I am the Aravind K Joshi Term Assistant Professor in the Computer and Information Sciences Department at the University of Pennsylvania. My research interests include statistical machine translation, data-driven paraphrasing, and crowdsourcing.

In 2014 I was named a Sloan Research Fellow. Here is a press release from Penn about my research and the research of the two other Penn faculty members who received the award.

I was the program co-chair for EMNLP 2015 in Lisbon. I am an action editor for the new journal Transactions of the ACL (TACL). I recently finished my terms on the editorial board of Computational Linguistics, and as the Chair of the NAACL Executive Board.

My research group released PPDB, the paraphrase database, a resource with 169 million paraphrase transformation rules.

We developed Joshua, an open source decoder for statistical machine translation, which uses synchronous context free grammars, and extracts linguistically informed translation rules.

I am in my 3rd year at Penn, so I am up for reappointment. If you would like to read my reappointment materials, here they are:
