Christiane Rohr, PhD

Postdoctoral Fellow

I did my PhD at the Max Planck Institute for Human Cognitive and Brain Sciences, Germany, exploring the functional brain basis of emotional traits and executive capabilities in adults. I currently investigate how these traits and capabilities develop in the brains of typically developing young children, as well as in the brains of children who were born very preterm. As very preterm children face a markedly increased risk of having executive and emotional difficulties, my aim is to provide critical pieces of evidence that, in the long run, can inform the design of targeted intervention programs.


Svenja Espenhahn, PhD

Postdoctoral Fellow

I did my PhD in Clinical Neuroscience at the UCL Institute of Neurology, UK, exploring the relationship between cortical oscillations and motor skill learning in healthy adults and stroke patients. I currently use electroencephalography (EEG) and vibrotactile psychophysics to investigate typical and atypical development of somatosensory function in young children (age 3-6 years). A better understanding of the early development of tactile processing in typical children and tactile sensory abnormalities experienced by children with ASD is crucial for targeting and optimizing future sensory therapies.


Dennis Dimond, BSc

PhD Candidate - Neuroscience

I completed my BSc honors degree in neuroscience at the University of Alberta in 2015. My undergraduate thesis investigated the relationship between the brains structural networks and executive dysfunction within amyotrophic lateral sclerosis, through use of DTI data acquired at the Peter S. Allen MR Research Center in Edmonton. Here in the Bray Neuroimaging Lab I am investigating the structural and functional connectivity of attention and visuospatial memory networks in Turner syndrome. I hope that my research will help to characterize the underlying neuronal constructs of attention and memory, and shed light on how atypical neurodevelopment leads to related cognitive deficits.


Kate Godfrey, BSc

MSc Candidate - Neuroscience

I completed my BSc Neuroscience degree at the University of Lethbridge in 2017, where my undergraduate research work was focused on motivation and reward. In the Bray Neuroimaging Lab I am interested in look at the relationship between circumscribed interests and reward behavior, neurological processing, and executive functioning abilities in young children with and without autism spectrum disorder (ASD). I am hoping my research will facilitate a better understanding of the neurological correlates of circumscribed interests in autism spectrum disorder, which could have possible utility in designing therapies for targeting other symptoms which are present in this disorder.


Kirk Graff, BSc & BEd

MSc Candidate - Neuroscience

I'm back at the University of Calgary after previously completing a BSc and a BEd here. I work with functional MRI to study how the brain changes in typically developing young children (ages 4-6). I’m interested in what connections within the brain are most similar from person to person, and what connections are most unique to each individual. My goal is to better understand cognition and what allows us to establish and maintain our individual identities. My other research focus is on comparing methodologies in functional MRI with children. There’s a lot of variability in how researchers process data, and most procedures have been established with adults. I hope to increase the knowledge of the pros and cons of different approaches when working with data collected from children.


Ryann Tansey, BSc

MSc Candidate - Neuroscience

I graduated with a B.Sc. in Combined Biology & Psychology from the University of Victoria in 2017. I’m very interested in how differences of cognitive abilities in both typically developing individuals and clinical neuropsychiatric populations are reflected in brain structure and function. My research in the Bray Lab uses fMRI to investigate how the between-subject similarity of attention network activity in young, typically developing children relates to attention ability. With this research, I hope to achieve a greater understanding of how specific differences of attention skills between children are represented in brain functioning.


Shefali Rai, BASc

MSc Candidate - Neuroscience

I completed my BASc Honours degree in Chemical Engineering at the University of Waterloo in 2013. In the Bray lab, I am working with functional MRI to gain insight on unique brain network features. Most of the work in this field has been done in adult populations and through my research I hope to gain a better understanding of how individual brain networks are distinct in typically developing children.


Logan Haynes

BHSc (Honours) Candidate

My honours thesis seeks to characterize the lasting effects of preterm births on childhood brain structure.  I am analyzing structural MRI scans collected from a large cohort of 9 and 10 year-olds, which includes children born at full term and at varying degrees of prematurity.  My prior projects in the Bray lab include using EEG to understand reward learning in young children and comparing the performance of paediatric MRI processing pipelines.    


Tingting Yan

BHSc (Honors) Candidate

I’m currently working on the DELTA (development of learning and tactile function in autism in early childhood) study. My undergraduate thesis uses EEG and vibrotactile psychophysics to investigate the maturation of the tactile somatosensory system from childhood to young adulthood. 


Winnica Beltrano

Undergraduate Research Student

I am pursuing my Bachelor of Health Sciences in Biomedical Sciences and currently working on the Development of Learning and Tactile Functions in Young Children with Autism Spectrum Disorder (DELTA) project. I am interested in studying whether engaging in a visual task with or without meaningful content has an impact on the brain's response to vibrotactile stimuli in typically developing young adults (age 18-35). I hope that my research will be able to inform methods used for assessing resting state brain activity in future neuroimaging studies.


Amanda Ip, MSc

Research Assistant

I completed my undergraduate degree in Chemical Engineering with a Biomedical Specialization followed by a MSc in Biomedical Engineering at the University of Calgary. My duties primarily involve scheduling visits and collecting data for the Visual-spatial attention development in early childhood study and the Attention in early childhood: risk factors and intervention response study. I also assist with the MRI scanning for these studies as well as supporting the students and postdoctoral fellows in the Bray lab administratively.
