I have been always attracted by areas of knowledge that intersect more than one traditional discipline. My interests are centered on the development of digital signal processing, system modeling, and biomedical engineering tools that involve speech, audio, and acoustics. My recent research efforts have revolved around developing quantitative models that describe nonlinear effects in human speech production, and applying these physiological descriptions for the development of communication and clinical technologies. I have a BS degree in Acoustical Engineering, and MS and PhD degrees in Electrical and Computer Engineering.
