Research Activities

I am mainly interested in large scale structure formation. My focus concerns implementation of perturbation theory to uncover the relativistic corrections to observables. These corrections appear as we observe on our past light cone. Theses corrections are small and are important only on large scales. Given the high precision that future surveys will provide, these corrections offer new ways to test general relativity and early universe.
