Jonathan M. Cameron, Ph.D.
Dr. Jonathan CameronJonathan M. Cameron received his B.S. degree in Mechanical Engineering in 1979 and his M.S. in Engineering Science and Mechanics in 1980, both at Georgia Institute of Technology. In 1981, he was employed by Jet Propulsion Laboratory (JPL) in Pasadena, California, where he was involved in spacecraft and ground vehicle control research including path planning for robotic vehicles. In 1988, he left JPL on an educational leave of absence to pursue a Ph.D. in Mechanical Engineering at Georgia Institute of Technology under the direction of Professor Wayne J. Book.  He completed his Ph.D in December, 1993. From then until 1995, he was employed by the College of Computing at Georgia Tech to work with Prof. Ronald Arkin as a research scientist investigating multiagent robotics. In July of 1995, he returned to JPL and is now a member of the Autonomy and Control Section where he is working on several advanced space exploration concepts. His research interests include robotics, dynamics, kinematics, controls, and software development.

Dr. Marco Quadrelli is a Senior Member of the Technical Staff in the Guidance and Dr. Marco QuadrelliControl Section at JPL. He received a Laurea/M.S. in Mechanical Engineering from the University of Padova (Italy) in 1987, a M.S. in Aeronautics and Astronautics from M.I.T. in 1992, and a Ph.D. in Aerospace Engineering/Computational Mechanics from Georgia Tech in 1996. He has worked in the Italian aerospace industry and has been a visiting scientist at the Harvard-Smithsonian Center for Astrophysics and at the Institute of Paper Science and Technology in Atlanta. His flight project experience includes the Cassini-Huygens Probe Decelerator Design, the Deep Space One (DS-1) dynamics analysis and testing, the Mars Aerobot Test Program, the Mars Exploration Rover (MER) Entry, Descent, and Landing, the Space Interferometry Mission, the Autonomous Rendezvous Experiment, the Laser Interferometer Space Antenna (LISA), the Mars Express, the Jovian Icy Moons Orbiter (JIMO), and the Mars Science Laboratory (MSL). His research experience in dynamics and control includes: tethered spacecraft; inflatable spacecraft; computational micromechanics; decelerator and scientific balloons; fuel slosh modeling and dynamics; flexible multibody dynamics, formation flying of distributed spacecraft, and active control of deployable structures. His current research interests are in innovative concepts of adaptive structures for space applications. Specifically, he has been involved in integrated modeling and control of large space structures, such as large apertures in the microwave, visible band and in the sub-mm band, and has conducted research on formations of tethered interferometers as stable platforms for far-IR and sub-mm astronomy, on the modeling, metrology, control and estimation of 25 meter class gossamer apertures in GEO, and on inflatable apertures in LEO for microwave-range remote sensing of soil moisture and salinity. He is also interested in the infusion of concepts of theoretical physics into space engineering applications. He is a Senior AIAA Member, and serves as Associate Editor of the International Journal of Computer Modeling in Engineering Sciences. He has written 15 refereed Journal publications, and over 40 conference papers. Selected publications in the area of distributed spacecraft are below.
