Ramin Shiekhattar, Ph.D., Academic Director

Ramin Shiekhattar, Ph.D., joined the Sylvester Comprehensive Cancer Center in 2014 as Chief of the Division of Cancer Genomics and Epigenetics and Director of the Cancer Epigenetics Research Program. Dr. Shiekhattar is the Academic Director of the OGSR and has overseen the expansion of OGSR services to meet the changing needs of investigators. Dr. Shiekhattar’s research group has made important contributions to the identification and characterization of key mediators of epigenetic regulation and non-coding RNA processing that contribute to cancer development. A major focus of his current research is in deciphering the function enhancer lncRNAs in the context of cancer, using state-of-the-art genomics and proteomics approaches.
