Research Statement

My research lies in the area of model reduction, whose primary goal is to replace large-scale dynamical systems with lower dimensional dynamical systems having as near as possible the same input/output response characteristics as the original.

In contexts where the input/output characteristics are primary, the resulting reduced model can then be used to replace the original model, potentially as a far more efficient component within a larger simulation.

This research area is highly interdisciplinary in character and has a large overlap with other areas of mathematics and scientific computing, such as numerical analysis, systems and control theory, and optimization. It has found immediate application in diverse areas of the physical sciences and engineering including signal propagation and interference in electric circuits; (PDE) constrained optimization; uncertainty quantification and inverse problems.  I have focussed on both theoretical and computational aspects of model reduction as well as their application in real-world problems.

However, the methods and theory I develop are not specific to a particular application; rather they apply to a wide range of problems.
