Dr. David Helmer, Ph.D

​​Assistant Professor

Program Manager – Johns Hopkins University Applied Physics Laboratory



Dr. David Helmer received his PhD from Stanford University in 2011, where he majored in Mechanical Engineering and focused on measurement of supersonic flows.  He worked at General Electric Global Research as a Heat Transfer Research Engineer exploring novel experimental techniques useful to informing 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 Program Manager.  David specializes in  advanced experimental methods and data processing.  He has been a part-time Assistant Professor at USMA since 2017.
