Heli Hietala studies particle energization in shocks, magnetic reconnection, and radiation belts using multi-spacecraft observations and modelling.
She is the lead-proposer and co-chair of the GEM Focus Group Dayside kinetic processes in global solar wind - magnetosphere interaction (2016-2020).
She's also the co-leader of the International Space Science Institute (ISSI) International Team Jets Downstream of Collisionless Shocks (2015-2017), and the co-I of the global hybrid-Vlasov simulation model Vlasiator.
She was a Young Scientist in the ISSI team Ion and Electron Bulk Heating by Magnetic Reconnection (2013-2015).
She is currently an Assistant Researcher in the Experimental Space Physics Group, Department of Earth, Planetary, and Space Sciences, University of California, Los Angeles.
