Barrett E. Koster enjoys building complex tools and solving hard problems. As a mostly-teaching professor, he has focused his research energy on student projects, which have tackled creative challenges like writing music programs, measuring rooms with sound, and testing watermelons. His current independent projects include simulating fabric in higher dimensions to study particle formation, improving automatic lip syncing using Markov models, developing a circuit simulator, and creating a time management program. While his research record is limited due to teaching obligations, he believes he could be more productive in an environment with more computer resources and collaborators.
