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. He is founder and former CEO of Nexstim Plc. He has led the development of new technologies and methods for hybrid MEG–MRI and for TMS. He is founder and was the first Chair of the Biodesign Finland Program; he participates also in several other innovation-promotion activities. He has lectured on classical electromagnetism, functional imaging, MEG and EEG, and neuroscience.
