Melissa A. Jones  |  Manager

Dr. Jones obtained her B.S. in Chemistry from Loras College in 2002. Her thesis research focused on simulating surface features on asteroids using regolith fludization techniques on NASA’s microgravity plane. She went on to pursue her Ph.D (2006) at the University of Arkansas where her graduate work focused on studying chemical and physical surface processes on asteroids as well as designing and environmentally testing a sample collector for a proposed near-Earth asteroid sample return mission, which was a collaboration with JPL. Her multipdisciplanary dissertation had a strong science and engineering interface which she ultimately decided to pursue as a career path. Dr. Jones started her career at JPL in 2006 where she spent the first 7 years pursuing opportunities to learn systems engineering. In 2013, she become the Biotechnology and Planetary Protection Group Supervisor, a group where both science and engineering have to meet to get the job done correctly.
