About

I am a graduate student at the Georgia Institute of Technology in the School of Electrical and Computer Engineering. Previously, I attended Washington University in St. Louis and Vanderbilt University where I received a Bachelors of Science in Biomedical Engineering and completed graduate studies in Hearing and Speech Sciences, respectively. I received a Masters of Science in Electrical and Computer Engineering from Georgia Tech in August 2011 and continue to work towards a Doctor of Philosophy.


My research interests are generally in the areas of signal processing and biomedical engineering applied to the human auditory system. I am interested in developing innovative, physiologically-inspired techniques for cutting-edge amplification solutions. Currently, I am working under the advisement of Christopher J. Rozell, where I am investigating the use of sparse approximations and low-power audio processing techniques for novel, non-linear hearing aid and cochlear implant systems. I am supported by the Department of Defense through the National Defense Science and Engineering Graduate Fellowship (NDSEG) Program, the National Science Foundation's Graduate Research Fellowship Program (GRFP), and the Georgia Tech Presidential Fellowship.
