I am a post-doctoral researcher at Allen Institute for AI, Seattle. I am affiliated with the Mosaic team and I frequently collaborate with other teams like AllenNLP and Aristo. Prior to this, I was a doctoral student at Computer and Information Sciences at the University of Pennsylvania (2017-2019) and at the University of Illinois, Urbana-Champaign (2012-2016), under Prof. Dan Roth. I have a bachelor's degree from Amirkabir University of Technology, Tehran Polytechnic (2008-2012). I was greatly fortunate to work with Prof. Hamid Sheikhzadeh during my undergraduate studies.

Research Themes

My research focuses on the computational foundations of intelligent behavior, through the lens of natural language. My goal is to explore the different ways in which we can develop and evaluate systems that understand and reason with (and about) natural language in different contexts. I mostly identify with natural language processing (ACL, NAACL, EMNLP) and artificial intelligence communities (AAAI, IJCAI) and, to some extent, with the machine learning community (NourIPS, ICML).

Here are several themes I am interested in:
