Current Projects


Mars Atmosphere and Volatiles EvolutioN (MAVEN)

Mars

Primarily focused on the upper atmosphere of Mars using teh in-situ observations from teh Neutral Gas and Ion  Spectrometer (NGIMS)

MAVEN , launched in 2013 began science observation in 2014 and continues the major science mission through end of 2020. Some changes to the science mission will occur at the end of 2020 when the periapsis targeting will change

Positions/Employment


Research Associate

University Maryland College Park - NASA Goddard

January 2014 - Present

 MAVEN NGIMS Scientist and operations. 


Postdoc Researcher

University of Virginia - Charlottesville, VA

January 2013 - January 2014

 Primary Field of Research: Seasonal variations of the plasma in Saturn’s inner magnetosphere between the main rings and Enceladus through analysis of Cassini Plasma Spectrometer data. Assist with teaching duties of the applied mathematics course Ordinary Differential Equations, including teaching once a week quiz and review section, and hold 4 hours a week for student support.


Graduate Research Assistant

University of Virginia - Charlottesville, VA

July 2007 - January 2013

 Advisor: Robert E. Johnson. Primary Field of Research: Seasonal variations of the plasma in Saturn’s inner magnetosphere between the main rings and Enceladus through analysis of Cassini Plasma Spectrometer (CAPS) data. My graduate work used the CAPS instrument; starting with the raw data converting it to numeric form, and using MATLAB to determine plasma parameters (density, temperature and velocity. In doing so I worked primarily on some of the noisiest features in Saturn’s magnetosphere, the region between the main rings and Enceladus. Assisted with teaching duties of the applied mathematics course Ordinary Differential Equations, including teaching once a week quiz and review section, and holding 4 hours a week for student support.
