John Peever, PhD: Principal Investigator

Jimmy Fraigne, PhD: Research Associate

I am interested in understanding how circuits in the brain generate both sleep and wakefulness, and how damage to these circuits can lead to specific disorders. My work in the lab focuses on 2 main questions 1) How does the nervous system couple cortical arousal with the appropriate motor activity to produce meaningful behavior? 2) How is REM sleep and its characteristics generated and controlled? In my spare time, I enjoy food by cooking, finding new restaurants in Toronto, and travelling the world one farmers market at a time. I'm also a flutist and an avid reader of both French and English literature.

Sara Pintwala, PhD candidate

​I began my research career in the Peever lab as an undergraduate thesis student and after enrolled in graduate studies. My research is focused on orexin neurons and cell transplants in the brain. In my spare time I love to cook, bike and travel.

Han-Hee Lee, PhD student

I am a PhD student working in Dr. John Peever's Laboratory at University of Toronto Department of Cell and Systems Biology. My main research interest is to unveil the neuronal mechanism behind the generation and regulation of REM sleep. The main experimental technique that I am using are optogenetics and genetically assisted circuit mapping. As a researcher, my interest is mainly focused on my research but on my spare time I also like singing to relieve my stress.

Russell Luke, PhD student

I am a PhD student studying the link between REM sleep behavior disorder and Parkinson's disease. In my spare time I enjoy trying new foods, attending concerts and watching horror films. I also like to spend my time practicing martial arts and play the trombone. Being from Hong Kong, I look forward to exploring all the unique places Toronto has to offer.

Andrea Bevan, MSc student

I'm a Master’s student and I study the mechanistic link between synucleinopathy and REM sleep behaviour disorder. I'm interested in how α-synuclein, the protein that forms aggregates in synucleinopathic diseases, can play a role in the pathology underlying REM sleep behaviour disorder. Before joining the Peever Lab, I completed a BSc at the University of Western Ontario with an honours specialization in Animal Behaviour (a mixture of psychology and biology). Outside of the lab I enjoy writing stories, painting, and exploring the great outdoors. 

Mohamad Hamieh, MSc student

My research is focused on understanding how sodium oxybate, a drug treatment for cataplexy, interacts with the brain. Outside the lab I'm always ready for a pick up game.

Anita Taksokhan, MSc student

My interest in research began when I did a thesis at Western University on attention using touchscreen chambers. I am now a Master’s student interested in the role of brainstem dorsal pons, projecting to the basal forebrain area, in production of theta oscillations. These theta oscillations are heavily involved in memory and learning of novel experiences. Outside the lab I enjoy exploring ethnic restaurants, having political debates, and sketching.
 

Brittany Dugan, MSc student

Hey there! I'm originally from Ottawa, where I completed my BSc at Carleton University in Neuroscience, with minors in both Statistics and Psychology. My research in the Peever lab focuses on the relationship between RBD and synucleinopathies, as well as factors that may make the REM sleep atonia circuit vulnerable to α-syn pathology. In my free time, I enjoy singing, astrology, playing animal crossing, and learning guitar!

Ziru Wang, Technician

​I finished my Bachelor of Science at the University of Toronto studying a specialist in Health & Disease and a major in Cell & Molecular Biology. My favourite sports are dragon boat and volleyball! During my free time, I love working out, painting and trying out new recipes!
