Hedayat (Heddy) Zarkoob

I am a PhD student in computer science at the University of British Columbia (UBC) under supervisions of Prof. Kevin Leyton-Brown and Hu Fu. I am interested in using cutting-edge AI tools to improve peer evaluation and grading systems. I am also generally interested in Algorithm Game Theory, Mechanism Design, and Theory of Computer Science. I am affiliated with the Laboratory for Computational Intelligence (LCI) and the Algorithms Lab.

Before joining UBC, I received my M.Sc. in computer science under the supervision of Prof. Andrei Bulatov at Simon Fraser University.


- I am very lucky to be one of the AAAI 2021's Workflow Chairs.
- You can watch my talk at AAMAS 2020 about incentivizing accurate grading in peer grading systems from here.


I am leading a project on redesigning and re-implementing a partially automated web-based peer grading system called Mechanical TA (MTA). The key difference from other peer-grading systems is that MTA uses TAs to perform selective spot-checks and thus incentivizes high-quality grading. Here is a link to an early version of the application.
