My main research focus is in the development of computational techniques in electromagnetics. Emphasis is on modeling wave interactions with transmission lines and printed circuits for EMI/EMC applications. Our group has also been studying the applications of Lattice Gas Automata in electromagnetics modeling. On the experimental side, we have been developing new scanning probe microscopy tools for high frequency microelectronics diagnostics and failure analysis.
