Career arc

Dr. Maloney earned his PhD at Georgia Tech under Prof. Glenn S. Smith, where he developed foundational FDTD techniques for antenna analysis. He went on to spend 25+ years across academia, defense, intelligence, and commercial industry — culminating in roles as Chief Scientist at the Georgia Tech Research Institute (GTRI) and co-founder of the engineering practice at Compass Technology Group.

Today he leads Marietta Research Solutions as Principal Engineer and Technical Director — bringing 30+ years of computational electromagnetics expertise directly to the clients who need it.
