About me

I am a Postdoctoral Research Fellow at Tampere University, specializing in Answer Set Programming (ASP), Automated Reasoning, and Constraint Programming. My research primarily focuses on advancing ASP techniques to enhance AI problem-solving, particularly in optimization and knowledge representation. With a strong background from Aalto University and Sharif University of Technology, I am also involved in projects related to Explainable AI, where I strive to make AI systems more transparent and interpretable.
 

Responsibilities

As a Postdoctoral Research Fellow, I develop cutting-edge algorithms for Answer Set Programming (ASP) and its applications in AI planning and optimization. I also mentor graduate students, involve in research collaborations, and actively participate in publishing and presenting research findings at major AI conferences.

Fields of expertise

My expertise centers on Answer Set Programming (ASP), with additional strengths in Automated Reasoning, SAT-based Planning, Constraint Programming, and Knowledge Representation. I have developed innovative ASP-based techniques that are crucial for solving complex AI problems, including applications in Explainable AI.

Top achievements

Best Paper Award at the 39th International Conference on Logic Programming (ICLP 2023) for work on ASP.
Development of efficient translations of ASP into SAT and Integer Programming.
Significant contributions to Explainable AI, recognized through multiple publications.

Main positions of trust

Program Committee Member: European Conference on Artificial Intelligence (ECAI), AAAI Conference on Artificial Intelligence, and International Conference on Automated Planning and Scheduling (ICAPS).


Invited Lecturer: Sharif University of Technology, teaching courses on Artificial Intelligence and Compiler Design.

Mission statement

My research aims to push the boundaries of Answer Set Programming (ASP) and its integration into broader AI systems. I also focus on employing ASP particularly in the context of Explainable AI, where making AI systems more interpretable and transparent is crucial.
