Biography

Dr Mukhopadhyay is an associate professor in the School of Computer Science at the University of Birmingham. They are primarily associated with the Theory of Computation group. My research interest is in algorithms and complexity.

In their previous avatar, Sagnik was a lecturer (Assistant professor in North American equivalence) in the Department of Computer Science at the University of Sheffield, a post-doctoral researcher at the Department of Computer Science in the University of Copenhagen in 2021, at KTH Royal Institute of Technology during 2019-2021, a post-doctoral fellow at IUUK, Charles University in 2018, in the APC group at KTH Royal Institute of Technology during 2017-2018, and a graduate student in theoretical computer science at TIFR Mumbai until August 2017.

Sagnik is a recipient of the UKRI New Investigator Award. During my PhD, they were a recipient of TCS PhD Fellowship and their PhD research work was supported by this fellowship.
