Principal Investigator

Taeyoung Hwang, PhD is an Investigator at the Lieber Institute for Brain Development and an Assistant Professor in the Department of Neurology and the Solomon H. Snyder Department of Neuroscience at the Johns Hopkins University School of Medicine. Dr. Hwang received a bachelor’s degree in Electrical Engineering and a master’s degree in Bioinformatics at Seoul National University, Seoul, South Korea, and a Ph.D. in Biomedical Engineering at the Johns Hopkins University. After completing postdoctoral training at the University of Colorado, Boulder (advisor: John Rinn), Taeyoung started his independent research lab at the Lieber Institute for Brain Development in September 2021.

Current Members

Heejin Lee, PhD joined the lab in 2022 as a Staff Scientist. Dr. Lee is working to measure RNA–protein interactions in chromatin and establish the experimental pipeline to evaluate histone modifications in cell lines and stem cells. Hee Jin received her doctoral degree in medical sciences from the Catholic University of Korea, School of Medicine, major in pharmacology and biology. Her previous work included finding biomarkers of alcohol, nicotine, and drug addictions through genetic and protein expression analysis for identifying pathophysiological mechanisms to diagnose and treat patients. She had experience as a teaching assistant in biochemistry and molecular biology experiment at Yonsei University Medical School, South Korea.


Yu Hsuan Lee, MS is a Research Associate in Dr. Taeyoung Hwang’s lab. She joined the lab in 2021. She is working to develop high-throughput assays for RNA-protein interactions.


Arun Patil, PhD joined the lab in 2023 as a postdoctoral fellow. As a computational biologist (bioinformatics) his research involves data analysis from various omics platforms including next-generation sequencing-based small RNA sequencing, transcriptomics and single nuclei data analysis. His work extends to mass-spectrometry-based proteomics and integrating transcriptomics and proteomics to find novel translational events in several neurological disorders.
Prior to joining LIBD, he worked as a post-doctoral fellow in Dr. Marc Halushka’s lab, Department of Pathology, Division of Cardiovascular Pathology, the Johns Hopkins University, where he developed software tools to analyze microRNA sequences (miRge3.0) and carried out subsequent profiling of miRNAs using miRge3.0 in 196 primary cells from ~2000 samples.
