Dr. Terrin Tamati
A major focus of Terrin’s research concerns the perception of indexical (talker) variability, and how it may shed light on questions regarding the influence of prior language experience and individual perceptual and cognitive differences on speech perception. During her PhD studies at Indiana University with David Pisoni, Terrin worked on several projects examining the perception of regional and foreign accents by native and non-native listeners. She also contributed to the development of new, more realistic sentence recognition test materials in American English. This work led her to pursue her current research on how cochlear implant listeners perceive speech in more difficult, real-life environments involving speech variability. With her current work, she seeks to identify the cognitive, linguistic, and perceptual skills necessary for cochlear implant listeners to better understand speech in these real-life environments.
Dr. Christina Fuller
After her research internship that involved the next wish of cochlear implant users – now speech perception and communication are developed and most CI-users are satisfied in these fields – enjoying music, in the dB SPL group, Christina completed her MD/PhD with dB SPL in 2016. Following on Victor Hugo, ”Music expresses that which cannot be said and on which it is impossible to be silent,” the topic of her research was on music and the musical background in CI users. In her postdoctoral research, in collaboration with Dr. Rolien Free, Christina is exploring speech and music perception in a relatively understudied population of implant users, namely, early deafened late implanted individuals.
Dr. Laura Rachman
Laura is a postdoctoral researcher who joined dB SPL in 2019. Her research focuses on the effects of hearing loss and aging on voice and speech perception. During her PhD at IRCAM and the Brain and Spine Institute in Paris, she investigated the role of speaker and language familiarity in emotional voice perception, using voice transformation software. She is interested in combining behavioral and electrophysiological measures to study different processing stages involved speech perception, from low-level perception of voice cues to higher level speech understanding.
Dr. Thomas Koelewijn
Thomas joined the dB SPL group in 2019, where he investigates difficulties in voice identification, often experienced by cochlear implant users. He is interested in how low- and high-level language processing interacts during voice/speech perception and how this affects listening effort. After his PhD (2009) on cross-modal spatial attention, he worked as a researcher at the department of Ear & Hearing at the Amsterdam UMC. He worked on three projects (two financed by personal grants) that validated Pupillometry as a tool for measuring listening effort, and investigated how cognitive processes like working memory, attention, and motivation affect the pupil dilation response during effortful listening. During these projects Thomas collaborated with researchers in Boston, Linköping, Snekkersten, and Montreal and co-organized a biyearly workshop on the application of pupillometry in hearing science to assess listening effort.
Dr. Eleanor Harding
Ellie joined dB SPL in 2020 to investigate the rehabilitative effects of music on post-lingually deafened cochlear implant users, specifically in the areas of music and speech perception. In line with this, her PhD work, conducted at the Max Planck Institute CBS in Leipzig under Prof. Sonja Kotz and P.D. Dr. Daniela Sammler, spanned several topics including how musical ability is linked to music and language syntax processing. Her other research lines include: psychoneuroimmunological effects of postoperative music on patients in vulnerable populations; neurocognitive processes involved in entrainment to rhythm; the application of Neural Resonance Theory’s dynamical systems model to music and speech perception. Ellie also is affiliated with the Prins Claus Conservatory in Groningen and co-founded the conservatory-hosted Network for Interdisciplinary Research in Music (NIRM).

In addition to research staff, we closely work with our admin support. In fact they make everything happen in our lab!
I work as a staff adviser in the ENT department of the UMCG. I take care of all financial matters for the researchers. I have now been working with the research group for one year. I think it is a great enrichment to be able to meet so many people. Which also varies with time as many temporary students also join the group. What strikes me most is that everyone is so incredibly grateful for everything you do. I feel really appreciated in my place here. The fact that you have visitors every day makes it also very pleasant work. The nice thing is that people from all over the world come: Germany, England, Turkey, America, France, Egypt, Iran, China etc. Every day is different because people ask different questions. A small selection of my tasks: together planning grant proposals and budgets, taking care of budgets and reimbursements, ordering materials and equipment, paying participants, being the contact person for grant agencies, arranging appointments / contracts for new people, organizing seminars etc. I hope to remain a part of this for many years to come!

Dr. Debi Vickers (Cambridge)
My early research career was in the Department of Phonetics and Linguistics at University College London (UCL) where I conducted my PhD studies into high-frequency speech perception by hearing aid users, as well as working on a project to develop early cochlear implants. I continued working in auditory research and psychophysics in the Hearing Lab at the University of Cambridge looking at the perceptual consequences of hearing impairment and in particular the impact of cochlear dead regions. Over the past ten years I have been an academic at UCL, where I am a Reader (Associate Professor) in Speech and Hearing Sciences.
My speech and hearing science background drives my interest in optimising speech delivery with hearing devices to enhance communication and improve life quality; this is currently the underpinning goal for my research group. We are currently exploring cortical objective measures that could be used to guide cochlear implant mapping and also measures to fit hearing aids in babies. We are evaluating the parameter space for setting up individualised implant mapping and developing training approaches for optimising outcomes.
I also work closely with clinicians and researchers to change the candidacy criteria for cochlear implants in the UK and I am involved in the NHS England research and innovation group. I am a sub-theme lead on “Transforming Hearing Devices” for the UCL Biomedical Research Centre on Deafness.

Mustafa joined dB SPL in 2021 as a guest scientist for his postdoctoral studies funded by The Scientific and Technological Research Council of Turkey on online psychoacoustic test development for cochlear implant users. His doctoral studies on music perception of cochlear implant users were conducted at the Marmara University under the supervision of Prof. Dr Ayça Çiprut and he collaborated with Prof. Dr Jay T. Rubinstein at the University of Washington. He is teaching hearing science and music perception at Ankara Medipol University in Turkey.
Dr. Olivier Crouzet (University of Nantes, France)
I am a permanent lecturer in Nantes University (France). I’m interested in dynamical aspects of speech perception and production. These involve two complementary properties that I try to investigate. One is
whether fast temporal changes in speech signals, which relate to fast movements in speech production, can hold information that is meaningful for speech comprehension. This involves studying changes in acoustic speech cues on relatively short time scales that typically “join” two successive segments in the speech chain (like /b/ and /a/ in /ba/). Another side of “dynamics in speech” relates to the fact that the speech signal provides many different forms of information (about the speaker identity, gender, mood as well as about the linguistic content) that interact together. Access to one of this dimensions of information is tightly related to the other dimensions, for example changes in speaker’s voice impact the perception of vowel categories. We try to model how listeners dynamically access and combine these information simultaneously. Part of this work is conducted in Deniz Başkent’s team, targeting both normal-hearing speakers and deaf patients wearing cochlear implants.
