Robotics Research
Currently, I am employed as a visiting assistant professor at Eastern Oregon University, La Grande, Oregon. My research interests are
Swarm Robotics, Multi-Agent Systems, Physicomimetics, Distributed Robotics, Evolutionary Learning, Search Algorithms, Adaptive Learning, and Swarm Intelligence.
Currently, There are two groups of undergraduate students working together with me, the first group is simulating mobile robot behavior and the second group is working on a wheel based robot prototype. Both groups are using physicomimetics approach in their control algorithms.
