Welcome!

I am an assistant professor in the School of Informatics and Computing at Indiana University. My research broadly addresses ways that enable computers to process, understand, and response to sound information. I have specific interests in the areas of speech separation, speech recognition, speaker identification, and music processing, to name a few, where I am interested in using these methods in real-world devices, such as cell phones, hearing aids, and robots. A combination of machine learning, signal processing, and statistical-based techniques are used.

I completed my Ph.D. in the Computer Science and Engineering department at The Ohio State University, under the supervision of Prof. DeLiang Wang. Prior to that, I was fortunate to be a Member of the Engineering Staff at Lockheed Martin for a few years. I received a Masters of Science degree from the Department of Electrical and Computer Engineering at Drexel University and a Bachelor's degree from the Department of Electrical and Computer Engineering at the University of Delaware.
