Dr. Tamitha Skov Academic Experience

Graduate Researcher, University of California Los Angeles, Institute of Geophysics and Planetary Physics and the Department of Earth and Space Sciences, Space Physics Group,

1996-2002
Supervision and mentoring:

  • Acted as a mentor and provided supervision of graduate and undergraduate students in numerical modeling of flux ropes in the solar wind at 0.7 AU and 1 AU, 1999-2003.
  • The graduate level work led to an application of the modeling technique in conjunction with Faraday rotation estimates of the interplanetary magnetic field and solar wind velocity, which resulted in a successful doctoral dissertation

Other Contributions:

  • Developed synoptic ICME model and spatial mapping algorithm that inverts multiple spacecraft observations of ICMEs (having flux rope and non-flux rope geometries) and places the results in spatial context with numerically interpolated solar wind parameters within a 2D spatial grid to facilitate interpretation of complex, multi- spacecraft data.
  • Revealed connection between magnetic cloud orientation over the solar cycle and the orientation of the Sun’s streamer belt neutral line and global polar field through statistical analysis of the 11-year Pioneer Venus Orbiter (PVO) dataset. The results of this study have allowed a better characterization and prediction of geoeffectiveness of transients from magnetic field observations of the solar surface.
  • Published dissertation entitled, “The Three-Dimensional Structure and Solar Origins of Interplanetary Coronal Mass Ejections”Undergraduate Student Researcher, University of California Los Angeles, Institute of Geophysics and Planetary Physics and the Department of Earth and Space Sciences, Space Physics Group, 1993-1996

Selected Contributions:

  • Ground-test calibrations of tri-axial fluxgate magnetometer flight experiment aboardCassini spacecraft
  • Mars magnetic field analyses
  • Assisted hardware and field testing of Sino-Magnetic Array at Low Latitudes(SMALL) ground-based magnetometers
