BRIEF STATEMENT<\/strong><\/p>\n\n\n\n

My research focus is on the development of digital signal processing, system modeling, and biomedical engineering tools that involve speech, audio, and acoustics. My recent 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. Developing biologically-inspired technology is becoming a new direction in modern engineering. Evolution has fine-tuned living things for billions of years, giving them many of the properties – efficiency, strength, flexibility – that we engineers love.<\/p>\n\n\n\n
