Matej Pavsic

Matej Pavšic is a physicist interested in foundations of theoretical physics. During his more than 40 years of research at the Jozef Stefan Institute in Ljubljana, Slovenia, he often investigated the subjects that were not currently of wide interest, but later became hot topics. For example, in the 70s he studied higher dimensional, Kaluza-Klein theories, and in the 80s he proposed an early version of the braneworld scenario that was published, among others, in Classical and Quantum Gravity. Altogether, Pavsic has published more than one hundred scientific papers and the book The Landscape of Theoretical Physics: A Global View. He is among the pioneering authors in topics such as mirror particles, braneworld, and Clifford space, and has recently published important works explaining why negative energies in higher derivative theories are not problematic, which is crucial for quantum gravity. Pavsic studied physics at the University of Ljubljana. After obtaining his master's degree in 1975, he spent a year at the Institute of Theoretical Physics in Catania, Italy, where he collaborated with Erasmo Recami and Piero Caldirola. Under their supervision he completed his PhD thesis which he later defended at the University of Ljubljana. Pavsic has participated at many conferences as an invited speaker and regularly visited the International Centre for Theoretical Physics (ICTP) in Trieste.
