Han was born in 1986 in Changchun, Jilin, China. He obtained his undergraduate degree from the University of Science and Technology of China (USTC) where he graduated with a B.S. in chemistry and an honors degree in physical science. He conducted undergraduate research in Prof. Liu-Zhu Gong’s group, focusing on organic methodology and synthesis of natural products. After graduating from USTC in 2010, Han joined the Ph.D. program at the Scripps Research Institute (TSRI). His thesis work with Prof. Peter G. Schultz focused on expanding the technique of genetically incorporating unnatural amino acids in both prokaryotic and eukaryotic organisms and applying this technique for better cancer therapeutics. In 2015, Han joined the laboratory of Prof. Carolyn R. Bertozzi as a Good Ventures Postdoctoral Fellow of the Life Science Research Foundation at the Stanford University. In his postdoctoral work, he is engaged in the development of novel cancer immune therapy targeting the cell-surface glycans axis of immune modulation. Enzymatic precision glycocalyx editing is able to simultaneously stimulate immune-activating pathways and limit immune-inhibitory pathways within immune cells, thus leading to a promising avenue for cancer immune therapy. In July, Han started his independent research at Rice University. The focus of his research is the development of various chemical biological tools allowing us to understand complex biology system as well as develop novel therapeutic strategies. His research combines elements from multiple disciplines spanning synthetic chemistry, chemical biology, molecular biology, cancer biology and immunology.


Research Understanding complex biological systems and developing novel therapeutic approaches requires explorations at the interface of chemistry and biology. The focus of our research is the development of various chemical tools that allow us to precisely probe and manipulate biological systems. Our research combines elements from multiple disciplines spanning synthetic chemistry, chemical biology, molecular biology, cancer biology, and immunology. Precision modification of bio-molecules The ability to site-specifically introduce distinct chemical moieties (e.g. unnatural amino acid, unnatural saccharide derivatives) into biomolecules affords a powerful tool to investigate and manipulate biological systems. Here, we will expand the tool set for this purpose. We are interested in (1) adding new building blocks with novel chemical, biological, and physical properties in different biological systems; (2) enhancing the performance of chemical biological tools in various species; (3) using these tools to better understand and ultimately control various biological processes; and (4) exploring the therapeutic utilities of these tools in the context of cancer, autoimmune, and metabolic diseases. Next-generation antibody therapy Monoclonal antibodies have emerged as a successful treatment for various cancers since the 1980s. Beyond inducing tumor cell death by blocking survival pathways, their success relies substantially on their ability to coat tumor cells and promote immune cells activations against the tumor. We are actively pursuing the design and synthesis of novel antibody conjugates that enabling tumor-specific delivery of toxins as well as site-specific activation of the immune system. Advances in chemical biological tools will enable us to prepare antibody conjugates with novel scaffolds that can overcome the problems of current therapy as well as carry out novel actions. Engineering of immune cells Therapies that enhance the immune response to cancer are proving revolutionary in the fight against tumors. Chimeric antigen receptor (CAR)-engineered immune cell therapy that endows the patient’s immune cells with reactivity for tumor cell surface molecules, is emerging as an effective and innovative treatment for cancer. However, the future utility of this technology in clinical settings is greatly limited by long production times, high production costs, and complicated handling processes. We are using various chemical biological tools to engineer CAR-immune cells to overcome these limitations.
