Dr. Tripathi has an abiding interest in the clinical applications of basic research. His current research is mainly focused on how tumor suppressor proteins, which are downregulated or inactivated in several cancer types by distinct mechanisms, can be stabilized and reactivated and exploited for cancer treatment. Specifically, Dr. Tripathi and colleagues are exploring functions of the tumor suppressor protein Deleted in Liver Cancer 1 (DLC1) and the kinases and methyltransferases that regulate its functions in normal physiology and in cancer.
