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.
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.
