    Dr. Pulkkinen is currently Acting Director of the Heliophysics Science Division at NASA Goddard Space Flight Center. Dr. Pulkkinen received his Ph.D. in theoretical physics from the University of Helsinki, Finland in 2003. Subsequently he joined the nonlinear dynamics group at NASA Goddard Space Flight Center to carry out his postdoctoral research 2004-2006. Dr. Pulkkinen's Ph.D. and postdoctoral research involved studies on both ground effects of space weather and complex nonlinear dynamics of the magnetosphere-ionosphere system. 2011-2013 Dr. Pulkkinen worked as an Associate Director of Institute for Astrophysics and Computational Sciences and as an Associate Professor at The Catholic University of America (CUA). At CUA Dr. Pulkkinen launched a new Space Sciences and Space Weather program crafted to educate the next generation space weather scientists and operators. Dr Pulkkinen entered NASA civil service 2013 to lead Space Weather Research Center that provided heliophysics science and space weather services to NASA's robotic mission. 2017-2020 Dr Pulkkinen was the Deputy Director for the NASA GSFC Heliophysics Science Division.


    Dr. Pulkkinen has been leading numerous space weather-related projects where scientists have worked in close collaboration with the end-users. In many of these projects his work has involved empirical and first-principles modeling of space weather, analysis of data from NASA heliophysics missions and investigations of solar effects on man-made systems in space and on the ground. Dr. Pulkkinen was awarded NASA Exceptional Achievement Award 2015 and The International Kristian Birkeland Medal 2016 for his efforts to address space weather effects on power grids.

    Brief Bio

    Dr. Pulkkinen is currently Acting Director of the Heliophysics Science Division at NASA Goddard Space Flight Center. Dr. Pulkkinen received his Ph.D. in theoretical physics from the University of Helsinki, Finland in 2003. Subsequently he joined the nonlinear dynamics group at NASA Goddard Space Flight Center to carry out his postdoctoral research 2004-2006. Dr. Pulkkinen's Ph.D. and postdoctoral research involved studies on both ground effects of space weather and complex nonlinear dynamics of the magnetosphere-ionosphere system. 2011-2013 Dr. Pulkkinen worked as an Associate Director of Institute for Astrophysics and Computational Sciences and as an Associate Professor at The Catholic University of America (CUA). At CUA Dr. Pulkkinen launched a new Space Sciences and Space Weather program crafted to educate the next generation space weather scientists and operators. Dr Pulkkinen entered NASA civil service 2013 to lead Space Weather Research Center that provided heliophysics science and space weather services to NASA's robotic mission. 2017-2020 Dr Pulkkinen was the Deputy Director for the NASA GSFC Heliophysics Science Division.


    Dr. Pulkkinen has been leading numerous space weather-related projects where scientists have worked in close collaboration with the end-users. In many of these projects his work has involved empirical and first-principles modeling of space weather, analysis of data from NASA heliophysics missions and investigations of solar effects on man-made systems in space and on the ground. Dr. Pulkkinen was awarded NASA Exceptional Achievement Award 2015 and The International Kristian Birkeland Medal 2016 for his efforts to address space weather effects on power grids.
