Dr. Julian Edward

Dr. Edward's main area of research is analysis and partial differential equations. He has studied the spectral and inverse spectral properties of Steklov eigenvalues on bounded domains, and the spectral/scattering theory of Schrodinger operators on unbounded Euclidean domains. He has also studied the spectral properties of Jacobi matrices.

He is collaborating with political scientist Keith Dougherty on topics in voting theory.

His main area of research at the moment is in control theory, in collaboration with Louis Tebou in this deparment.
