Neuromorphic Computing

Biography

Fred Rothganger is a refugee from the world of Artificial Intelligence. He earned his PhD playing with robots and computer vision at the University of Illinois. After sliding into despair about the inherent ceiling of modern AI techniques, he turned to the brain for answers.

Unfortunately, Fred’s own brain is too small to understand the brain, so he hopes that machines will do it for him. His focus is on building computer tools to assemble comprehensive models. He leads the development of N2A ("Neurons to Algorithms"), a framework for expressing neural dynamics across a wide range of scales.

Fred has published in computational neuroscience, machine vision and robotics. When he gets fed up with lack of progress in the real world, he writes science fiction.
