Greg Ojakangas, Ph.D.

Associate Professor of Physics

Dr. Ojakangas’ research has involved the orbital and volcanic histories of the moons of the solar system, the formation of the solar system, planetary ring dynamics, computer modeling of the human-made population of debris in orbit about the earth, and the rotational and orbital history of the earth-moon system as recorded in the geologic record. He was a finalist in NASA’s astronaut selection program, he is an asteroid discoverer, and an inventor in the field of robotics. His current research involves computational neuroscience and brain-machine interfaces, and he is a consultant for NASA’s orbital debris program. He also continues to lead groups of students in experiments aboard NASA’s reduced gravity “Weightless Wonder” aircraft.
