     I started my work in space plasma physics at Saint John's University [Collegeville, MN] while working on my senior thesis [Advisor:  J. Crumley].  My thesis, titled:  A Theoretical Approach to Analyzing the Size and Shape of Solitary Waves, examined the possible shapes of electrostatic BGK electron phase-space holes assuming a Gaussian potential.  I was accepted into the graduate program at the University of Minnesota and participated in a summer research fellowship prior to the start of term continuing my work on solitary waves.  I worked for C.A. Cattell, J. Crumley's former doctoral advisor.

    I started to officially work for Dr. Cattell after my first year of course work on waveform observations in and around collisionless shock waves.  I was appointed an RA for my second year as a graduate student and won the NASA Earth and Space Science Fellowship, which funded my work from Sep. 2007 through May 2010.  I applied for both the NASA Postdoctoral Program and the Living With a Star Heliophysics Postdoctoral Fellowship Program in early 2010.  I was awarded a fellowship for the later, but was later offered a permanent position as a civil servant at NASA, which I accepted.  I won the Dr. Leonard F. Burlaga/Arctowski Medal Fellowship in the summer of 2010 to fund the rest of my graduate career.

    I defended my dissertation, titled:  The microphysics of collisionless shocks, in Sep. 2010.  Three days later, my fiance and I drove to Maryland from MInnesota to start my new career at NASA.

    I continue to work on wave-particle microphysics and have helped with updating the calibration [in collaboration with Berkeley SSL] of an electrostatic analyzer on the Wind spacecraft.

     

    Research Interests

    Large amplitude whistler mode waves in the radiation belts

     I am interested in the properties of large amplitude whistler mode waves in the terrestrial radiation belts because they may play important roles in global radiation belt dynamics.

    Energy dissipation in collisionless shocks

     Collisionless shock waves are a ubiquitous phenomena in space.  They are observed in situ around planets in our solar system and in front of transient solar eruptions called coronal mass ejections.  Collisionless shocks are thought to produce some of the highest energy cosmic rays and are known to be efficient accelerators of particles in our solar system.  Their capacity to accelerate particles and induce large magnetic effects in both the terrestrial magnetic field and our power grids make collisionless shocks a topic of considerable interest.

    Shock waves are the result of a process called nonlinear wave steepening that has reached the point where the steepening is balanced by some form of energy dissipation.  In a collisional fluid (like our atmosphere), energy dissipation is accomplished by irreversibly transferring the bulk kinetic energy of the flow into random kinetic energy (i.e. heat) through binary particle collisions.  In a collisionless medium, this type of energy dissipation cannot limit wave steepening.

    One of the theorized energy dissipation mechanisms is anomalous resistivity, due to wave-particle interactions.  Here, the waves create effective collisions with the particles involved in creating the currents in the ramp of a collisionless magnetized shock wave.  These anomalous collisions limit the current (i.e. relative drift between electrons and ions), thus limit the wave steepening.

    Other forms of energy dissipation are thought to occur, including wave dispersion, particle reflection, and reversible macroscopic effects.  I am also interested in particle reflection and dispersive effects in collisionless shock waves.

    Wave-Particle Interactions

    Wave-particle interactions is a generalized way to express the study of energy/momentum transfer between electromagnetic fields and charged particles.  I study these processes by examining data from instruments that measure electric and magnetic fields combined with data from particle detectors.  Using these data, in addition to theory, I can infer and sometimes definitively show evidence of wave-particle interactions.

    These processes are important, as they are thought to play a role in:  (1) coronal heating; (2) solar flare particle acceleration; (3) particle acceleration at collisionless shocks; and (4) particle heating at collisionless shocks.

    Current Projects

    Wind Spacecraft

     I work on the following projects related to the Wind spacecraft:
    1)  I continue to write/update IDL libraries used to analyze and calibrate data from the Wind 3DP, MFI, and WAVES instruments
    2)  I work to keep the Wind spacecraft wikipedia page updated at:
    http://en.wikipedia.org/wiki/WIND_(spacecraft)
    3) I work to keep the Wind spacecraft home page updated at:
    http://wind.nasa.gov
    4)  I continue to publish results using data from the Wind spacecraft.


    THEMIS Spacecraft

    1)  Contribute to and help to update TDAS software
    2)  Use THEMIS data for studies of collisionless shock waves and processes
