Sir Michael Professor Edgar Choueiri 
(ASL President 2008-2014)

Professor Edgar Choueiri is Director of Princeton University's Program in Engineering Physics, and Chief Scientist and Director of Princeton's Electric Propulsion and Plasma Dynamics Laboratory (EPPDyL). He is Professor in the Applied Physics Group at the Mechanical and Aerospace Engineering Department, and Associated Faculty at the Astrophysical Sciences Dept./Program in Plasma Physics at Princeton University. He holds a PhD in Aerospace Engineering/Plasma Science (1991) from Princeton University.

He has been the Principle Investigator (PI) in charge of directing and managing more than 25 competitively selected research projects, funded by NASA, AFOSR, the National Science Foundation, and other governmental and private institutions. He has been PI and Co-PI on two space experiments onboard the Space Shuttle and the Russian scientific spacecraft APEX. Professor Choueiri's laboratory (EPPDyL) at Princeton University, a recognized center of excellence in research in the field of advanced spacecraft propulsion, has been continuously funded by NASA since he became EPPDyL's Chief Scientist in 1996.

Prof. Choueiri's main research interests are in astronautics and plasma physics, and he is the author of more than 140 journal articles, conference papers and encyclopedia articles on plasma propulsion for spacecraft, plasma physics, instabilities and turbulence in collisional plasmas, plasma accelerator modeling, space physics and applied mathematics. He has been an invited speaker at symposia and leading institutions in more than 20 countries and has advised more than a hundred graduate and undergraduate students at Princeton University. Many of his PhD students are in leading positions as research scientists in plasma physics or space propulsion. He serves as Associate Editor of the Journal of Propulsion and Power, the leading journal for spacecraft propulsion.

He is the recipient of a number of awards and honors, including the Howard B. Wentz Award for Excellence in Teaching and Scholarship and the Medal of the Order of the Cedars (rank of Knight), and was elected President of the Electric Rocket Propulsion Society, whose members include hundreds of scientists working on plasma propulsion for spacecraft in more than 15 countries. He served as the elected Chair of the American Institute of Aeronautics and Astronautics' Electric Propulsion Technical Committee (EPTC) from 2002 to 2004, the leading professional society in his field, was awarded the AIAA's distinguished service award in 2004 elected Fellow of the AIAA in 2009.

He was selected by NASA in 2004 as the winner of a competition to lead a team of NASA and academic rersearchers on a 3-year research project to develop a high-power plasma rocket system intended for the robotic and human exploration of the Moon and Mars.

Prof. Choueiri served as President of the ASL from June 27, 2008 to Januray 31, 2014.
