Dr David Helmer Assistant Professor Assistant Professor, Program Manager - Johns Hopkins University Applied Physics Laboratory Civil and Mechanical Engineering david.helmer [at] westpoint.edu About Education Research & Publications Dr. David Helmer received his BS in Mechanical Engineering from the Johns Hopkins University (2006), and his MS (2008) and PhD (2011) from Stanford University. He majored in Mechanical Engineering and his graduate research focused on measurement of supersonic flows. He worked at General Electric Global Research as a Heat Transfer Research Engineer, primarily focusing on experimental research to inform jet engine cooling design. While at GE, he volunteered as an instructor at USMA. David subsequently worked at the Boston Consulting Group before joining the Johns Hopkins University Applied Physics Laboratory, where he is currently an Assistant Group Supervisor for a team focused on Human-Machine Engineering. David specializes in advanced experimental methods and data processing. He has been a part-time Assistant Professor at USMA since 2017.
