Aaron Knoll is a senior lecturer in the field of plasma propulsion for spacecraft within the Department of Aeronautics at Imperial College London.  Aaron received his Bachelors of Aerospace Engineering (2003) and a Masters of Applied Science in Aerospace (2005) from Carleton University in Ottawa, Canada. During his undergraduate education he performed an internship with the Canadian Space Agency as part of the Software and Ground Segment from 2001 – 2002. Aaron received his Ph.D. (2010) from Stanford University, where he was involved with the research of instability driven electron transport within Hall Effect Thrusters. The focus of Aaron’s research at Imperial is toward the development of novel low power plasma propulsion technologies for small spacecraft.
