He has served as Associate Editor of the AIAA Journal of Guidance, Control, and Dynamics, the AAS Journal of the Astronautical Sciences, and the journal Celestial Mechanics and Dynamical Astronomy. Professor Hall has advised nine Ph.D. students and more than 40 M.S. students. Several of these former students are senior field grad officers in the U.S. Air Force; one is a NASA Astronaut; and several are dynamics and control experts at NASA Goddard Space Flight Center. Professor Hall is currently advising three Ph.D. students and three M.S. students, and employs several undergraduate students in the Space Systems Simulation Laboratory. Dr. Hall has published more than 100 technical papers on various subjects in dynamics and control. He earned his B.S. in Aerospace Engineering at Auburn University, M.S. in Systems Engineering at the Air Force Institute of Technology, and Ph.D. in Theoretical and Applied Mechanics at Cornell University.
