There is a vacancy for a postdoc position, with a contract of 1 year and 4 months, to work in the context of the ESC2RAD H2020 project “Enabling Smart Computations to study space RADiation effects” http://www.esc2rad.eu/. The postdoc will work on the modeling of space radiation effects (mainly protons and electrons) on different components of future human Space missions, such as functional materials of the spacecraft and biological molecules of relevance for DNA damage in astronauts. The postdoc will work with first-principles chemical physics approaches for the passage of particles through matter, such as time-dependent DFT (TDDFT), and, for the studies on functional materials, also with Monte Carlo particle transport approaches, as implemented in Geant4.
