Dr Sebastian Trojanowski is a theoretical physicist specializing in (astro)particle physics and particle cosmology. He works in AstroCeNT – Particle Astrophysics Science and Technology Center as a postdoctoral researcher in the Particle Astrophysics group. He is also employed in the Theoretical Physics division of the National Centre for Nuclear Research (NCBJ) in Poland.

He received his doctoral degree at NCBJ in 2015. In his PhD research, he was focusing on the phenomenology of supersymmetric models that are among the most important candidates for beyond the Standard Model (BSM) theories and are targeted i.a. in various ongoing dark matter and Large Hadron Collider (LHC) searches. He then joined the Theoretical Particle Physics Group at the University of California, Irvine (UCI) for his first postdoctoral post (2016-18) and, subsequently, he was hired as a Research Associate in the Cosmology and Relativity Group at the University of Sheffield, UK (2018-20) before coming back to Poland to join AstroCeNT in 2020.

Dr. Trojanowski’s research focuses on dark matter studies and related aspects of astrophysics, cosmology, and various experimental searches. In particular, he co-proposed the idea for a new direction in BSM searches at the LHC. As a result of this research, a new experimental collaboration has been formed, namely the ForwArd Search ExpeRiment (FASER), to study interactions of high-energy neutrinos and search for possible signatures of light new physics. His other studies correspond to a broad range of proposed explanations for the nature of dark matter in the Universe.

A list of his publications can be found in the service INSPIRE HEP.
