The project will take place at the ALBA Synchrotron in Barcelona and the Instituto de Química Física “Rocasolano” in Madrid. The Alba Synchrotron (www.cells.es) is the largest Spanish scientific facility, with a lively international scientific working environment. The IQFR institute (www.iqfr.csic.es) is part of a cluster of research institutes at the CSIC campus of Serrano close to the city center. The recipient will share his/her time between both sites. Candidates should have a degree in Physics, Chemistry or a related discipline and be in a position to join a PhD program in Spain. We are looking for highly motivated individuals with an interest in materials and surface science. Experience with synchrotron studies, vacuum equipment, and programming skills are an advantage. Curiosity and motivation for groundbreaking science is assumed. The appointment will be for a maximum of four years. Interested candidates should send their CV and application letter to Dr. Juan de la Figuera (juan.delafiguera@iqfr.csic.es) and Dr. Lucía Aballe (laballe@cells.es).
