Dr. Walker's primary research interests lie in electric propulsion, plasma physics, and hypersonic aerodynamics/plasma interaction. He has extensive design and testing experience with Hall thrusters and ion engines. Dr. Walker performed seminal work in Hall thruster clustering and vacuum chamber facility effects. His current research activities involve both theoretical and experimental work in advanced spacecraft propulsion systems, diagnostics, plasma physics, helicon plasma sources, magnetoplasmadynamic thrusters, and pulsed inductive thrusters. He also teaches the undergraduate Jet & Rocket Propulsion course, as well as the graduate level Rocket Propulsion and Electric Propulsion courses.
