Biography

 Hijai Regina Shin completed her bachelor’s degree in Biology and her Ph.D in Molecular Biology in Seoul National University, South Korea. Her Ph.D. research focused on the epigenetic and transcriptional regulation of autophagy and lysosome functions.  Dr. Shin then joined the laboratory of Roberto Zoncu at the University of California Berkeley where she studied the mechanisms of nutrient sensing and cellular quality control, with emphasis on the signaling role of cholesterol and how it governs lysosome functions, cellular growth and metabolism. She gained expertise in techniques for the high-purity organelle immune-isolation and mass spectrometry-based analysis, along with an in-depth understanding of lipid metabolism. Moreover, in collaboration, she leveraged chemical biology approaches to develop new-generation inhibitors of the master growth regulator, mechanistic Target of Rapamycin Complex 1 (mTORC1) kinase, which may find application in disease settings driven by aberrant mTORC1 or dysregulated autophagy.

     In 2024, Dr. Shin joined the faculty of Children's Medical Center Research Institute at UT Southwestern as an Assistant Professor. The Shin lab combines unique expertise in cell biology, biochemistry, chemical biology and organelle physiology to uncover new connections between cholesterol sensing, impact on organelle functions and regulation of gene expression programs. The lab aims to undercover how inter-organelle communication dictates downstream metabolic response following environmental changes, and how breakdown of this communication leads to cancer aggressiveness and the development of other age-related diseases.
