Diana Bull is a technical staff member in the Water Power department at Sandia National Laboratories, where her  main thrust of her research is focused on promising developments to alter the cost of energy for Wave Energy Converter (WEC) devices. Thus her work focuses on developing numerical models to predict the performance of various WEC designs as well as the subsystems that are critical to realizing ocean deployed designs.  These subsystems include the anchor and mooring solutions as well as the power conversion systems.  She joined Sandia in 2011 with prior experience in designing point absorbing wave energy converters for Ocean Power Technologies, Inc. She developed and led the experimental test program at OPT which encompassed optimal profile design, power take-off characterization, validation testing, and survival testing. During her tenure at OPT she contributed to the development of multiple ocean deployed WECs. She has a Bachelor’s degree in Physics from Vassar College and a Master’s degree in Physics from Cornell University.
