I am a research scientist at the Human Language Technology Center of Excellence and in the Department of Computer Science at Johns Hopkins University. From August 2017 through August 2018 I am on leave from Hopkins, working with Amazon Research in Berlin. My main research interest is machine translation, but I also like grammar correction, parsing, and other things that involve syntax.
I have once or continue to maintain the Joshua decoder, co-advise (with Ben Van Durme) Keisuke Sakaguchi, and co-organize the annual Conference on Machine Translation. I was a member of the NAACL executive board for the 2015-–2016 term.
