Agnieszka Zalewska is a Polish physicist, specializing in experimental particle physics. She graduated and obtained her PhD at the Jagellonian University in Cracow. Currently she is a professor and head of the Department of Neutrino and Dark Matter Physics at the Henryk Niewodniczanski Institute of Nuclear Physics of the Polish Academy of Sciences in Cracow. She has also worked, altogether for more than seven years,  in other particle physics laboratories, including CERN, Geneva, Switzerland; University of Washington, Seattle, USA; CEA, Saclay, France; Pavia and Gran Sasso, Italy; JPARC, Japan.

Scientific research of A. Zalewska has been characterised by a wide spectrum of physics subjects and applied methods. In particular, it includes hadron physics, e+e- interactions, neutrino and dark matter physics as well as pioneering work on silicon vertex and tracking detectors with VLSI electronics at CERN. She has been responsible for several projects in particle physics in Poland and has been leader of Polish groups in large international collaborations and in European projects. She also served in numerous scientific committees, in particular in the Scientific Policy Committee at CERN. Since January 2013 she has been the President of CERN Council.
