The aim of this work, in collaboration with Dr. Bjoern Peters, is to identify and characterize T cell epitopes from Mycobacterium tuberculosis in vaccination and active infection (NIH/NIAID, 75N93019C00067). We are also interested in defining human immune signatures of different stages of Mtb infection.

In collaboration with Dr. Tom Hawn at the University of Washington, we are characterizing immune responses against the non-tuberculous mycobacterium M. avium.
