Arnau holds a BSc. and an MSc. in aeronautical engineering with specialization in space engineering by the Polytechnic University of Catalonia (UPC-BarcelonaTech), in Barcelona, Spain. Moreover, he holds a MSc. of Aerospace Propulsion Theory and Engineering by Beihang University in Beijing, China. He also attended the International Space University Space Studies Program 2015, hosted by Ohio University in partnership with NASA Glenn Research Center. He worked as a research assistant at the Hybrid Rocket Motors Laboratory at Beihang University. At this capacity, he designed, performed 3D CFD simulations and experimentally tested an innovative injector configuration towards increasing the performance of hybrid rockets. In addition, he has recently been admitted at the Ph.D. program in Aeronautics and Astronautics at Purdue University (West Lafayette, IN) starting in Fall 2016. His research interests encompass space propulsion systems as well as the development of 3D printing and in situ resource utilization technologies for enabling human space exploration into the solar system and beyond.
