My research is primarily in operator algebras, specifically C*-algebras. Currently, my specialized interests are in structural properties and families of representations of C*-algebras,  as well as questions regarding lifting maps between C*-algebras. I am also particularly interested in universal C*-algebras and full C*-algebras associated to locally compact and discrete groups.
