Olga Botner is a Professor at the Department of Physics and Astronomy, specifically in the High Energy Physics division, at Uppsala University. Her research focuses on astroparticle physics, with particular emphasis on the exploration of the Universe through cosmic neutrinos, which are considered ideal astrophysical messengers due to their ability to travel unaffected by magnetic fields and unhindered by matter and radiation. She is an active member of the IceCube Collaboration, which operates the world's largest neutrino telescope, the IceCube Observatory located at the South Pole. Professor Botner's research interests center around astroparticle physics, particularly the exploration of the Universe with cosmic neutrinos that may have been created in the environments of black holes. Her work is crucial for multi-messenger astronomy, which combines observations of different cosmic messengers like photons, cosmic rays, gravitational waves, and neutrinos to gain a comprehensive understanding of astrophysical phenomena. Her research spans neutrino astronomy, dark matter detection, cosmic ray physics, and the development of advanced analysis techniques including machine learning applications in neutrino data analysis. The recent publications by Professor Botner demonstrate a strong focus on neutrino physics and astroparticle research. Her work spans multiple areas including neutrino oscillation studies, dark matter searches, cosmic ray anisotropy, multi-messenger astronomy, and the development of advanced instrumentation like the Radio Neutrino Observatory in Greenland (RNO-G). A significant portion of her recent work involves the application of machine learning techniques to neutrino data analysis, particularly convolutional neural networks for atmospheric neutrino oscillation parameter measurements. Her research also explores fundamental physics questions related to sterile neutrinos and potential beyond Standard Model physics. As a key member of the IceCube Collaboration, Professor Botner contributes to one of the most significant neutrino observatories in the world, located at the South Pole. This international collaboration involves researchers from numerous institutions worldwide working together to detect and study high-energy neutrinos from cosmic sources. Her work connects fundamental particle physics with astrophysical observations, bridging the gap between these two fields to address some of the most profound questions about our Universe.
