Research Interests
My research is focused on evolutionary algorithms for the automatic design of fuzzy logic controllers. I am further interested in autonomous agents and adaptive behavior in complex environments. I developed a learning method for fuzzy controllers using messy genetic algorithms. The design method evolves an obstacle avoidance and goal point reaching behavior for a mobile robot. I received my Ph.D. in physics at the Institute of Applied Physics at the University of Kiel. Currently I was working as a postdoctoral researcher at the Computer Science Division at the University of California, Berkeley. I was administrator of the Berkeley Initiative in Soft Computing (BISC) directed by Prof. Lotfi Zadeh. I worked on flight mode switching and fuzzy controller design for autonomous small size helicopters. My current research interests are dynamical systems approach to behavior based robotics, UAV-UGV cooperation, probabilistic map building, path planning with evolution strategies and intelligent data analysis. I was a senior researcher in the Berkeley Aerobot (BEAR) project which is concerned with the control design for an autonomous aerial robot, hybrid control schemes, vision based landing and UAV-UGV cooperation. I am currently involved in the Intelligent Service Robot project.
