Dr. Christoph Grün is a postdoctoral researcher at the Institute of Functional Interfaces (IFG) at the Karlsruhe Institute of Technology (KIT), Germany, and founder and CEO of CAVIGEN UG, a start-up developing oxygen-sensitive systems for 3D cell culture and Organ-on-Chip applications. He holds a PhD in Natural Sciences (summa cum laude) and an M.Sc. in Chemical Biology from KIT, as well as a qualification as a biological laboratory technician. His research focuses on 3D cell culture, Organ-on-Chip technologies, microfluidics, and optical oxygen sensing to create more physiologically relevant in vitro models for drug screening and toxicology. He has led several publicly funded translational projects, including an EXIST Research Transfer project in the field of Organ-on-Chip systems, and is co-inventor on multiple patents and co-author of peer-reviewed publications in this area. Dr. Grün has received recognitions for his work at the interface of life sciences and technology, including the DECHEMA Student Award and prizes in innovation and start-up competitions.
