Christopher Bowie

Christopher Bowie, PhD, C.Psych.

Dr. Bowie is a clinical psychologist and Professor in the departments of psychology and psychiatry at Queen’s University.  He primarily studies neurocognition and functional disability in severe mental disorders like schizophrenia and mood disorders such as depression and bipolar disorder. Neurocognition refers to the functions of the brain that allow us to perceive and process information and guide our actions. When we talk about attention, memory and problem solving, we are referring to neurocognitive functions. Functional disability refers to difficulties performing in areas of life such as academics, working, living independently, and socializing with others.


Supervised Graduate Students

Mike Best

Mike Best, Fourth Year PhD Student

Mike graduated with a B.Sc. (Hon.) in the department of Psychology at Queen’s University and is interested in understanding and improving social functioning for people with psychosis. Mike’s Master’s research examined neurophysiological biases to hearing the speech of someone with schizophrenia, and uncovered an early processing bias that may be related to the social exclusion that many people with schizophrenia face. In addition to his Master’s research, Mike has been involved in research to improve the understanding and measurement of stigmatizing attitudes towards schizophrenia, and he developed a mental health stigma reduction program for student leaders at Queen’s. Currently, Mike is using electroencephalographic (EEG) techniques for two lines of research: 1) to examine neurophysiological changes that occur after people with mental illness engage in a cognitive training program; and 2) to examine the neurophysiological effects that being socially excluded has on people with psychosis.

Melissa Milanovic

Melissa Milanovic: Fourth Year PhD Student

Melissa graduated from the University of Guelph with a B.Sc. (Hon.) in Psychology and minor in Neuroscience. During her undergraduate studies she conducted a thesis using an animal model to investigate the role of the nicotinic cholinergic system in learning visuospatial associations. Melissa’s Master’s research examined the role of self-efficacy in the deployment of functional skills in everyday life for individuals with major depressive disorder (MDD). In her PhD thesis, Melissa is investigating factors involved in the motivation to engage in cognitive remediation for MDD.

Tanya Tran

Tanya Tran: Third Year PhD Student

Tanya completed her B.Sc. (Hon.) in Psychology at Queen’s University. She is interested in studying cognitive-affective processes and how they might go awry in schizophrenia and depression. For her undergraduate thesis, Tanya developed an observational global rating system to evaluate maternal emotion coaching in mother-daughter interactions and examined its role in adolescent emotion regulation and depressive symptomatology. At present, Tanya is using a computer-based implicit learning task to examine how attentional biases for emotional stimuli and reward sensitivity interact with severity of anhedonia in a depressed population. She is looking forward to developing lines of research throughout her graduate studies that may identify or better characterize dysfunctional cognitive-affective processes as risk factors of depression

Stephanie Woolridge: Second Year MSc Student

Stephanie graduated with a B.A. (Hon.) in the department of Psychology at Queen’s University with a minor in sociology. She completed her undergraduate Honours thesis in the CPD lab, focusing on attentional bias in depression. In this study, Stephanie developed a novel training paradigm which utilized eye-tracking technology to reduce the commonly held bias in depression to preferentially focus one’s attention on negative information. As a Master’s student, Stephanie plans to continue to study cognitive biases in depression, with a particular interest in treatment-focused research. In the coming years, she hopes to extend her research to explore neurocognitive and social cognitive enhancement in psychosis.

Melinda Kinney

Melinda Kinney: Second Year MSc Student

Melinda completed her B.Sc. (Hon.) at the University of Toronto as a psychology specialist and was drawn to the work of the CPD lab through serving as a clinical interventionist at the Centre for Addiction and Mental Health. There, she facilitated Cognitive Remediation and a novel brain stimulation technique on a study that aims to prevent cognitive decline among individuals with mild cognitive impairment and a history of depression. Previously, Melinda was involved in research at Northwestern University that examined the trajectory of client change in psychotherapy, and post-secondary curriculum design research at the Michener Institute for Education. Melinda hopes to further our understanding of cognitive processes in mood disorders and their impact on other areas of functioning, as well as ways to optimize the use of cognitive remediation with this population.

Chelsea Wood-Ross

Chelsea Wood-Ross: Second Year MSc Student

Chelsea graduated from Queen’s University with a B.Sc (Hon) in Psychology. Chelsea completed her undergraduate thesis in the CPD lab where she studied avoidance in major depressive disorder. In this study, Chelsea used electroencephalographic (EEG) and developed a game that asked individuals to select their desired difficulty level as a way to examine how individuals with major depressive disorder avoid challenging tasks. Chelsea is interested in using experimental research to study cognitive impairments in major depression and what features of depression may act as barriers to treatment and daily functioning..
