My research is primarily in the study of continuum mechanics, mathematical physics and partial differential equations. In particular, I study theoretical and mathematical aspects of continuum mechanics, concentrating on non-classical models including Cosserat rods and gradient continua. The models I’ve worked on go beyond traditional theories of elastic and viscoelastic Cauchy continua, offering the potential to describe complex phenomena—such as fracture or the combined stretching, bending, and twisting of thin rods—in a simple and geometric manner. Moreover, they lead to the creation of new and intriguing partial differential equations.
