# overview
My current research focuses on the development of computational methods for the analysis, design, and operation of complex systems.  I am specifically interested in aspects of uncertainty quantification, multidisciplinary design optimization, and compositional methods for simulation-based design.  I am currently working on projects involving the development of computational methods for enabling self-aware unmanned aerial vehicles, the development of optimal algorithms for multi-information source management in design, and the development of methods for enabling correct-by-construction model-based design processes.
