Zbigniew Szadkowski obtained his Ph.D. in Theoretical Physics from the University of Lodz, Poland, in 1987 with his thesis, "Quark mixing in the SU(4) x SU(4) and SU(6) x SU(6) chiral symmetries." In 2007 he obtained a DSci in Experimental Physics based on the thesis, "Triggers in the Pierre Auger Observatory." Since 1998, Dr. Szadkowski has been working in the Pierre Auger Observatory designing the second-level trigger imple-

mented in all 24 fluorescence telescopes, the first-level trigger implemented in all 1660 surface detectors, the Front End Boards with 800 ACEX and 900 Cyclone field-programmable gate arrays (FPGAs), and many trigger algorithms based on discrete cosine transform, artificial neural networks, or fuzzy logic. He worked at the Michigan Technological University, USA, the College de France, Paris, and the Bergische Universität Wuppertal, Germany.
