I am a PhD candidate in the Language Technologies Institute at Carnegie Mellon University.
I am adviced by Dr. Tanja Schultz and Dr. Florian Metze. We try to wreck a nice beach!
I work on accent issues in speech recognition, but I am interested in all facets of speech processing and statistical learning in general.
