Select from the following:
Dr. Polyak research focuses on the interactions between cells and viruses, including flaviviruses (hepatitis C (HCV), Zika (ZIKV)), filoviruses (Ebola (EBOV), Marburg (MARV)), arenaviruses (Lassa (LASV), Junin (JUNV)), and more recently, coronaviruses (SARS-CoV-2). One area of study is the cellular innate antiviral and inflammatory responses to virus infection. He also studies how natural products engage human cells to protect them from damage by virus infection and chronic inflammation, and have a current project focused on botanicals that suppress SARS-CoV-2 infection and inflammation. Dr. Polyak is also actively engaged on repurposing approved drug combinations that synergistically suppress globally threatening viruses including filoviruses, arenaviruses, and coronaviruses. Repurposing of approved drugs provides cost-effective antiviral countermeasures that can be deployed during the critical period between virus identification and the development of new vaccines, virus-specific drugs, and therapeutic antibodies.
