Dennis Bonatsos received his B.Sc. degree in Physics from the University of Patras, Greece, in 1979, and his Ph.D. degree in Theoretical Nuclear Physics from the University of Pennsylvania, USA, in 1985. He is currently a Director of Research in the Institute of Nuclear and Particle Physics of the National Centre for Scientific Research (NCSR) Demokritos in Athens, Greece. He has held positions in the universities of Oxford (UK), Tuebigen (Germany), Fribourg (Switzerland), as well as in the European Centre for Theoretical Studies in Nuclear Physics and Related Areas (ECT*) in Trento (Italy). He has served on the Board of the Nuclear Physics Division of the European Physical Society (EPS), the committee of the Lise Meitner Prize in Nuclear Physics of the EPS, and the Board of Directors of NCSR Demokritos for many years. He has supervised 15 Ph.D. theses and has taught, for many years, postgraduate courses in the School of Applied Mathematical and Physical Sciences of the National Technical University of Athens. He has worked on algebraic models (including quantum groups) for nuclei, molecules, and atomic clusters, as well as on shape/phase transitions, and critical point symmetries (CPS) in atomic nuclei. In 2004-2006
he proposed the Z(5), Z(4), and X(3) CPS. In 2017 he proposed the proxy-SU(3) symmetry in atomic nuclei. He authored a book on algebraic models of nuclear structure (Clarendon, Oxford, 1988) and a postgraduate textbook on Advanced Quantum Mechanics (in Greek).
