• Signals and Systems.

Professor Zadehgol’s research interests include theoretical, applied, and computational electromagnetics, with a special focus on the advancement of computational algorithms and methods for the efficient (accurate, fast, and stable) modeling of arbitrary structures (media and geometries) including electrical devices, circuits, systems, and networks. In parallel, his research pursues the advancement of signal/power integrity modeling across the frequency spectrum, from optical (100s of THz), to µ-waves and mm-waves (100s of MHz to 100s of GHz), to quasi-statics (10s of Hz). His past research includes development of methodologies for modeling of disparately multi-scaled and stochastic systems, with emphasis on computational electromagnetics, model-order-reduction, system identification, and machine learning.

A recent interest of his group has been pursuing the advancement of modeling around quantum science and engineering, including quantum electrodynamics, quantum computing, and photonics. His work has been recognized through research grants from the National Science Foundation (NSF), National Aeronautics and Space Administration (NASA), Micron Technology Inc., Schweitzer Engineering Laboratories (SEL), the IEEE TCPMT best poster-paper award, and University of Idaho's Presidential Mid-Career Award. Dr. Zadehgol is a professional engineer licensed in Idaho State.
