About Me
I am a PhD student in the Department of Computer Science at the University of Warwick working under the supervision of Sayan Bhattacharya. My research is primarily in the area of dynamic algorithms. I am currently working as a student researcher in the Graph Mining Team at Google Research.
My research is being funded by the Engineering and Physical Sciences Research Council. I am also a member of the Theory and Foundations group and the Centre for Discrete Mathematics and its Applications (DIMAP).
Before starting my PhD, I received my Master of Engineering in Discrete Mathematics from the University of Warwick.
Research Interests
My research interests primarily lie within the field of algorithms, with a particular focus on dynamic algorithms, graph algorithms and clustering algorithms. Two problems that I am particularly interested in are k-clustering and edge coloring—and all of their static, dynamic, distributed and online variants.
