My research group studies soft matter physics in the lab. We are interested in the wrinkling, crumpling, and folding of thin elastic sheets, the arrangements of solid particles in a sludge, and the rapid motions of liquids due to the surface tension that holds droplets together. These scenarios all feature soft, easily deformed materials that are common in nature and industry. Our goal is to uncover the fundamental principles that govern their behavior [1]. 

A second related thread asks what kinds of information can be retained in disordered materials, such as amorphous solids or even crumpled sheets. Remarkably, many ordinary materials retain physical "memories" of their past [2]. We are using these findings to build mechanical spring networks that can store and process information. 

If you are interested in getting involved in this research, please get in touch! We currently have openings for J-Term 2026, Summer 2026, and beyond.
