Research Interests

Online Education. I am interested in developing (and assessing the efficacy) of new innovative learning tools in online education. 

Theoretical cosmology with particular emphasis on inflation, cosmic strings, dark matter and dark energy.

High energy physics: string theory, quantum gravity and physics beyond the standard model with particular interests in the subjects of de Sitter spacetime and time-dependent backgrounds.
