Specific Clinical/Research Interests: Molecular determinants of virulence of emerging viruses, including Ebola virus and Marburg virus

Administrator: Christine Schwall

Current Students: PhD: Megan Edwards, Benjamin Yen

Postdoctoral Fellows: Alicia Feagins, Priya Luthra, Tshidi Tsibane, Heidi Karttunen, Toni Schwarz

Research Personnel: Matthew Kreitman

Summary of Research Studies:

The filoviruses, Ebola viruses and Marburg viruses, are emerging, zoonotic negative-strand RNA viruses. As the 2014 West Africa Ebola virus outbreak makes clear, the unique virulence and high transmissibility of these viruses makes them unique public health threats.  The Basler lab studies filovirus immune evasion and replication mechanisms with the goals of (1) developing therapeutics that target these mechanisms, (2) determining how these mechanisms contribute to viral pathogenesis and (3) understanding how these mechanisms function in different host species.

Industry Relationships

Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their relationships with such companies.

Dr. Basler did not report having any of the following types of financial relationships with industry during 2015 and/or 2016: consulting, scientific advisory board, industry-sponsored lectures, service on Board of Directors, participation on industry-sponsored committees, equity ownership valued at greater than 5% of a publicly traded company or any value in a privately held company. Please note that this information may differ from information posted on corporate sites due to timing or classification differences.

Mount Sinai's faculty policies relating to faculty collaboration with industry are posted on our website. Patients may wish to ask their physician about the activities they perform for companies.
