Tilmann Sander has a Diplom and PhD in Physics from ETH Zürich and Imperial College London, respectively. In 1998 he joined the field of biomedical engineering in a cooperation between Charité and Physikalisch-Technische Bundesanstalt (PTB) researching MEG. Since 2000 he has been a staff member at PTB and developed software and hardware for SQUID-MEG and later for MEG using optically pumped magnetometers (OPM). His current projects involve engineering for multi-modal imaging devices combining fNIRS or EEG with OPM-MEG. He has published numerous papers in the field and contributed to a range of books and conferences.​​​​​​​
