Summary of Research

Richard works to understand problems at the interface of society and the
environment by using novel methods drawn from his background in computation,
physics, and sensors. He is particularly interested in life strategies which are
excluded by evolutionary processes and their application to problems in
agriculture. He also works to understand the layout and composition of
boundaries between natural and artificial watersheds, and how these impact water
quality and availability. The foregoing entails investigation into the formal
underpinnings of evolution, game theory, and algorithm design.
