Research

My research focuses on the theory of soft materials, particularly on the study of pattern formation in continuum mechanics, including elasticity and fluid dynamics. My aim is to understand the underlying physical mechanisms that govern the behavior of soft materials, and how they can be used to improve technological applications.

In recent years, I have been particularly interested in the area of mechanical instabilities that emerge on the surface of an elastic medium. This includes exploring the formation of patterns and structures that result from the interplay of forces, geometries, and material properties. By developing a deeper understanding of these processes, I hope to contribute to the development of new materials that can be used in a wide range of applications, including energy, environment, and healthcare.
