I study human expression. My research explores expression-driven systems with the following three goals: 1) discovering how people perceive and produce human expression, 2) developing machine models for human expression and embodied interaction, and 3) validating the resulting models in the context of applications.
I focus on applications and systems which enhance a person’s creative, expressive capabilities, enable novel human interaction with physical systems, or promote health and wellness by leveraging the the bidirectional relationship between human wellness and expressivity. I’m interested in all modalities of human expression; however, much of my work has a sonic, linguistic, or kinetic element. I believe that these modalities are under-explored in comparison with the visual realm. I’ve also had training in music and dance, and see many opportunities for interdisciplinary discovery and creative collaboration across the computer science, engineering, linguistics, communication, and the arts. See my research page for details about my projects, and see my interactive art page for a summary of my creative projects.
I worked in industry and academia on various research and development projects for over 20 years before returning to school to study for my PhD. See my CV for project highlights and a summary of my work history. I studied Computer Science at the University of Illinois, advised by Prof. Karrie Karahalios and Prof. Mark Hasegawa-Johnson.
