Nir was a Wellcome Trust-MIT Fellow during his time as a postdoc in the lab. The overall aim of his research is to create knowledge and technological innovations in the emerging field of neural prosthetics, with a prominent goal of restoring loss of visual functions. Nir received a BSc in Physics from the Israeli Institute of Technology (Technion) and MSc in Electromagnetic Engineering from the Technical University of Hamburg-Harburg (TUHH), Germany. He then moved to the Department of Medicine at Imperial College London to conduct PhD training under the supervision of Patrick Degenaar and Christopher Kennard. His PhD thesis focused on the development of Chanelrhodopsin-2 (ChR2) based retinal prosthetics. Following the completion of the PhD Nir was awarded the British BBSRC (Biotechnology and Biological Sciences Research Council) Enterprise Fellow which he conducted at the laboratory of Christofer Toumazou at the Institute of Biomedical Engineering at Imperial College London. He then moved to a tenure-track faculty position at Imperial College London.
