Brian Armstrong

A graduate of both MIT and Stanford, Dr. Armstrong was attracted to UWM because of Milwaukee’s rich industrial history. His lifelong drive to implement technical research in pragmatic applications has led to advances in medicine (such as motion tracking to improve MRI imaging), robotics and Doppler radar. Dr. Armstrong enjoys getting students personally involved in projects and relies heavily on Socratic instruction methods.
