Siddharth Gupta (सिद्धार्थ गुप्ता)

Postdoctoral Researcher

I am currently a Postdoctoral Researcher at the Department of Computer Science at University of Warwick, UK advised by Professor Ramanujan Sridharan. Before that, I was a Zuckerman Postdoctoral Scholar at the Department of Computer Science at Ben-Gurion University, Israel advised by Professor Meirav Zehavi.

I received my PhD in Computer Science from University of California, Irvine in 2018, advised by Professor David Eppstein and Professor Michael T. Goodrich, and my Master in Mathematics and Bachelor in Computer Science from BITS-Pilani, Goa Campus in 2014, advised by Professor Ankit Agrawal and Professor Tarkeshwar Singh.

Research Interests

My research interests lie in Graph Algorithms and Computational Geometry, more specifically in Graph Drawing, Parameterized Complexity, Approximation Algorithms and, more recently, Fine-Grained Complexity and Combinatorial Reconfiguration.
