Research Interests
Primary Research Theme: Dynamics and Control
Research Group/Lab : Aerospace Mechatronics Laboratory
Unmanned aerial vehicles: dynamics, navigation and control of small UAVs (quadrotors, indoor airships) Multibody systems: contact dynamics, modeling, simulation, parameter identification. Dynamics, control and motion planning of mechatronic systems: legged robots, space robotic systems. Computational mechanics: contact mechanics, finite elements analysis.
Current Research Projects
-

-
Unmanned aerial vehicles (UAVs): dynamics and control, state estimation, localization, motion planning
-
Collision recovery for small UAVs
-
Active space debris removal strategies: robotic capture and post-capture maneuvering and stabilization

For More Information Regarding Her Research Projects
Postdoctoral Position Available
Professor Sharf is currently looking to recruit a postdoctoral fellow for one year, likely to be extended for another year, to work on a UAV related project. The candidate should have background in any of the following areas: UAV formation or coordinated control, coordinated path planning and collision avoidance. Ideally, the candidate should have good theoretical/numerical background but also hands-on experience of working with UAVs. Interested candidates should send their CV’s directly to Professor Sharf.
