Professor Cesarman’s laboratory at Weill Cornell Medical College is involved in studying the process of viral oncogenesis in human cancer. She is co-PI on a five-year, $4.2 million grant by the National Cancer Institute, part of the National Institutes of Health, to investigate the molecular mechanisms by which immune cells called B cells interact with Epstein-Barr virus (EBV) to cause lymphoma, particularly in people living with HIV.
