I am a Machine Learning researcher in the Debating Technologies team at IBM Research. My research interests are in the field of natural language processing (NLP) focusing on stance classification, sentiment and negation analysis. Before working on text processing in the Debater team, I was a researcher in the Speech Technologies group, focusing on speech recognition, speaker recognition, speaker diarization, and emotion recognition.
Prior to joining IBM in 2009, I was a researcher in several speech processing companies: Nuance Communications, Persay Inc., Comverse, and a research engineer at SRI International.
I received my Ph.D. in Biomedical Engineering from Boston University in 1997, under the supervision of Prof. Mari Ostendorf, conducting research on acoustic modeling for speech recognition. I hold an M.Sc. in Biomedical Engineering from the Technion, Israel Institute of Technology (1992), and a B.Sc. in Physics from Tel Aviv University (1990).
