Research Description

Many ordinary materials such as grains, foams, pastes, paper, and thin shells, easily yield to gentle deformations, but their responses are often unpredictable and complex. For example, grain flows are prone to jamming and thin shells tend to buckle. Dr. Feitosa’s research focuses on understanding the origins of such complex behavior with the goal of preventing undesirable catastrophic failure while handling such soft materials and exploiting their complex behavior for sophisticated technological applications.
