I am a research scientist at the Human Language Technology Center of Excellence and in the Department of Computer Science at Johns Hopkins University. My main research interest is machine translation, but I also like grammar correction, parsing, and other things that involve syntax.
I recently spent a year (August 2017–August 2018) on leave working with Amazon Research in Berlin.
I have helped organize the manual evaluation of the annual Conference on Machine Translation for a number of years. I was a member of the NAACL executive board for the 2015-–2016 term, and was one of the ACL 2018 area chairs for machine translation. I also used to maintain the Joshua decoder, but now I mostly work on Sockeye.
