Research Areas

Research Interests

My research is concerned with developing predictive models that rationalize the physics at play in problems arising in natural settings and model laboratory experiments. Through the elucidation of a variety of nature’s mechanisms, my group aims to inspire and inform the design of new technologies. Iteration between observation, analog experiment and theoretical modeling is a critical feature of my research, which is interdisciplinary by nature at the cusp of fluid mechanics, flexible solids mechanics, non-linear physics, biology and design.

Taming instabilities toward functionality

Patterns in nature have a staggering regularity that contrasts with the complexity of their constituent materials. The seemingness ease with which such patterns occur suggests that they are encoded in the "blueprint of nature". They are often the result of instabilities -- traditionally seen as the engineer's nemesis. Here, we propose to tame such instabilities and harness them in fluidic systems undergoing a phase change. With this perspective, we study problems involving thin fluid films, viscous threads (3D printing), microfluidics systems, but also elastic shells, swelling and elastocapillarity.

Shape morphing/ actuation and living matter

Applications are not limited to fluids and range from reversible shape-morphing and snapping in shells to morphogenesis. Furthering our capacity to elucidate those mechanisms through an improved formalism (theory/numerics/experiments) would indeed benefit our understanding of living matter and inform the development of bio-inspired or bio-augmented technology.
