### Research interests

My research group investigates soft solids and structures under extreme deformation.

We currently focus on smart composites with multi-physics coupling (electro-mechanical and magneto-mechanical), and soft biological tissues. Extreme deformation of structures made of these soft materials result in instabilities. Traditionally instabilities are associated with structural failure, but in the case of soft solids instabilities are generally reversible and can be exploited to our advantage and implemented as an engineering design feature. We model these instabilities using mathematical and computational tools to develop a deeper understanding of their mechanics.

Our commonly used tools are nonlinear solid mechanics, continuum mechanics, variational calculus, and numerical analysis.
