M.D., PhD. Foundation Professor of Neurosurgery at the University of Otago, New Zealand. Professor De Ridder is founder and director of the BRAI2N (Brain Research Consortium for Advanced, Innovative & Interdisciplinary Neuromodulation). His main interest is the understanding and treatment of phantom perceptions (sound, pain), especially by use of functional imaging navigated, non-invasive (TMS, tDCS, tACS, tRNS, LORETA neurofeedback) and invasive (implants) neuromodulation techniques. Dr De Ridder has developed “burst” and “noise” stimulation as novel stimulation designs for implants, and is working on other stimulation designs. Professor Dirk De Ridder has published 30 book chapters, co-edited the Textbook of Tinnitus, and has authored or co-authored more than 130 pubmed listed papers, of which 100 deal with phantom sound perception. He is reviewer for 55 journals.
