Professor Macyk was on the TOP 2% list of the best scientists in the world. The ranking – developed by Stanford University in cooperation with the Elsevier publishing house and SciTech Strategies – evaluates the entire scientific output of individual researchers according to a bibliometric index, which takes into account criteria such as the Hirsch index, number of citations (including self-citations), Impact Factor, place and role on list of authors (first, last place).
