Brief Bio


Ronald S. Gamble, Jr, Ph.D. is a Theoretical Astrophysicist at NASA Goddard Space Flight Center researching the energy emission processes of relativistic jets from high-energy active galactic nuclei and their connection to Supermassive Black Hole rotations. He is currently a CRESST-II Visiting Assistant Research Scientist at NASA Goddard Space Flight Center and the University of Maryland—College Park. Accompanying this, Dr. Gamble also has seven years experience in academia as a physics, mathematics, and computational science instructor and curricula developer. His experiences span across multiple industries including higher-education, space & defense, and the Arts.


He received his Ph.D. in Theoretical Astrophysics (2017); M.S. in Condensed Matter Physics (2014) and B.S. Physics (2012) from the North Carolina Agricultural & Technical State University. While there he held a Title III HBGI Fellowship, completing the first physics-related dissertation at North Carolina A&T State University pertaining to the emission and propagation of nonlinear tensor-mode gravitational waves from colliding black holes. Dr. Gamble holds professional memberships in the National Society of Black Physicists, the National Society of Hispanic Physicists (2009-2012), and the American Physical Society (FECS, Division of Astrophysics, Division of Gravitational Physics, and the Forum on Diversity & Inclusion). He is frequently sought after by his former students for academic and career advisement and mentoring. His future endeavors involve establishing a network for mentoring undergraduate and graduate students within underrepresented STEM fields. Dr. Gamble is also an established oil/acrylic painter, graphic designer, and illustrator with 15 years of experience.
