Research

My research focuses on nonlinear dynamics and vibrations with applications to wind turbines, granular materials, systems with noise, metamaterials and metastructures. In addition, I am interested in using machine learning algorithms to forecast nonlinear system behavior, such as wind turbine power output and granular surface response during robotic locomotion.
