Research

Levon is on a sabbatical leave from SFU, visiting the Department of Applied Mathematics and Theoretical Physics Relativity and Gravitation research group and the Centre for Theoretcial Cosmology. His research interests include cosmic microwave background, large scale structrure, tests of dark energy and modified gravity, cosmological magnetic fields, non-Gaussianity, cosmic strings and other topolofical defects.
