Jia-Ray Yu, Ph.D.
Principal Investigator
Jia-Ray received his PhD from a joint graduate program in Genetics at Stony Brook University and Cold Spring Harbor Laboratory in 2015. He conducted his thesis work on TGF-β and small GTPase signaling in lung cancer metastasis at CSHL under Dr. Linda Van Aelst. He then pursued his postdoctoral training in chromatin biology with Dr. Danny Reinberg at Howard Hughes Medical Institute (HHMI) and NYU Grossman School of Medicine. He started his independent research group in 2021 and his lab is interested in mechanisms-based inquiries in cancer and developmental epigenetics and leveraging basic science for translational applications.
Chih-Han Tu, Ph.D.
Postdoctoral Fellow
Chih-Han (Jeff) received his PhD in Biochemistry from the University of Oklahoma in 2025. His graduate work focused on functional analysis of bacterial toxins and anti-toxins. In Yu lab, Jeff is investigating structure-function regulations of mammalian histone methyltransferases and developing new pharmacological approaches to tackle these enzymes in human pathogentic conditions.
Jeff's publication from Yu Lab:
Tu et al, Epigenetics Reports (2026) (Invited review article)
