I’m Sajad Ebrahimi, an M.A.Sc student in Computer Engineering at University of Guelph. My research has been focused on Information Retrieval where I have worked on the Generative Ranking, Query Performance Prediction (QPP), and Reviewer Assignment Problem (RAP). I am working at the LS3 under the supervision of Dr. Ebrahim Bagheri and Dr. Fattane Zarrinkalam. Prior to that, I worked under the supervision of Dr. Behshid Behkamal at Ferdowsi University of Mashhad.
