I have moved to a new position at the Ohio State University. If you need to reach me, please contact me at the following email address: williamson.413@osu.edu


I am an assistant professor in the Luddy School of Informatics, Computing, and Engineering (SICE) at Indiana University, where I am the Director of the Audio, Speech and Information Retrieval (ASPIRE) research group. I am also a part of the Data Science program, Cognitive Science program, and the Center for Machine Learning. I recently became a GT Scholar, as part of GT-IDEA.

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/enhancement, speech evaluation, and speech recognition, 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.

My work is externally supported by the National Science Foundation (NSF) through a CAREER Award and a CRII Award , and by the Toyota Research Institute

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.
