Research Summary (Please click on Group Site link below for more details)

Developing methods for describing the assembly, interactions and three-dimensional structures of membrane proteins using biophysical and computational techniques, including NMR spectroscopy. Of particular interest are membrane proteins associated with virally-induced cancers, which have demonstrated membrane protein-mediated mechanisms of cellular transformation.
