Dr. Mark Happel
Mark D. Happel is the Supervisor of the Data Science and Machine Learning Section in the Air and Missile Defense Sector (AMDS) of the Johns Hopkins University Applied Physics Laboratory (APL), where he performs machine learning, statistical pattern recognition, and signal processing research and development tasks. His recent projects have focused on pattern classification in time series data, distributed reinforcement learning, and infrared video processing.
He is currently an instructor in the JHU’s Engineering for Professionals (EP) programs. Prior to this, he was an associate professorial lecturer in computer science at the George Washington University, where he taught both graduate-level and undergraduate-level artificial intelligence and machine learning courses for 10 years.
Before coming to APL, Happel performed science and technology policy research at the RAND Corporation and both neuroscience and artificial intelligence research at the MITRE Corporation. He also developed real-time, safety-critical jet engine control software at GE Aircraft Engines and performed digital hardware design and test at Northern Telecom, Inc. His first professional experience was as a nuclear-trained submarine officer in the U.S. Navy, serving as the Reactor Controls Officer, Sonar Officer, and Weapons Officer onboard USS PHOENIX (SSN702).
Happel earned a BSEE degree in electrical engineering from the U.S. Naval Academy; an MSE degree in electrical engineering from the University of Central Florida; and a DSc degree in computer science from the George Washington University.
