Research Interests

My main research interests have, over the years, focused on non-perturbative properties of field theories, the 1/N expansion, strings and superstrings. My recent work relates to the identification and possible gravitational descripiton of a closed radial sector of multi-matrix systems and a contructive approach to the O(N) Vector/Higher Spin Correspondence from collective fields.
