Caitlin Carew completed her Masters Degree in our lab.
She studied the neuropathology of major depressive disorder. Her project involved an fMRI paradigm designed to examine the neural correlates of rumination and thought suppression. The fMRI paradigm was aimed at understanding the role of the prefrontal cortex in regulation of conscious thought in young women with depression.

Krissy Doyle completed her PhD in our lab.
She studied cross-sensory emotion processing in teens with autism spectrum disorders. The processing of social information involves a network of distributed brain regions, many of which appear to be aberrant in Autism Spectrum Disorders. Because information from the different senses is typically complimentary, cross-sensory integration of social-emotional cues provides information about social judgment that is unobtainable from any one sense in isolation. The objective of Krissy’s study was to investigate the neural circuitry underlying the processing of socially important, affective multimodal cues in high functioning teenage boys with ASD.
The study used individually thresholded emotional face stimuli (% of maximal) in a cross-sensory task that involved the matching of an emotion face and voice combination to an emotion label, to see how successful integration can facilitate the processing of emotion in difficult to detect situations.

Rhandi Senaratne completed her Masters Degree in our lab.
She studied the neurophysiology of bipolar depression. Her project involved an fMRI paradigm designed to examine the neural correlates of recollection memory and reward processing. In addition, Rhandi used Magnetic Resonance Spectroscopy to examine biochemical markers of neural function in patients with Bipolar Disorder.

Caitlin completed her bachelor of science in Genetics at McMaster University. She is currently studying medicine at the University of Toronto.
Caitlin worked for us as a research assistant in a clinical trial looking at the effect of the probiotic strain, Bifidobacterium longum, on anxiety and depression in patients with irritable bowel syndrome. Many studies suggest that psychiatric co-morbidities in IBS patients develop as a consequence of gut inflammation and are therefore amenable to therapy with specific probiotic strains such as B. longum. For this clinical trial, our lab is collaborating with a gastroenterology lab at the McMaster Farncombe Family Digestive Health Research Institute in order to examine changes in IBS symptoms, biomarkers and gut microbiota in addition to functional changes in the central nervous system as a result of administration of this probiotic strain of bacteria.

This was done in collaboration with fellow graduate student Ellis Freedman, and undergraduate student, Rita Abdel-Backi, under the supervision of Dr. Geoffrey Hall. In many places in the world, access to expertise in assessment and treatment of psychological disorders is limited or non-existent. The IMPACT was developed as an interview to be delivered by non-experts in these populations. 
Additionally, Amber is interested in the examination of biological signatures in children with Autism Spectrum Disorder, such as genome-wide associations, starting at the level of the synapse (synaptic functioning, excitation-inhibition balance) to local circuits and brain connectivity. From these biological signatures, Amber is working on a project that will use a novel approach of clustering genotypic profiles (biologically driven common pathways in ASD) through machine learning and factor analysis. These biological signatures will be used to develop a computerized assessment to target heterogenous Autism phenotypes.
Amber’s research interests include the interaction between pre- and post-natal mental health and its contribution to child development, the development of psychometric assessments, global mental health,  accessibility to assessment and treatment, neuroimaging (fMRI, DTI, Cortical thickness, Functional connectivity), Autism, Genomics/Epigenetics.
