Anthony T. Cacace, PhD, is an audiologist and research professor of Communication Sciences and Disorders at Wayne State University. He was staff scientist at the Advanced Imaging Center, the Neurosciences Institute, Department of Neurology, and was Director of Oto-Neurological Research in the Division of Otolaryngology at Albany Medical College before transitioning to Wayne State University. His interests include auditory processing disorders, psychoacoustics, electroacoustics (otoacoustic emissions, middle ear power reflectance), electrophysiology, neuroimaging, and tinnitus.Emile de Kleine, PhD, is a medical physicist-audiologist at the University Medical Center Groningen, The Netherlands. He earned his degree in Applied Physics at University of Twente, The Netherlands. After that he subsequently did his PhD and his training in audiology at the Department of Otorhinolaryngology at the University Medical Center Groningen. His interests include otoacoustic emissions, cochlear implantation, tinnitus, and hyperacusis.Avril Genene Holt, PhD, is an auditory neuroscientist and Associate Professor within the Department of Anatomy and Cell Biology at Wayne State University School of Medicine. Her research focuses on auditory system function, specifically on ways of modulating hearing and tinnitus. Current work is associated with rhodopsin (CHR2 and HALO), dopamine, calcium-channel blockers, vGlut (1-3), and 2--port domain potassium channels. Of particular interest is the application of calcium channel blockers and the combined use of pre-pulse inhibition of startle reflex and manganese enhanced magnetic resonance imaging (MEMRI) for identifying biomarkers in animal models of noise-induced tinnitus.Pim van Dijk, PhD, is a medical physicist -- audiologist at the University Medical Center Groningen and a professor of audiology at the University of Groningen, The Netherlands. His interests include the biophysics of hearing, clinical audiology, and the neuroscience of tinnitus. His recent work includes otoacoustic emission research in various vertebrate species and neuroimaging studies in tinnitus patients.
