Research Summary

My research will focus on one or more of three areas: 1) examining the mechanisms and points of action of interferon-inducible antiviral effector proteins, 2) attachment and entry characteristics of the above viruses and mutants thereof and 3) cloning for construction of various viruses and vaccine vectors.  There will be work with cell lines engineered to overexpress proteins as well as primary cells harvested from animals and infection of mice.
