Yoojung Han

Yoojung Han studied biochemistry, materials engineering, and molecular biology broadly during her B.S. at Seoul National University. Then she found her interest in computational biology and bioinformatics, and moved into the field in the summer of 2020 as a member of the Chang lab.

In the Chang lab, Yoojung has led research on nanopore-based repeat expansion profiling in neurological diseases and computational pipeline generation for mRNA vaccine design. She is continually expanding her skill set to encompass all aspects, from wet lab experiments in molecular biology to data analysis and software development. Currently, she is working on expanding nanopore signal processing algorithms for custom sequencing applications, while exploring design principles for next-generation mRNA therapeutics.
