Malvina Skorska Ph.D., Postdoctoral Fellow

Malvina is a Brain Canada - Kids Brain Health Network postdoctoral fellow working on a brain imaging project of adolescents with gender dysphoria in relation to hormone therapy. She received a PhD from the Department of Psychology at Brock University (St. Catharines, ON) in October 2016. Her master's and doctoral work focused on biological/physical correlates (e.g., height, facial structure, birth weight, fraternal birth order) related to sexual orientation. In addition to the brain imaging project, she is continuing to work on projects related to the development of sexual orientation in the BIG lab. In her free time you can find her outdoors, reading, visiting wineries, and traveling.


Lindsay Coome, Ph.D. Student

Lindsay is a PhD student in the B.I.G. lab. Her research interests span the fields of biological, evolutionary, and cross-cultural psychology. Her thesis investigates the science of sexual orientation and gender identity. Mostly, she is interested in the evolutionary, genetic, hormonal, and immunological bases for the development of third gender identities in a non-Western culture, Thailand.

Diana Peragine, Ph.D. Student

Diana is an NSERC Doctoral Scholarship Holder with an interest in social neuroscience, feminist research, and science outreach. She studies sexual development from an experiential perspective, emphasizing how one’s social position “writes on the body” to alter reproductive physiology and behavior. Her Masters research used a unique rodent system to characterize neural correlates of social competition in female-dominated groups, and clarify neuroendocrine mechanisms by which cues conveying subordinate status can delay puberty for life. This work underscores the importance of including females in research on aggression and intrasexual competition, and highlights a new role for GnIH in mammalian reproductive maturation. Diana’s dissertation research explores the developmental psychobiology of human sexual motivation, asking how sex and social position (i.e., gender) steer brain development to produce differences in sexual desire and sensation.
Off the clock, Diana enjoys bringing science out of the lab and into the streets with Science Rendezvous and ROM Friday Night Live, and has founded several outreach initiatives, including the SRSF STEM Education Scholarship, the Sexuality Interest Network (SIN), and SEXposium Science Outreach Conference.


A. Natisha Nabbijohn, M.A. Student

Natisha is a SSHRC award holder and is currently working on her M.A. in Psychology. Her graduate work focuses on children's appraisals of gender variant expression. Her other research interests include studying how various social, environmental, and biological factors influence mental health. In particular, much of her previous research experience focused on childhood gender expression and its relationship with psychological well-being. 



Miao Qian, Graduate Student Collaborator

Miao is a Ph.D. student in the lab of Dr. Kang Lee at the Ontario Institute for Studies in Education (OISE). Her collaborations with the BIG Lab focus on understanding how children's social preferences are shaped by others' race, gender, and gender expression. This work takes place cross-culturally in Canada and China.


Joanna Matthews, B.Sc. Candidate and Research Assistant

Joanna is a second-year undergraduate student pursuing a double major in Biology for Health Science and Psychology. She is particularly fascinated how sociocultural factors and parenting styles influence child mental health and gender non-conformity. Her current research task focuses on finding the implications of children’s books based on gender non-conformity. In her spare time, Joanna enjoys outdoor activities, poetry, and learning about different cultures.


Adhm Zahran, Research Assistant

Adhm is a third-year undergraduate student at U of T pursuing a Double Major in Biology for Health Science and Psychology. He is especially intrigued by the underlying, and sometimes competing, biological and sociological factors that affect gender identity formation. He is currently a research assistant under the supervision of Ph.D. student Lindsay Coome studying the correlates of sexual orientation. In his spare time, Adhm likes to go to the gym and play video games. 


Allana Braga, ROP Student

Allana is a third-year undergraduate student studying Forensic Anthropology. Her work in the Big Lab focuses on physical development correlates of sexual orientation. 


Nicole Preddie, IRP Student

Nicole is a third-year undergraduate Psychology student. She is working on projects examining how gender and age influence children's toy preferences.


Simran Isani, ROP Student

Simran is a second-year undergraduate student in Biology and Psychology. She is working on a study examining children's appraisals of others based on their gender and gender expression. 


Jeffrey Loch, IRP Student

Jeffrey is an undergraduate Psychology student at UTM. His work in the BIG Lab focuses on understanding the relationship between gender expression and self-harm and suicidal ideation in children. 


Boting Gao, IRP Student

Boting is an undergraduate Psychology student. She is studying the effects of culture on interpretations of facial emotional expressions using emojis.


Lindsey Thurston, Research Assistant

Lindsey completed her BSc in Biology with a minor in Psychology at The University of Waterloo and her MSc in Neuroscience at Queen's University. Her work in the BIG Lab involves working with a large dataset examining sexuality and gender in Thai participants.
