Doctoral Researcher, Space Physics and Astronomy - Oulun yliopisto - Oulu, Finland

We are now looking for Doctoral Researcher to join us in the Space Physics and Astronomy Research Unit at the Faculty of Science. The position is fixed term for 4 years. In the Ionospheric Physics research group we study the effects of solar storms and space weather on the ionosphere-thermosphere system. We utilize a comprehensive set of measurements from ground-based instruments and satellites in our research, supported by advanced numerical simulations. The research group consists of one professor, three senior researchers, four postdoctoral researchers and about eight doctoral researchers, and has a wide national and international network of collaborators. As a doctoral researcher you will be a member of the newly established Finnish Centre of Excellence in Space Resilience, where your task is to study global changes in the ionosphere-thermosphere system induced by geomagnetic storms. Building on previous work conducted in our research group, you will be using global data-driven modelling based on SuperDARN, SuperMAG and AMPERE data to estimate ionospheric Joule heating and compare it with thermospheric neutral mass density variations measured by satellites (e.g., Swarm, GRACE, GOCE) in order to investigate the changes in atmospheric drag experienced by satellites at low-Earth orbits (LEO). In addition, you will apply those results in development of physics-informed machine learning methods. What we offer? The support of an experienced and enthusiastic team of about twenty people at University of Oulu and the large nation-wide Space Resilience Center of Excellence community distributed to University of Helsinki, Aalto University, Finnish Meteorological Institute and University of Turku, where you can share your expertise and grow as an expert.
