Katelynn Greer is currently working as an Assistant Research Physicist at the Space Sciences Laboratory at the University of California- Berkeley, working with Tom Immel and Scott England. She studied at the University of Colorado at Boulder in the department of Aerospace Engineering Sciences where she earned her BS (2007) and MS (2009). She completed her PhD research & dissertation in December 2013.

Katelynn is currently part of a research group directed by Dr. Tom Immel that focuses on ionospheric structures and dynamics influenced by both space weather coming in from above and terrestrial weather from below. Work by Immel and Mannucci [2013] has indicated that geomagnetic storms cause a larger effect on the ionospheric TEC (Total Electron Count) in the American sector than anywhere else on the planet, suggesting that there is a longitude dependent (UT) effect which is important for correctly understanding the impact, structure and timing of geomagnetic storms. Katelynn is working to examine the extent to which numerical models appropriately reproduce the observed results, using a model to examine the underlying mechanisms of the longitude-dependent storm enhancements and whether these mid-latitude enhancements are connected to high-latitude changes. Astrid Maute has sponsored her work on a project involving machine learning techniques to identify structures in ionospheric plasma as observed by the LISN network in South America and investigate application to model results of Sudden Stratospheric Warming periods. More about her science interests are described at katelynngreer.com.

She is also supporting the upcoming NASA mission ICON, which is to be launched in June 2017. In addition to anticipating exciting new ionospheric science that will be made possible with ICON, she is applying her aerospace engineering background to assist in developing the Science Data Pipeline which will make the observations collected by ICON easily available to other scientists for their own investigations.

Katelynn is always up for a back-country adventure, or anything outside: hiking, skiing, exploring. She can be found playing ice hockey several times a week or just enjoying Planet Boulder while she's here!
