Characterizing the effects of traumatic brain injury on individuals who live on Vancouver's Downtown Eastside
My doctoral work is part of the prospective longitudinal 'Hotel Study' which follows Vancouver Downtown Eastside residents who live in single room occupancy hotel rooms. We aim to retrospectively assess lifetime traumatic brain injury as a risk factor for marginal housing and psychiatric illness, and prospectively evaluate the effect of incident traumatic brain injury on neuropsychiatric and functional trajectories.
Evaluating the diagnostic utility of smooth pursuit eye movements in mild traumatic brain injury
In my undergraduate I led a pilot clinical study assessing the performance of using smooth pursuit eye movement as a diagnostic indicator of mild traumatic brain injury (Stubbs et al. 2019. Scientific Reports). We're now employing the same paradigm in collaboration with UBC Varsity Athletics to longitudinally assess eye movements in Varsity athletes post-concussion.
Isolating the type of somatic symptoms experienced by individuals with post-concussion syndrome
In collaboration with the Canadian Traumatic Brain Injury Research Consortium we conducted a small study on the type of somatic symptoms reported by individuals with post-concussion syndrome (submitted).
Examining how working memory and attention interact with smooth pursuit eye movement
We showed that smooth pursuit eye movement variability improves with higher amounts of working memory load in health individuals (Stubbs et al. 2018. Experimental Brain Research). This study laid the foundation for our upcoming publication detailing how this eye movement paradigm is more sensitive and specific than general smooth pursuit eye movement for diagnosing mild traumatic brain injury.
Characterizing a novel association between prosopagnosia ('face blindness') and amusia ('tone deafness')
Following anecdotal reports from our prosopagnosic participants and amusic participants tested by our collaborators at Harvard Medical School, we formally tested musicality in participants with developmental prosopagnosia (Corrow et al. 2019. Neuropsychologia). We then tested musicality in participants with acquired prosopagnosia, yielding a strikingly similar finding (in review). This work fundamentally shifts our understanding of prosopagnosia from purely a visual disorder to a more broad developmental or connective disorder encompassing multiple perceptual systems.
