The research of de Alwis focusses on applying string theory to particle physics phenomenology and cosmology. The main focus in the last few years has been on supersymmetry, its breaking, and what string theory tells about the latter. Another goal of this research is to get a viable model of inflationary cosmology as a natural outcome of string theory.
