Biography

Dr. Bravo is a Senior Aerospace Engineer at the Army Research Directorate of the US Army Research Laboratory. His work involves the development of high fidelity physics based models enabling detailed investigations of complex engine processes including spray breakup, chemically reacting flows, and particle-laden turbulence relevant to Army Aviation. He leads several research efforts in partnership with academia, industry, and cross-service agencies that span basic and early applied research in propulsion sciences. He is an Associate Fellow of the American Institute of Aeronautics and Astronautics (AIAA), member of American Physical Society, Combustion Institute and the American Society of Mechanical Engineers. He holds an appointment as an adjunct Professor of Aerospace Engineering at the University of Maryland as well as Chair of Modeling & Simulation at the Propulsion and Power System Alliance fostering collaborations within government agencies. At ARL, he also leads a DoD Workforce Development Program focused on mentoring STEM candidates in computational physics and supercomputing to address Army critical challenges. He is the recipient of multiple prestigious awards, that have brought in >$15 Mill in funds, including the HPCMP Frontier, OUSD ARAP award, and the OSD SERDP award employing exceptional supercomputing resources towards the development of next generation computational fluid dynamic and fluid structure interaction models.

Dr. Bravo received his PhD degree in Mechanical Engineering from the University of Maryland, College Park in 2013. Subsequently, he worked at ARL first as a post-doctoral research fellow and currently as a technical staff member. He has authored over 100+ research articles, delivered 30+ talks, including 2 plenary talks, and 1 patent
