Heidi Nykyri
Dr. Nykyri obtained her masters degree in theoretical physics in University of Helsinki, Finland in 1998 after which she continued to do a Ph.D in Physics in University of Alaska Fairbanks as well as another M.S degree in Computational Physics. In her Ph.D thesis she demonstrated for the first time how Kelvin-Helmholtz Instability can produce significant plasma transport due to magnetic reconnection. She obtained her doctorate in Physics in 2002 after which she worked as post doctoral research associate in Imperial College, London between 2002-2007. She is a co-investigator for the Flux Gate Magnetometer onboard 4 Cluster spacecraft and received in 2005 and 2015 European Space Agency award for Cluster Exploration of Geospace. In January 2007 she started as a assistant professor of Physics in Embry-Riddle and was tenured and promoted to associate professor in 2010, and to a full professor of physics in 2016. Dr. Nykyri has an externally funded research program in magnetospheric physics and supervises ERAU undergraduate, graduate and Ph.D student research. Her major research interests involve understanding the physical mechanisms that transport and heat plasma in solar wind -magnetosphere system. Dr. Nykyri was awarded the NSF career award in 2009 and ERAU researcher of the year award in 2010 and 2018.  She is a Co-director of the ERAU's LASMIR laboratory.  Between 2012-2018 she served as a Steering committee member of the National Science Foundation's GEM program as a research area coordinator for the Solar Wind Magnetosphere Interactions research area. Since Fall 2017 Dr. Nykyri is the Associate Director for Embry-Riddle's Centre of Space and Atmospheric Research (CSAR)  http://csar.erau.edu/ and Director for Space Weather Division. Nykyri also acted in academic service role, as an associate dean for research between 2018-2021. Since 2021 she serves as a Vice Chair for Magnetospheric Division for the Committee of Space Research, COSPAR.
