Rodney Michael John Cotterill Order of the Dannebrog (27 September 1933 – 24 June 2007) was an English-Danish physicist, and neuroscientist, who was educated at University College London (B.Sc., 1st), Yale (M.S.) and Cambridge University (Ph.D.). He spent most of his career as a professor at the Technical University of Denmark, Denmark, (1967-) after having spent five years as a researcher at the Argonne National Laboratory.
Cotterill was a prolific scientist who published over two hundred highly cited papers and books on a variety of topics in physics, biology and medicine. His initial research was in materials science, which was of such a high standard that he was subsequently elected to the Royal Danish Academy of Sciences and Letters. He became gradually more interested in biophysics, and especially the human brain, where he subsequently made important contributions to the study of consciousness.
He was awarded Knight, first class of the Dannebrog in 1994 and given an honorary D.Sc. in 1973 by London University in materials science. Cotterill was a Fellow of the Institute of Physics (U.K.) (1967), Fellow, Danish Academy of Technical Science (1974-, Presidium, 1985-7) and a Fellow of the Royal Danish Academy of Sciences and Letters (1984-, Presidium 1990-6). He was awarded the Hans and Ellen Hermer Memorial Prize in 1978 for his pioneering work in computer simulation.
