Short CV
robert dot rozeske at utoronto dot ca
I received my BA in Psychology at St. Olaf College and my MA and PhD in Psychology & Neuroscience at the University of Colorado-Boulder. During my graduate work in Steven F. Maier’s lab I focused on how behavioral control over stress produced enduring trans-situational resilience. I investigated how the medial prefrontal cortex interacted with the serotonergic dorsal raphe nucleus to confer stress resilience.
As a postdoc, I joined Cyril Herry’s lab at INSERM located at the University of Bordeaux. I investigated a circuit composed of the medial prefrontal cortex and periaqueductal gray that regulates contextual fear discrimination behaviour. I later joined Mark P. Brandon’s lab at McGill University to study how the hippocampus represents different contexts to produce fear discrimination using calcium imaging techniques.
Outside of the lab I enjoy cooking, playing ultimate, running, hiking, and playing music.

I completed my BSc at the University of Toronto St. George as a Neuroscience Specialist and Psychology Major. During that time, I participated in research which fostered my interest in the neuroscience of psychological disorders and investigating their treatments. Currently, I am pursuing a MSc at the Rozeske Lab, using a mouse model of PTSD to investigate neuronal activity in the prefrontal cortex during fear behaviour and experiential factors that may modulate fear extinction. Beyond the lab, I enjoy reading psychiatry/neurology case studies, rock climbing, and the great outdoors.
Liv ENGEL
Wilfred and Joyce Posluns Sex and Gender doctoral fellow

I received my BA in Psychology at Reed College and am now a 1st year PhD student in the Psychology department at the University of Toronto. In my undergraduate research I examined the role of estrogen receptors in ethanol withdrawal-induced anxiety. I then became a lab manager in the Saunders lab at the University of Minnesota and investigated how distinct dopamine projections from the midbrain to the dorsal or ventral striatum conferred different motivational properties to Pavlovian cues. In my graduate work, I will be focusing on hippocampal and prefrontal circuits of contextual fear expression and extinction. Outside of the lab I enjoy biking, film photography, and brewing beer.

I am a second-year undergraduate student double majoring in neuroscience and molecular biology, immunology, and disease and a minor in astronomy and astrophysics. I am interested in behavioral neuroscience and neural networks involved in cognitive functions. My free time is spent working at a pharmacy and studying pharmacy on the side, and playing with my kitten and budgies.
Ameen SALIM
Undergraduate student
alameen dot salim at mail dot utoronto dot ca
I am currently a second-year student completing a Specialist in Cognitive Neuroscience and a Minor in Psychology. I am interested in the neural mechanisms behind perception, intrapersonal and interpersonal behaviour, and both chemical and psychological methods of altering or improving cognitive function. Outside of school and the lab, I spend my time reading, writing, and working out. I also love learning about human history, sociology, music, and evolutionary biology.
Megan Lozzi
CGS master’s fellow

I completed my BA in Psychology at Concordia University. Throughout my degree I worked in the Iordanova lab, studying the neural substrates underlying various forms of Pavlovian fear and reward learning. I later joined the Fulton lab at the University of Montreal as a research assistant, contributing to projects examining the interaction between nutrition, neural processes, and affective behaviour. During my PhD, I will look at how the prefrontal cortex, hippocampus, and periaqueductal grey contribute to contextual fear learning and the generation of defensive behaviours in mice. In my free time I like being outside, cycling, and learning about paleontology.

I am a third-year undergraduate student pursuing a co-op specialist degree in cellular & molecular neuroscience. I am interested in cellular mechanisms behind neurodegenerative diseases and the application of calcium imaging recordings and optogenetics to investigate on neural circuit-dysfunction-related diseases like Parkinson’s. Outside of school, I enjoy doing my workout routine, cooking, swimming, and playing music!
Winnie HSIANG
Undergraduate student

I am a third-year Computer Engineering student, majoring in Software Engineering with minors in Artificial Intelligence and Bioengineering. I have a strong passion for interdisciplinary learning and enjoy exploring diverse research areas. In my leisure time, I am a pianist, and music plays a significant role in my life. My favorite composer is Scriabin—if you haven't heard of him, he is amazing!
Nithilan SURESH
Undergraduate student

I am a third-year Industrial Engineering student minoring in Artificial Intelligence and Engineering Business. Fun fact about me: I only learned how to code after I started my first-year in university. Since then, I have developed a passion for working with data and programming. Outside of school, you can find me playing video games and coaching soccer.
Claire SHAO
Undergraduate student
claire dot shao at mail dot utoronto dot ca
I am a third-year student, double majoring in Mathematics and Neuroscience. My academic interests lie in neural networks, modeling signals through coding algorithms, and cognitive neuroscience. I find the interdisciplinary approach to learning and application particularly fascinating. Outside of school, I enjoy reading and cooking. I also love the atmosphere of libraries and have volunteered at a local library.
Alex CHEN
Undergraduate student

I am a third-year student specializing in cellular and molecular neuroscience. My research interests mainly focus on decoding neural signals and understanding how manipulation of brain circuitry can induce behavioral change. I’m a strong enthusiast of late imperial Chinese history and antique collections, and I spend most of my spare time reading, writing, practicing calligraphy, and traveling whenever possible.
