Postdoctoral Fellows

Anna Blumenthal
BA in Psychology, Minors in Classical Studies & Philosophy, Drew University
MS in Cognitive Science University of Trento & SISSA, Italy
PhD in Behavioral and Cognitive Neuroscience, University of Western Ontario
Anna is co-supervised by Meg Schlichting and Michael Mack. She grew up in Colorado and New Jersey, and did her graduate work in cognitive neuroscience in northern Italy and then in Ontario at Western. Broadly, She is interested in how the hippocampus and surrounding medial temporal lobe structures contribute to perception, learning, and memory. At UofT, she is excited to combine neuroimaging and computational modeling to understand the link between episodic and semantic memory in the developing brain. In her free time, she loves going hiking and camping with Alfred (the handsome fellow in the photo), reading fantasy/sci-fi, and traveling.

Emily Heffernan
B.Sc. (Eng) in Electrical Engineering, Queen’s University
M.A. in Experimental Psychology, University of Toronto
Ph.D. Student, University of Toronto
Emily completed her B.Sc. in electrical engineering at Queen’s University. After spending a year working in technical sales at Microsoft, Emily chose to return to academia to pursue her passion for learning and teaching. Emily is interested in combining computational models and neuroimaging data to better understand how we learn as our brains develop. She is also part of the Collaborative Specialization in Engineering and Psychology. Her research is fueled by large amounts of tea and frequent yoga sessions.

Melisa Gumus
Hon. B.Sc. in Neuroscience and Mathematics, University of Toronto
M.Sc Student in the Institute of Medical of Science, University of Toronto & Tanz Centre for Research in Neurodegenerative Diseases
Melisa is investigating the link between cognitive outcomes and structural/functional brain changes in post-concussion and CTE patients in her masters, being supervised by Dr. Carmela Tartaglia and collaborating with Dr. Mack. She is also part of the DTI team at the Mack Lab, that studies the interaction between differences in white matter tracts and learning performance during rapid categorization using computational models. She has been part of the lab since the beginning and previously served as a lab manager. She believes that math can solve anything, even the complexity of the human brain.

Xinyaun (Zoe) Wu
University of Toronto, 2nd year Undergraduate specializing Psychology and majoring Nutritional Science
Volunteer Undergraduate Researcher
Zoe is a former ROP student at the Mack Lab and is now a volunteer RA. She is really excited to explore the field of psychological research through the opportunities provided at Mack Lab. Her project is on recognition-induced forgetting, a phenomenon that people tend to forget the first object they learn from a category by learning another object in the same category. Outside of her academic life, she is a huge fan of Broadway musicals.

Yongzhen (Dory) Xie
University of Toronto, 4th Year Undergraduate
2020-2021 Individual Project Student
I am a 4th-year student who specializes in psychology. I am interested in the neural mechanisms underlying concept acquisitions, as well as the influences of concepts on memory and perception. I am currently doing a research project on how memory consolidation and concept dimensions affect people's memory for concepts and items. In my spare time, I enjoy making digital art, tickling my cat, and observing insects.
