## Hi! I'm Dipayan...

I am a doctoral fellow at the Department of Computer Science (LIMOS / ISIMA) at the Université Clermont Auvergne, France under the supervision of Annegret K. Wagler , Florent Foucaud and Michael Henning working on domination-based identification problems in graph theory. My other areas of research interests include graph colorings, graph homomorphisms and graph modification problems. Find me and my work by clicking on any of the following icons:
