CURRICULUM VITAE
Google Scholar Page

Dr. Johnsrude received her BSc in Psychology from Queen’s University in Kingston, Ontario. She then trained at the Montreal Neurological Institute and McGill University with pioneering neuropsychologist Brenda Milner, receiving her PhD in clinical psychology in 1997. After a postdoctoral fellowship at the Wellcome Trust Centre for Neuroimaging in London UK, the home of Statistical Parametric Mapping (SPM), she was recruited to the Medical Research Council Cognition and Brain Sciences Unit, Cambridge, UK to help start a neuroimaging program there. In Cambridge, she worked with, and learned from, many wonderful auditory and cognitive scientists. After four years there, she returned to her alma mater, Queen's University, where she held a prestigious Canada Research Chair for 10 years. She was recruited to Western University in 2014, as the first Western Research Chair. Dr Johnsrude’s work has been recognized by awards and honours including NSERC’s EWR Steacie Award, and she is particularly proud of her IgNobel Prize, with Eleanor Maguire and others, for ‘the London taxi-driver study’. Dr Johnsrude has published over 100 papers and articles, which together have been cited over 16,200 times. Postdoctoral and graduate trainees have gone onto professional careers in audiology and clinical psychology, to industrial research careers at international and Canadian companies, and to academic positions in Canada, the US, the UK and Europe. More than half of Dr Johnsrude’s undergraduate trainees have gone on to professional training (audiology, business, law, medicine, speech pathology) or to graduate school.

The range of sounds we experience varies greatly when we transition from, for example, a quiet mid-afternoon hike on an abandoned mountain to a loud rock concert in a group of thousands of fans. One scientific question of substantial importance to understanding human experience is how exactly our brains are capable of adjusting to contexts in which the sound experience varies so greatly. It is hard to imagine how our brains could cope with such extreme differences between soundscapes without substantial flexibility in the way they respond. My research makes use of electroencephalography, magnetoencephalography, and functional imaging in order to investigate the flexibility with which neural activity and human perception adjusts to the acoustic properties of the environment, and whether flexibility in neural and perceptual adjustments change when growing older. I strongly focus on auditory sensory processes and investigate stimulus-evoked activity as well as neural oscillations as prime candidates for expressing flexible adjustments to, for example, spectral and temporal properties of the environment.

 Andrew Dykstra, PhD.
Postdoctoral Fellow, Room: WIRB 4115

How sensory stimuli transcend subconscious processing and enter awareness is a fundamental question of neuroscience. To date, most of our knowledge concerning this topic comes from vision, and there is comparatively little known about conscious perception in other modalities. My research uses multimodal neuroimaging (M/EEG, fMRI, intracranial EEG) combined with novel behavioral paradigms and advanced analysis methods to examine the neural basis of conscious auditory perception and other related aspects of auditory cognition (selective attention, decision making, working memory). I am particularly interested in how conscious perception emerges - and of which elements or groups of elements - in complex auditory scenes (for example, a busy street corner or a crowded bar), and how this might change with age, hearing loss, or brain injury. Such knowledge has the potential to inform the design of better auditory prosthetics and diagnostics for those suffering from hearing loss or disorders of consciousness. 
   
 
 
Vanessa Irsik, PhD.
Postdoctoral Fellow, Room: WIRB 4115

Sounds are ubiquitous in most natural settings and are a fundamental part of basic perceptual experience. Yet, sound perception in real-world situations can be particularly challenging due to inherent processing constraints of the auditory system and the overall complexity of most listening environments. Thus far, my research has focused on using a combination of behavioral and physiological measures (i.e., EEG) to better understand how we perceptually organize complex auditory scenes, and the limitations of our scene analysis processes via investigating the phenomenon of change deafness. Currently, I am interested in identifying the neural substrates of the auditory processing deficits that occur as we age. In particular, I am interested in examining how processing in cortical and subcortical structures contribute to the temporal processing deficits observed in older adults.

 
   
 
 
Stephen Van Hedger, PhD.
Postdoctoral Fellow, Room: WIRB 4115

My research focuses on fundamental questions in the domain of learning and memory on the one hand, and in the domain of pattern understanding on the other. The way in which I integrate these two areas of research is through the study of perceptual expertise – specifically, how it develops and is how it is maintained by the environment. Much of my research has focused on music and speech as a model systems, in part because there is such variability in these domains. In music, using a combination of behavioral and fMRI paradigms, my current focus is on how individual and environmental factors contribute to the learning and memory of absolute pitch categories. In speech, using a combination of behavioral, fMRI, and EEG paradigms, my current focus is on the development of talker-specific representations, with a particular emphasis on how perceptual expertise with a given talker can improve speech understanding in challenging listening environments.

Mason Kadem
MSc. Student, Room: WIRB 4115

My undergraduate thesis was the first attempt at acquiring pupil measures through an online interface (Mturk). Currently, I am a MSc Neuroscience student under the supervision of Dr. Johnsrude. I use functional magnetic resonance imaging and pupillometry to assess cognitive load in challenging listening environments. In addition, I am interested in assessing the auditory system during spaceflight, which would indicate whether the auditory system functions normally under microgravity. This knowledge could be used to improve the safety and efficacy of space habitats

Matthew Bain
MSc. Student, Room: WIRB 4115
mbain25@uwo.ca

I completed my BSc. in Life Sciences at McMaster University, with an honours specialization in Psychology, Neuroscience, and Behaviour (PNB). I am interested, broadly, in the neural correlates of perception and cognition, and I aim to address questions related to consciousness, dementia, the auditory system, etc. I am currently working towards a MSc. in the Neuroscience program at Western, supervised by Dr. Johnsrude. The focus of my current research is to measure the cognitive resources that a listener must use to understand speech, a concept referred to as listening effort. Our approach to this problem is twofold: we will first use a reaction-time paradigm to obtain a behavioural index of listening effort and then measure neural correlates of listening effort using fMRI/EEG and an inter-subject correlation analysis.
