Ph.D., Physical Sciences, Space Research Centre of the Polish Academy of Sciences, Warsaw, Poland (2018)

B.S., Physics, University of Warsaw, Poland (2011)



Paweł Swaczyna is a space physicist studying the interaction of the heliosphere with the local interstellar medium. He received his B.Sc. and M.Sc. in Physics at the University of Warsaw, specializing in the theory of fundamental particles and interactions. His Ph.D. in Physical Sciences was granted by the Space Research Centre of the Polish Academy of Sciences in Warsaw. For his Ph.D. thesis, he developed a model of the energetic neutral atom (ENA) emission of heavy chemical elements (helium, oxygen, nitrogen, and neon) from the inner heliosheath and the IBEX ribbon under the secondary ENA mechanism. He uses observations of interstellar neutral atoms, ENAs, and pickup ions from IBEX and SWAP/New Horizons to describe the structure of the outer heliosphere and the very local interstellar medium.

Pawel worked at Princeton from May 2018 to May 2023.
