Josh (Hyo Sik) Jang, Ph.D.
Postdoctoral fellow, Peter Jones Laboratory and Dr. Stephen Baylin


Dr. Josh Jang has a Ph.D. in molecular genetics and genomics from Washington University in St. Louis and a B.S. in health promotion and disease prevention from University of Southern California. His graduate work focused on characterizing transposable elements’ contribution to oncogenic potential in cancer cell line models, as well as other projects that established and optimized targeted epigenetic technologies using CRISPR-Cas9 technology. In 2020, Dr. Jang joined Van Andel Institute as a VAI Fellow under Drs. Peter A. Jones and Stephen S. Baylin.

Current research focus

Combinations of epigenetic therapies and immunotherapies have shown synergistic promise in treating both solid and blood cancers with varying degree of clinical response. The molecular mechanisms and biology driving the discrepancy in response to therapy are under heavy scrutiny in hopes of improving treatment efficacy. As part of the Van Andel Institute—Stand Up To Cancer Epigenetics Dream Team, we will explore the dynamism of the immune landscape at tumor microenvironment and cell state resolution using single-cell technologies to elucidate how patients’ immune system responds to epigenetic therapy (DNMTi) and immunotherapy (checkpoint blockade).
