Brief Bio

During my career I have had great experience applying nuclear instrumentation technology to space science missions, beginning with my involvement in the extremely successful Swift Gamma Ray Burst Explorer launched in 2004. I fully participated in the design, fabrication and calibration of the Swift Burst Alert Explorer (BAT) gamma ray imager as well as its integration with the Swift spacecraft and the following environmental testing. I also actively participated in BAT flight operations and data analysis after launch.

My scientific interests have since broadened to include the study of the origin and evolution of the planets. Since 2007 I have been developing nuclear detector systems for planetary science applications. My knowledge of gamma ray, neutron and x-ray detectors used for astrophysics transferred easily to the gamma ray neutron technology used for determining the bulk elemental composition of the surface and near sub-surface of planetary bodies. Upon Dr. Jacob Trombka's retirement in 2009, I became the leader of a nuclear planetary science instrumentation program at Goddard. I have developed new flight instrumentation capabilities within the group by managing both NASA and internally-funded instrument development programs to produce an active gamma ray-neutron elemental composition measurement instrument for landed Planetary Science applications. I have worked in close partnership with Schlumberger Technology Corporation to adapt their Pulsed Neutron Generator (PNG) used in the oil industry to space flight applications. This instrument technology forms the basis of the Dragonfly Gamma ray Neutron Spectrometer (DraGNS) aboard the selected Dragonfly mission to explore the surface of Titan. Dragonfly will launch in 2027 and will arrive at Titan after 2034. This technology is also being tuned to the needs of a lunar science elemental composition instrument through the development of the Bulk Elemental Composition Analyzer (BECA) funded through the Development and Advancement of Lunar Instrumentation ( DALI) program.

To facilitate the development of such bulk elemental composition instruments, I have built a unique facility near Goddard for the safe testing and calibration of instruments that emit hazardous radiation such as the high energy neutrons from a PNG. Situated out at Goddard’s Geophysical and Astronomical Observatory (GGAO), this outdoor Gamma ray Neutron Test Facility (GNTF) allows users to safely operate high-energy gamma ray and neutron radiation instruments on top of large granite and basalt samples. With underground power and Ethernet feeds to the test location, experimenters can safely operate their instruments from a building 60 meters away. This GNTF is available for use by outside collaborators.
