The Group Members

Head of the Group

Prof. Dr. Dr. Livia Ludhova Focus of Research: Livia Ludhova is specialized in low-energy neutrino physics with large-volume liquid-scintillator detectors. She is a member of the Borexino collaboration since 2005 and currently serves in a role of its physics co-coordinator. She joined the JUNO collaboration in 2014 and is a member of its recently established Analysis Coordination Committee. Livia Ludhova has a long-term experience with the measurement of solar neutrinos and geoneutrinos.
