Research Activities

My main field of research is on gravitational lensing from the experimental point of view. I dod three week observation at la silla observatory. I am also working on theoretical side of this field. The other subjects of my interests is inflationary Cosmology and recently I have started data analyzing of CMB, WMAP Data.
