I am a PhD candidate in the Language Technologies Institute at Carnegie Mellon University.
I am adviced by Dr. Tanja Schultz and we try to wreck a nice beach!
I currently work on the GALE (Global Autonomous Language Exploitation) project as part of the Rosetta speech team, which also includes researchers from IBM Research and Columbia University.

Achtung: Currently, I am on leave from CMU and visiting Cognitive Systems Labs , Karlsruhe, Germany as a student researcher
