Biography

In 2009, Ksenia graduated Summa Cum Laude from the Faculty of Physics of the Lomonosov Moscow State University (MSU), Russia, and then started a postgraduate program at the same university. She completed her postgraduate studies in Plasma Physics in May 2012. Ksenia’s thesis was devoted to understanding acceleration and loss processes of relativistic electrons in the outer Earth’s radiation belt due to resonant interaction with chorus waves. The same year she won a prestigious Jack Eddy Postdoctoral Fellowship of the NASA’s Living with a Star program and worked as a postdoctoral researcher at the University of California, Los Angeles (UCLA), USA, for two years. Ksenia is now working in Skolkovo Institute of Science and Technology (Skoltech), Russia, as Research Scientist and is closely collaborating with UCLA.

Ksenia Orlova is an author of papers published in Nature Physics, Geophysical Research Letters, Physics of Plasmas, Journal of Geophysical Research, Space Science Reviews, Annales Geophysicae, Geomagnetism and Aeronomy, and other journals, both as a first author and in collaboration with other scientists. She has made oral and poster presentations at various international conferences such as American Geophysical Union Fall Meetings (AGU), European Geosciences Union General Assemblies (EGU), and Committee on Space Research Scientific Assemblies (COSPAR), Geospace Environment Modeling Workshops (GEM), and others.
