Research Interest

The research in our group focuses on the development of chemical protein labeling (A), chemical genetic and chemo-optogenetic approaches (B) to facilitate the study of frontier biological questions related to cytoskeleton function (C). We will be particularly interested in understanding the mechanisms underneath metaphase spindle assembly for error-free chromosome segregation during cell division. The study will further guide us to rationally design protein-based therapeutics to treat diseases that are related to genomic instability, e.g., cancer.


Open Positions:

We are seeking for 2 talented postdocs and 2-3 lab technicians. Candidates are expected to have one of the following research background: organic chemistry, protein bioconjugation chemistry, chemical biology, medicinal chemistry, biochemistry, molecular biology, immune cell therapy (e.g. CAR-T), phage display, directed evolution, gene editing, mice genetics, algorithm implementation (e.g. MATLAB, Python, etc.) or related fields, and should have a deep interest in conducting multi-disciplinary research crossing chemistry and life sciences. For application, please send a cover letter and a full CV to PI’s email address: chenxihit@hit.edu.cn. Candidates who passed the initial interview are expected to provide the contact information of two references and the two reference letters from them. This recruitment will continue until all positions are filled.
