Dr. Li is a Professor at the Department of Pharmaceutical Sciences, and Director of the Center for Pharmacogenetics at the University of Pittsburgh School of Pharmacy. He received his M.D. and Ph.D. from the Fourth Military Medical University, Xi’an, China, and pursued his postdoctoral training with Dr. Leaf Huang. He became a faculty at the University of Pittsburgh School of Pharmacy in 2000.
Dr. Li has broad knowledge in medicine, biology, immunology, and drug and gene delivery and is the author or co-author of over 175 peer-reviewed articles and 34 review articles or book chapters. Dr. Li serves on the editorial boards of several journals. He also frequently serves on the review panels of NIH, DOD, VA, and other funding agencies.
Research in Dr. Li’s lab has been continuously supported by grants from various funding agencies including NIH, DOD, and American Heart Association (AHA).
Dr. Li has established a strong research program centered at the interface of biology/immunology and biotechnology. His lab has developed several novel delivery systems that are aimed to solve major issues in his fields through improved understanding of the fundamental aspects of drug formulations and comprehensive structure-activity relationship (SAR) study. His group proposed the concept of “new amphiphilic surfactants with interfacial drug-interactive motif”, which has helped to solve the problem of formulating many “hard-to-formulate” drugs (Molecular Pharmaceutics, 2013; Biomaterials, 2015). Another breakthrough from Dr. Li’s group is the development of ultrasmall nanocarriers for improved cancer treatment (Theranostics, 2020; Biomaterials, 2021, Materials Today, 2023). Dr. Li’s group has discovered that covalent coupling of nucleosides-based drugs (such as gemcitabine, azacitidine, cytarabine, decitabine, and others) into an amphiphilic polymeric carrier led to a drastic reduction in sizes from ~150 to ~15 nm. This system is highly effective in codelivery of various front-line water-soluble and water-insoluble drugs. Due to its ultrasmall size, this technology holds promise in overcoming the challenge of ineffective tumor accumulation and penetration seen in cancer patients. More recently, his group has developed another new delivery system that is highly efficient in tumor accumulation through targeting CD44 on tumor endothelial cells (ECs) (Nature Nanotechnology, 2023). This system is suitable for delivery of small molecules or nucleic acids alone or codelivery of both types of therapeutics.
In addition to the development of improved delivery systems, Dr. Li’s group has sought to uncover new mechanisms involved in resistance to cancer chemotherapy and/or immunotherapy. His lab has recently identified glutamate metabotropic receptor 4 (GRM4) as a novel negative regulator in antitumor immunity in multiple tumor models (Science Advances, 2021). More recently, Dr. Li’s group has identified Xkr8 as a novel gene that is critically involved in chemotherapy-induced immune suppression and cancer relapse, suggesting a new combination therapy via targeting Xkr8 (Nature Nanotechnology, 2023). Dr. Li’s group is also interested in developing new therapies for noncancerous diseases including cardiovascular diseases and liver diseases through developing improved delivery systems and identification of new therapeutic targets.
