I am a third-year PhD candidate at ISTA under the supervision of Krishnendu Chatterjee. My research interests include theoretical computer science broadly. More specifically, I am interested in Program Analysis, Model Checking and Automata Theory.
Prior to joining ISTA, I completed my bachelor's degree in Pure Mathematics and Computer Science at the Ferdowsi University of Mashhad in Iran.
