Dr. Arash Rahimi-Iman is a lecturer and young group leader at the Philipps-Universität Marburg, Germany, where he completed his habilitation in experimental physics. He received his Ph.D. from the Faculty of Physics at the University of Würzburg, Germany, in 2013, where he worked on the development and demonstration of an electrically pumped polariton laser. Currently, he is the principal investigator of several projects in the fields of semiconductor lasers, two-dimensional materials and polariton physics at the Department of Physics and the Materials Sciences Center in Marburg, and as part of a Sino–German Cooperation Group on Functional Nano-Materials Sciences, initiated and co-directed by him, involving research groups from several universities in China and Germany. The focus of his work is on optical spectroscopy of nanostructured systems consisting of quantum wells, quantum dots, or novel semiconductor materials, and on the development and study of semiconductor lasers.During the last decade, he has authored and co-authored over 100 publications in numerous peer-reviewed science journals, and frequently presented at international conferences. In addition, he has acted as visiting lecturer and symposium co-organiser at the Zhejiang University, China. Furthermore, Dr. Rahimi-Iman supports the academic endeavours in Marburg as a member of the Steering Committee of the Materials Science Center, as well as of the Steering Committee of the Marburg Research Academy, and as a Faculty Board member of the Physics Department in Marburg.
