Paula M. Di Nota, PhD

Dr. Di Nota is a Post-doctoral Fellow in the Health Adaptation Research on Trauma (HART) Lab at the University of Toronto Mississauga. She is currently investigating the neurophysiological mechanisms underlying training and complex motor learning in police populations, as well as the influence of occupational stress on the mental health and well-being of police and other first responders. Her dissertation research examined learning-induced changes to brain activity using behavioral, fMRI, and EEG measures.

Monica Ghabrial, PhD

Monica Ghabrial, Ph.D. (she/her) is a Health Psychologist, currently working as a CIHR Postdoctoral Fellow in Epidemiology and Biostatistics at Western University Schulich School of Medicine and Dentistry. Dr. Ghabrial is a former student of Dr. Andersen and they continue to collaborate on a number of important projects. During her time in the HART Lab, Dr. Ghabrial’s dissertation research primarily examined stress, health, and resilience among Queer and Trans People of Color, with additional projects on biculturalism, visibility, and wellbeing among plurisexual/bisexual People of Color and community and resource development for women with HIV. Through an intersectional, strengths-based framework, she developed and validated the first measure of positive attitude toward identity for Queer People of Color, the Queer People of Colour Identity Affirmation Scale, and used that scale to investigate the link between identity affirmation and cardiovascular adaptivity to stress. Dr. Ghabrial’s dissertation was selected as a top 5 finalist for the 2022 CAGS/Proquest Distinguished Dissertation Award.

In her current position, Dr. Ghabrial is working on two studies of trans health across Canada. She also runs a website dedicated to reporting research on Queer and Trans health, www.queercarekit.com.

Jennifer F. Chan, MA

Jennifer F. Chan, MA, is a PhD student in the Health Adaptation Research on Trauma (HART) Lab at the University of Toronto, Mississauga, supervised by Dr. Judith P. Andersen. She completed her Honours Bachelor of Science at McMaster University in Psychology, Neuroscience & Behaviour, and her Master of Arts in Psychology at the University of Toronto. Her interdisciplinary research interests include health, stress, neuroendocrinology, inflammation, and biofeedback.

Her research focus involves measures of psychosocial, physiological stress, and mental/physical health in first responders; previous projects have explored occupational stress, the prevalence of mental health symptoms (e.g., PTSD, depression, anxiety), and cortisol dysfunction in police. She has also completed research at SickKids’ Peter Gilgan Centre for Research and Learning, studying MEG resting state neuroconnectivity of Canadian Armed Forces personnel diagnosed with PTSD. Her current dissertation research investigates how healthcare professionals’ experienced stress and coping during the COVID-19 pandemic influences mental and immune health via salivary biomarkers of inflammation.

Jen is also involved in education and science communication throughout the greater Toronto area. She is a course instructor and teaching assistant at UofT, as well as a co-founder of UofT SPRINT (Summer Psychology Research Initiative)- a program dedicated to providing high school students from groups typically under-represented in STEM free and accessible hands-on experience in Psychology research. She has also collaborated with and is an invited speaker for groups including the Royal Canadian Institute for Science, the Story Collider, and the Canadian Multicultural Inventors Museum.

Amanda Dawson

Amanda Dawson is a Psychology BSc student at the University of Toronto Mississauga. Her research interests involve investigating alternative forms of therapy to mitigate aggression in at-risk persons and violent offenders through the manipulation of oxytocin levels. She wishes to address her research on an intersectional scale towards diverse populations, BIPOC, LGBTQ+ persons within the prison industrial complex (PIC). Her goal is to promote rehabilitative over punitive treatment, mitigating the stigmatized association of criminality and mental health.

She will be working on the Horticultural Therapy Project (HTP) supervised by Dr. Judith Andersen. She will be exploring horticultural therapy as a peer support program among undergraduate students. Amanda will be facilitating this project alongside a team of collaborators to organize and monitor the success of an alternate form of therapy at the University of Toronto Mississauga.

Konstantinos Papazoglou

Konstantinos Papazoglou, MA, is a psychology PhD (2018) and Vanier CIHR scholar at the University of Toronto supervised by Professor Judith P. Andersen. After obtaining his master’s degree in mental health counseling at New York University (NYU) as Onassis foundation scholar in 2010, he worked as a clinician with military personnel (2006-2008) and police cadets in Athens, Greece (2010-2012) and inmates in correctional facilities of the State of New York (2009-2010). He served as a uniformed police officer in Athens, Greece for almost 14 years (1998-2012) eventually obtaining the rank of police captain.

His work focuses on the conceptualization of complex police trauma, first respondents’ resilience, police health promotion, and community-based trauma prevention through culturally relevant interventions. He has presented his work throughout North America and Europe (e.g., American Psychological Association, Canadian Psychological Association, Academy of Criminal Justice Sciences, International Society for Traumatic Stress Studies, etc.).


Christopher Zou

Christopher Zou, MA, is a psychology PhD (2017) at the University of Toronto.   He completed his undergraduate and Master’s degree at the University of Toronto, and is in his senior year of the doctorate program. He is currently working on multiple research projects with Dr. Judith P. Andersen at the HART lab, which includes (but not is limited) to the following:

Bullying and Health. Chris’ first line of work with Professor Andersen involves exploring the effect of experiencing adverse childhood events (e.g., parental divorce, bullying) on long-term health and well-being. He is especially interested in examining how minority membership (particularly sexual minority membership) can influence the impact of bullying on health.

Coming Out Project. Chris’ second line of work examines the underlying assumptions surrounding the “coming out” experience of sexual minorities. He is interested in examining the different definitions of “coming out” across researchers and the general public, and understanding the impact of coming out on health and well-being of individuals who belong to sexual minority groups. He hopes that by identifying some of these assumptions about “coming out”, we can better assist individuals who are going through this difficult process.
