Dilmurat Azimov is a Professor of Mechanical Engineering at the University of Hawaii at Mānoa. His research focuses on space trajectory optimization, guidance, navigation and control (GNC), optimal control, and orbit determination using observations for astrodynamics applications. His expertise includes analytical solutions for optimal control problems and applying them to mission design and to the implementation of guidance, control and targeting schemes for aerospace vehicles, including unmanned aerial vehicles (UAVs).Dr. Bishop is the Vice Chancellor for Engineering at the Texas A&M System, Dean of Engineering at Texas A&M University, and Director of the Texas A&M Engineering Experiment Station. He is a full professor in the Department of Aerospace Engineering. His research interests include systems theory, guidance and control of spacecraft, navigation and estimation, with a special focus on small satellites and planetary precision landing.
