I spent about ten years at AT&T Bell Labs or AT&T Labs - Research (1995-2004), where, in the last four years, I served as the Head of the Speech Algorithms Department and as a Technology Leader, overseeing research projects in machine learning, text and speech processing, and the design of general algorithms.

I joined the Courant Institute in the Summer of 2004 as a Professor of Computer Science. In 2004, I was a Visiting Professor at Google Research for a full Semester where I worked on several machine learning and algorithmic research projects. Since then, I continue to work at Google as a Research Consultant.

My current topics of interest are machine learning, computational biology, and text and speech processing.
