Dr. John Dannenhoffer is the principal author of the Engineering Sketch Pad (ESP), which is a computer-based system for the optimal design and analysis of complex configurations, such as aerospace vehicles.  ESP is a feature-based solid modeler that generates the fully-associative models needed for multi-fidelity and multi-disciplinary design and analysis.  A key feature of the ESP are that it is the first CAD-like system that directly provides the sensitivities needed for gradient-based optimization.  The ESP, which is available as an open-source projects, is in routine use by over a thousand users, in dozens of organizations.
