Personal Bio

Dr. Omran is a faculty member at Johns Hopkins University (JHU) and at Loyola University Chicago (LUC). Omran is a member of ASME and AIAA. Omran was the Session Chair of “Nonlinear Systems II”, American Control Conference, 2011.  Omran was a distinguished speaker and keynote in International Conference and Exhibition on Mechanical & Aerospace Engineering, 2019 and 2020.  He has authored 20 U.S. patents in the field of transmission control systems, more than 40  journal and conference papers in the field of Aerospace, Dynamics and Control and is in the midst of writing his “Kinematics and Dynamics of Machines using MATLAB, Machines Are Everywhere” textbook, which Springer will be publishing. 

Dr. Omran received his PhD in Aerospace Engineering Science from Old Dominion University (ODU). After that, he worked as research scientist and collaborated with NASA and Lockheed Martin, working on enhancing the NASA Langley Research Center’s “Airspace and Traffic Operations Simulation” (ATOS) and “Aircraft Simulation for Traffic Operations Research” (ASTOR) software frameworks. He also worked with Metron Aviation and NASA to develop several up-gauging scenarios of the fleet-shifts as a trial of the JPDO to design a NextGen system that would accommodate future passenger demands, while mitigating challenging environmental aspects. 

Dr. Omran worked in industry from 2011 to 2017 as a senior control engineer at Case New Holland Fiat Industry in Illinois to design and analyze control systems for transmission and vehicle dynamics. In 2018, he returned to academia at Texas A&M University to initiate the aerospace minor courses (Aerodynamics, Flight Dynamics, Aerospace Structure and Aircraft Design) at TAMUK. In 2019 he joined LUC as a faculty member in Engineering Science in addition to working at JHU since 2020. Omran has more than 20 years hands-on experience with Dynamics and Control.
