Gunnar Schmidtmann

Gunnar studied Medicine and Optometry at University of Lübeck in Germany. He obtained his Ph.D. from Glasgow Caledonian University, Scotland in 2013, where he studied aspects of shape perception in Gunter Loffler’s lab. From 2013-2016, he worked as a postdoctoral research fellow in Fred Kingdom’s lab at the McGill Vision Research group studying intermediate-level visual processing, contour-shape and curvature encoding and signal detection theory. Gunnar has recently joined the Farivar lab to investigate visual functions of patients with traumatic brain injuries (TBI). It is envisaged to conduct psychophysical and neuroimaging (fMRI) experiments to understand the mechanisms underlying frequently described visual discomfort after TBI and to develop recovery tools for such patients.


Graduate Students

Yiran Chen

Yiran is working on a project studying the reliable pattern of cortical activity during naturalistic viewing. Using MEG, we are able to investigate cortical activities patterns in different frequency bands. We adopt inter-subject synchronization as a measurement of reliable pattern. This synchronization can include both time-course correlation and spatial-spectral pattern similarity. In addition to basic anatomical alignment of cortical surface, I am also interested in functional hyper-alignment. We want to test our methods on identifying binocular disparity related cortical patterns using out movie-viewing data.

Angela Zhang

Angela received her B.Sc in Neuroscience at Western University and is now pursuing her Masters in Neuroscience.  Her research interests include mild Traumatic Brain Injury (mTBI) and visual perception in humans and monkeys.  Her projects use fMRI and psychophysical tasks to explore visual recovery following mTBI in a monkey model and to examine visual perception in humans.

Hassan Akhavein

Hassan studied physics as an undergraduate student at Sharif University of Tech, Iran. He received a M.Sc. in Physics at Concordia University, Montreal. He currently pursuing his Ph.D. in Neuroscience at McGill University. His interest includes saccadic eye-movement, depth perception and object recognition.

Tatiana Ruiz

Tatiana graduated with a B.Sc. in Psychology from Université de Montréal in 2015. As a graduate student at McGill in the Integrated Program in Neuroscience, she is investigating the visual dysfunctions experienced by patients who suffer from mild traumatic brain injury (mTBI). More specifically, her research focuses on low- and mid-level processing of visual information (contrast sensitivity, disparity sensitivity, and contour integration) in mTBI, using psychophysics and transcranial magnetic stimulation. She is also interested in neuroimaging and neuro-endocrinology.

Sébastien Proulx

Bachelor’s in Health Sciences and Master in Neuroscience at Université de Montréal, Sébastien is interested in finding new ways to investigate function and plasticity of the human brain, focusing on the more easily accessible motor and visual systems. His current projects more specifically aim at measuring and modulating neural inhibition in the visual system of the human brain, using psychophysics, transcranial magnetic stimulation (TMS), functional magnetic resonance imaging (fMRI), magnetic resonance spectroscopy (MRS) and monocular deprivation.

Charlene Yang

Charlene obtained a Bachelor degree in Psychology at McGill University in 2016. She is currently pursuing her master as an IPN (Integrated Program in Neuroscience) student in McGill. Her current project aims at restoring binocular vision in amblyopia by through engagement of stimulus-specific adaptive compensatory mechanisms. 

William Mathieu

William obtained a bachelor's degree in electrical engineering (B.Eng.) at McGill University in Montreal and will begin a Master’s in the same field in the fall. His research interests include medical imaging hardware, electromagnetics, radio-frequency microelectronics, and signal processing. He is currently working on the design and development of MR hardware, specifically radio-frequency receive coils for concurrent MRI and transcranial magnetic stimulation experiments.

Research Assitants

Dasha Sandra

Dasha is currently pursuing her undergraduate studies as an Honours Psychology student at McGill University. She is interested in the neuroscience of perception and thought processes. She is particularly interested in the effects of cognitive demand on perception and decision making, visual perception of TBI patients, as well as the theory of mind.
