Risto Ilmoniemi
Professor emeritus Risto Ilmoniemi is a physicist and neuroscientist working at Aalto University. He has built and designed multichannel MEG instruments and co-invented for MEG use the minimum-norm estimate, invented the signal-space projection and other mathematical methods for the forward and inverse problem, the channel-capacity measure for comparing sensor arrays, and the triangle phantom. With his co-workers, he has developed several transcranial magnetic stimulation (TMS) techniques such as navigated TMS (nTMS), the combined use of TMS and EEG, and multi-locus TMS.
