RESEARCH INTERESTS

My areas of interest include mathematical modeling and computational physics, numerical solution of differential equations
and boundary value problems, scattering theory, acoustic and electromagnetic propagation modeling.  
I am also interested in array signal processing, matched field processing and data analysis.
