DR. ELIZABETH HAYDEN

Professor, Lab Director

I am a Professor of Psychology and Principal Investigator of the Brain and Mind Institute at the University of Western Ontario. My research takes a developmental psychopathology approach to understanding the biological and contextual pathways to adaptive and pathological mood dysregulation, with a particular focus on understanding which children are most vulnerable to negative outcomes following exposure to early adversity.  This research program necessitates a multimethod approach, and incorporates methods such as observational measures of child emotionality (i.e., temperament) and the early home environment, structured clinical interviews, psychophysiological approaches, imaging, and genetic methods. This work, which has spanned the entirety of my research career, takes a lifespan approach and uses longitudinal designs to examine relevant processes in children and adults, as well as patient and nonpatient samples.  As an independent investigator or coinvestigator, I have received generous research support from multiple funding agencies to develop this program of research, including support from NARSAD, Canadian Institutes of Health Research, SSHRC, NSERC, and NIMH.

HALEY GREEN

Ph.D. Candidate

Haley is a Ph.D. candidate in Clinical Psychology. She completed her B.Sc. in Child Development and Psychology with Highest Honors at Vanderbilt University and her M.Sc. in Clinical Psychology at Western University. Her Master's thesis examined predictors of intraindividual variability and mean trends in adolescents' internalizing symptoms over the first year of the COVID-19 pandemic. She is interested in using advanced analytic approaches (e.g., item response theory, network analysis) to examine the psychometric properties of psychopathology assessment tools, as well as examining how parenting, temperament, and stress  contribute to the development of internalizing symptoms in youth.

DR. OLA MOHAMED ALI

Ola defended her PhD dissertation titled “Childhood Irritability: A developmental psychopathology perspective” in 2023. She completed her Pre-Doctoral residency at the St. Joseph’s Healthcare Hamilton. Ola’s research interests include understanding interactions between children’s developing temperament/personality and the early caregiving environment to shaping later outcomes, with a specific focus on childhood irritability. She has a particular interest in applying her developmental psychopathology training in youth mental health. She now holds a temporary position as a Psychologist in Supervised Practice at the Rob Joyce Children’s Health Center in Hamilton, Ontario, after which she plans to complete a clinical Post-doctoral fellowship at Stoney Brook University, New York.

DR. MATTHEW VANDERMEER

Matt defended his PhD thesis "Neuroimaging Depression Risk in a Sample of Never-Depressed Children" in 2021. He completed his Pre-Doctoral residency with the London Clinical Psychology Residency Consortium. With a background in cell & molecular biology, counselling psychology, and psychosis research, Matt used his doctoral training to merge his interests in biology and psychopathology. Specifically, Matt is interested in understanding neurobiological vulnerabilities to psychopathology. In addition to interests in temperament/personality, internalizing disorders, and traumatic stress, he has increasingly applied modern neuroimaging techniques to answer questions regarding the mechanisms which may lead to psychopathology. Matthew is now working as a postdoctoral fellow in the Department of Psychology at Queen's University

DR. YULIYA KOTELNIKOVA

Yuliya successfully defended her doctoral thesis in June 2016, and completed her predoctoral residency at IWK Health Centre in Halifax, NS (child and adolescent clinical psychology track). She then took a position as a Postdoctoral Research Associate at the Center for Advanced Measurement of Personality and Psychopathology, University of Notre Dame. Her doctoral research focused on developmental psychopathology of depression by examining pathways from the early vulnerability factors to emerging depressive symptoms via intermediary mechanisms. Studies of the nature and structure of child temperament using multi-method and multi-informant approaches were also a part of her doctoral research program. Her post-doctoral research focused on expanding the alternative approach to conceptualizing personality disorders from the perspective of impairments in personality functioning and pathological personality traits. Yuliya now holds a faculty position at the University of Alberta.
