Our People

Hyun Jin Kwun
Research Instructor
Jin is particularly interested in determinants of MCV viral replication and is investigating a new protein-mediated mechanism for MCV viral latency. She is also broadly interested in host-pathogen interactions particularly that of the MCV early viral proteins with the cellular E3 ligase network.
Tuna Toptan
Research Instructor
Tuna joined the lab in 2010 and works on both Merkel cell polyomavirus (MCV) and Kaposi’s sarcoma-associated herpesvirus (KSHV). Some of her current projects are: Development of search tools for new pathogen discovery, role of human polyomaviruses in disease and cancer, and application of mitotic p4E-BP1(S83) as a potential biomarker. Tuna discovered a new rat polyomavirus and is the go to person for everything.
