Alexa Halford is a space physics researcher at our Goddard Space Flight Center and Dartmouth College. She started researching waves in Earth’s magnetosphere as an undergraduate at Augsburg College with Mark Engebretson using ground based magnetometers in the Arctic and Antarctic. She moved away from waves to focus on geomagnetic storms and substorms during her masters at the University of Colorado Boulder with Dan Baker but returned once more to waves with her PhD at University of Newcastle NSW Australia. Her PhD thesis was on Electromagnetic Ion Cyclotron (EMIC) waves during the CRRES mission and their relationship to the plasmasphere and radiation belts.

She is member of the scientific team for a NASA-funded scientific balloon experiment project called BARREL (Balloon Array for RBSP Relativistic Electron Losses) where she looks at the population of particles lost due to these interactions. She is now currently a contractor at NASA Goddard continuing work the BARREL and NASA Van Allen Probes satellite missions.
