Professor Chessa's research interests are in the area of computational solid mechanics (CSM) and computational fluid dynamics (CFD). Primarily, he is interested in the development and implementation of advanced numerical methods towards mechanics problems that are seen as difficult in the context of the currently available methods. The majority of his work has been in the area of finite element methods and the development of extended finite element methods (X-FEM). He has developed methods that model multiphase flows, fluid structure interaction and solidification problems without remeshing while retaining high fidelity at the moving interfaces. Also, he is interested in the use of enriched and multiscale methods as well as coupling these methods to molecular dynamics models to aid in the design of advanced materials such as ultrahigh temperature ceramic composites, nano-phase composites and nanostructures.
