Dr. Ray is working to understand the mechanisms of hepatitis C virus persistence and end stage liver disease progression in humans. Her research group made a significant contribution in understanding the cross-talk between HCV and host cell factors in disease progression. Recently, her laboratory initiated work on microRNAs regulation, and currently plans to understand the relationship between microRNAs and HCV mediated liver disease progression. She is interested in identifying non-invasive biomarkers for early detection of HCC from different racial/ethnic patients.

In addition, her laboratory is engaged in cancer biology work. She showed that natural product (bitter melon) has anticancer activity. Currently, she is investigating its role in tumor microenvironment including immune modulation using oral and breast cancer model systems.
