Aditya Tatu received his Phd from the Department of Computer Science, University of Copenhagen, Denmark in 2010, after which he joined DAIICT, Gandhinagar. He is an Associate Professor at DAIICT since January 2019.

His research interests lie in the areas of Image, Signal and Geometry Processing, often relying on Variational methods, Differential Geometry, Linear algebra and (convex) optimization.
