My main research interests are in the analysis and computer-aided verification of analog circuits and communication systems. They include the application of numerical techniques to RF circuits and systems, theory and formulations for analyzing specialized dynamics in practical systems, understanding and predicting time-varying and nonlinear noise phenomena, automated macromodelling and system-level verification using appropriate levels of abstraction. Research in these areas is important for enabling future tools for better analog design, especially for portable and wireless communications. I am also interested in design and verification techniques for optical communications and integrated electro-optics, and in novel optoelectronic systems and communication schemes.
