My research interests are in string theory and related topics, with a focus on the interplay between string theory and quantum field theory. Currently my work is centered on aspects of the AdS/CFT correspondence in various dimensions. For instance, I have recently investigated higher spin gauge theories in AdS4 and their 3d CFT duals. Another research direction that I am pursuing is the calculation of quantum corrections in the AdS5 x S5 superstring sigma model, and comparison to the strong coupling expansion of certain observables in the 4d N=4 SYM theory. I am also interested in the dynamics of certain non-local operators in gauge theories, such as Wilson loops, and their dual string theory description.
