I carry out a wide variety of research in planetary and space physics ranging from studies of planetary compositions, solar and magnetophysics, and the development of instrumentation and analysis techniques needed to carry out these studies.  Areas of specific expertise, capabilities, and projects are given below.

  • Research work in lunar and planetary science using techniques of orbital nuclear spectroscopy:  I have carried out and continue to conduct lunar science studies using global composition maps from Lunar Prospector (LP) gamma-ray and neutron data, lunar polar hydrogen abundances using LP neutron data, and lunar gas release events using LP alpha particle data.  I am currently working on studies of Mercury's surface composition using data from the MESSENGER Gamma-Ray and Neutron Spectrometer.  I am conducting and participating in studies of the asteroids Vesta and Ceres using data from Dawn's Gamma-Ray and Neutron Detector (GRaND). I have participated in studies of surface composition for Mars and the asteroid Eros using nuclear spectroscopy data.
  • Research work on instrument development for future planetary surface instrumentation:  I have carried out instrument design, development, and experimental testing studies for planetary surface gamma-ray and neutron detectors. Specific projects have included instrument developments and experiments to validate planetary rover neutron spectrometers, build miniature nuclear spectrometers for planetary surface-based applications, and develop a miniature high-purity germanium gamma-ray detector for planetary science applications.
  • Research work in magnetospheric and solar physics:  I have carried out magnetospheric science studies using data from the Los Alamos designed Magnetospheric Plasma Analyzer experiment during my postdoc tenure, and I am currently conducting solar and magnetospheric physics studies using data from the MESSENGER Neutron Spectrometer as well as applicable data from other MESSENGER instruments and spacecraft.
