protection against microbial infection. Dr. Yu and colleagues have shown that activation of Toll-like receptors, particularly TLR5 prior to infection resulted in profound mucosal protection against a broad spectrum of keratitis causing pathogens. The focus in Dr. Yu’s lab is to define the molecular mechanisms underlying these protective pathways.
Dr. Yu's research has been supported multiple R01 grants by the National Eye Institute.
