Alan H. Barr

Professor Alan H. Barr is a Professor of Computer Science at the California Institute of Technology and a pioneer in the development of mathematical and computational methods for computer graphics and scientific modeling. His research spans three interconnected areas: mathematical simulation techniques for computer graphics, the development of computational methods for studying biophysical behaviors and structures, and the application of advanced computing technologies to healthcare and medical device innovation. A significant portion of Professor Barr’s work focuses on the mathematics of computer graphics, including level set methods, differential geometry, and surface modeling, which have become foundational tools in modern graphics and visualization. Beyond graphics, he has applied computational modeling to developmental biology, molecular systems, and medical imaging, contributing to areas such as automated biological tracking, diffusion tensor MRI analysis, and virtual healthcare systems. He has also collaborated with researchers at NASA’s Jet Propulsion Laboratory on computational approaches to mission design using the InterPlanetary Superhighway. Across all these domains, his work emphasizes the creation of new mathematical frameworks and computational techniques that enable novel applications in the physical and life sciences.
