Biography:
Dr Jacek Ksawery (Jaksa) Osiński is a postdoctoral researcher in the Particle Astrophysics group at AstroCeNT.
Jaksa earned his BSc in Astrophysics, MSc in Physics, and PhD in Physics in the United States at the University of New Mexico in Albuquerque. Part of his PhD work was conducted during a US Department of Energy fellowship at Los Alamos National Laboratory in New Mexico. In addition, he has taught physics and astronomy at Central New Mexico Community College as a part-time faculty member.
Jaksa’s research has focused on nonstandard expansion histories in the period before big bang nucleosynthesis, and how these histories affect dark matter production. In particular, he is interested in searching for possible connections between current observables and the properties of the very early Universe in order to probe the conditions of the Universe at these early times. He has worked on a variety of thermal/nonthermal dark matter production mechanisms, including freeze-out/freeze-in, primordial black holes, and topological dark matter.
