Matti Hämäläinen is a Professor of Radiology at Harvard Medical School and Director of the David Cohen Magnetoencephalography (MEG) Laboratory at the Department of Radiology, Massachusetts General Hospital. He is one of the pioneers in the application of MEG in conjunction with other non-invasive functional and anatomical imaging methods to study human brain function. He has had a crucial role in developing whole-head MEG instrumentation, analytical methods and tools, as well as experimental protocols, which have together paved the way for MEG becoming an important basic research and clinical tool worldwide.
