http://swarmcontrol.net, http://www.youtube.com/aabecker5, https://sites.google.com/site/aabecker/ Aaron Becker's passion is robotics and control. Currently as an Assistant Professor in Electrical and Computer Engineering at the University of Houston, he is building a robotics lab. Previously as a Research Fellow with Boston Children's Hospital and Harvard Medical School, he implemented robotics powered & controlled by the magnetic field of an MRI, in the Pediatric Cardiac Bioengineering Lab with Pierre Dupont. As a Postdoc at Rice University in the Multi-Robot Systems Lab with James McLurkin, Aaron investigated control of distributed systems and nanorobotics with experts in the fields. His online game swarmcontrol.net seeks to understand the best ways to control a swarm of robots by a human--through a community of game-developed experts. Aaron earned his PhD in Electrical & Computer Engineering at the University of Illinois at Urbana-Champaign, advised by Tim Bretl.
