D'souza's research and teaching revolve around urban governance,
planning, affordable housing, livelihoods and small-town urbanism.
In late February 2017, students at Trinity University in San Antonio, Texas,
stole more than 200 flyers advertising D'souza's planned appearance at the university the first week of March.
In an October 16, 2012 article in World Magazine,
author Warren Cole Smith reported on D'souza's activities after a September 28 talk that year in Spartanburg,
South Carolina.[94] Smith said that D'Souza, who was married at the time, checked into a hotel with another woman, and left with her the following day.
