About Me
I am a Machine Learning Scientist at Amazon in Berlin. Before joining Amazon in 2013, I was a postdoc at the Saarland University MMCI Cluster of Excellence working with Ivan Titov. Our project on inducing multilingual semantic representations received a Google research award. Before joining Ivan's group in July 2011 I was a postdoctoral fellow at the Johns Hopkins University Center for Language and Speech Processing working with Chris Callison-Burch.
I received my Ph.D. in Computer Science in late 2009 from the University of Illinois at Urbana Champaign where my adviser was Dan Roth. I spent two summers (in 2006 and 2007) as a intern at Microsoft Research Redmond working with Michael Gamon.
My research interests are machine learning and natural language processing. More specifically, I am interested in weakly supervised learning problems in NLP, computational semantics, and machine translation (particularly, for low resource languages).
Please, see my CV for more details.
