The choice is yours: will you become a specialist in pure or applied mathematics (such as statistics, physical applied and engineering mathematics)? Will you choose a teaching or professional track? With your problem-solving expertise, you will contribute to technological progress in fields as diverse as infrastructure, economics, education and healthcare. Erasmus Mundus Joint Master Degrees (EMJMD) are prestigious, internationally recognised graduate programmes funded by the European Union. These programmes are jointly organised by at least three different universities from at least three different European countries. The Erasmus Mundus Master of Theoretical Chemistry and Computational Modelling is a joint initiative of and organised by: Modern chemistry would be unthinkable without the achievements of theoretical and computational chemistry. These disciplines became an essential tool for the molecular sciences towards the end of the 20th century, and they will undoubtedly mark the new era that lies ahead. From this perspective, training and educating new generations of computational and theoretical chemists with a broad, practice-based knowledge is of paramount importance. Experts from several European universities have come together to do just that.
