Dr. Philipp Arnold studied biology at the Johannes-Gutenberg University (Mainz, Germany). There he obtained his diploma in 2008 and then started his PhD in structural biology in the Department of Zoology at the same university. During his PhD training, he worked on different macromolecular protein complexes using cryo-transmission electron microscopy and single particle analysis. He obtained his PhD in 2012 and, after a short postdoctoral period of six months in the same institute, he moved to Kiel and became an independent group leader in the Anatomical Institute of the University of Kiel. Besides research on proteolytic processes that regulate inflammation and fibrosis, he is the scientific coordinator of the microscopic unit in the institute, applying different light microscopic techniques as well as scanning and transmission electron microscopy.
