Postdoc Position – AI/ML, RNA Bioinformatics, Precision Medicine - Columbia University

Columbia University

United States New York New York


The Laboratory of Dr. Chaolin Zhang in Department of Systems Biology, Columbia University Irving Medical Center (CUIMC) has a postdoc position in the field of AI/ML, bioinformatics, computational genomics interested in RNA biology and RNA-based precision medicine.

Taking a multidisciplinary approach that tightly integrates biochemistry, molecular biology, genome engineering and high-throughput data analysis and integrative modeling, the Zhang Laboratory studies how RNA and proteins interact to form regulatory networks in the nervous system at the mechanistic and systems levels, how these networks contribute to intrinsic neuronal functional properties, and how such properties are implicated in health and disease. We are working to translate fundamental discoveries to RNA-based precision medicine for devastating disorders with unmet medical needs. The Zhang lab consists of a group of inspired and creative scientists from diverse background. Recent lab members have successfully transitioned into prominent academic and pharmaceutical industry positions. More information about the Zhang laboratory can be found at

The candidates will participate in and lead exciting projects that aim to understand fundamental mechanisms of RNA-protein interactions and alternative RNA splicing regulation in normal and disease contexts. Innovative computational and machine learning-based approaches will be used to develop predictive models for analysis of high-throughput genomic data, including large scale bulk/scRNA-seq and CLIP-seq in various cellular contexts, as well as other genomic and genetic variant datasets. The candidates will work in a dynamic environment and also work closely with experimental biologists. Strong mentorship will be provided to help them achieve their career goals.
