Research Experience

2016.7 - Current

Tenure Track Assistant Professor, Peking University, School of Pharmaceutical Sciences

Principal Investigator, State Key Laboratory of Natural and Biomimetic Drugs

 Development of novel biotherapeutics. We use a combination of molecular biology approaches, including genetic code expansion and molecular evolution (phage display, yeast display, library screening, etc.) to develop novel protein, antibody, and cell-based therapeutics.

Study the function of post-translational modification (PTM). We have a broad interest in the function and regulation of protein PTMs, such as phosphorylation, acetylation and ubiquitination. We are especially interested in protein tyrosine phosphorylation and how it involves in disease conditions.

2011.7 – 2016.3

Postdoctoral Research Associate, Department of Chemistry, the Scripps Research Institute. 

Advisor: Prof. Peter G. Schultz 

Scientist (part time), California Institute for Biomedical Research (Calibr)  

 Exploring expanded genetic codes in a variety of applications, including enhancing protein thermostabilities, probing protein post-translational modifications and modification of natural peptide products.

Development of antibody-CDR engineering strategies for generation of long acting therapeutic proteins and peptides in variety of disease models.

2005.7 – 2011.6

Graduate Research Associate, Department of Chemistry, The Ohio State University. 

Advisor: Prof. Dehua Pei

 Development of chemical methodologies for the combinatorial synthesis and screening of cyclic peptide libraries, and peptide engineering for enhanced binding affinity, solubility and cell permeability;

 Application of cyclic peptide libraries for the identification of inhibitors against protein receptors, protein domains and enzymes, as well as the hit optimization and biological evaluation.
