Two PhD Openings Available

We are recruiting two PhD students (fully funded research assistant). The first position is in the area of swarm control of unmanned aerial vehicles (UAVs). The successful candidate is expected to work on a collaborative project about multiple UAV flight control for structural monitoring of wind turbines. The second position is in the area of control of renewable energy systems and microgrids. The successful candidate is expected to work on a collaborative project to develop a comprehensive control framework for power systems with varying levels of inverter-based resources. Candidates with excellent mathematical skills, control background, and relevant project experience are preferred. A master’s degree in ME, EE, or a related field is required although excellent candidates with a bachelor’s degree are also considered. Interested applicants are welcome to contact Dr. Ren via email: beibei.ren@ttu.edu.
