Chirag Wadhwa

I am a third-year PhD student in the School of Informatics, University of Edinburgh, advised by Mina Doosti and Myrto Arapinis. I previously obtained a bachelor’s degree in Computer Science and Engineering from the Indian Institute of Technology, Roorkee in 2023.

I am broadly interested in theoretical computer science and quantum information, with a focus on the statistical complexity of learning and testing quantum objects.
