Professor Jos Arrillaga, Electrical and Computer Engineering Building, University of Canterbury, Christchurch, New Zealand
Professor Arrillaga has been a professor at the University of Canterbury since 1975. He led the Power Systems group at the Manchester Institute of Science and Technology (UMIST) between 1970 and 1974. In 1997 he achieved the IEEE Uno Lamm Medal in Berlin for pioneering work in the field of High Voltage Direct Current, also the John Munganest International Power Quality Award of the Power Industry in the US. Between 1998 and 2006 he won numerous awards for his work in Paris and New Zealand, including the J.R. Scott medal of the Royal Society of New Zealand for services to Electrical Engineering education and research. So far he has published 8 books with Wiley and over 200 papers on the subjects of HVDC Transmission and Power System Harmonics.
