  • 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.

    To facilitate the development of such bulk elemental composition instruments, I have built a unique facility at Goddard for the testing and calibration of landed gamma ray/neutron instruments. Situated out at Goddard’s Geophysical and Astronomical Observatory (GGAO), this outdoor Gamma ray Neutron Test (GNT) facility 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 the instrument from a building 200 feet away. This GNT facility is also available for use by outside collaborators.

    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.

    To facilitate the development of such bulk elemental composition instruments, I have built a unique facility at Goddard for the testing and calibration of landed gamma ray/neutron instruments. Situated out at Goddard’s Geophysical and Astronomical Observatory (GGAO), this outdoor Gamma ray Neutron Test (GNT) facility 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 the instrument from a building 200 feet away. This GNT facility is also available for use by outside collaborators.
