Dr. Junchul Kim

2005~2010 - Postdoctoral Research Fellow, Genetics Department, Harvard Medical School, USA.

2005 - Ph.D. in Molecular biology and Biochemistry, Simon Fraser University, Canada.

1996 - B.Sc. in Biology, Yonsei University, Seoul, Korea.

We are interested in understanding how the brain is wired for processing information from the environment to generate approach-avoidance behaviours, with a particular focus on neuronal circuits that modulate behaviours associated with anxiety and schizophrenia. Using the mouse as a model organism, we are currently using various genetic approaches for neuron manipulation, including opto- and pharmacogenetics. We hope that the resultant findings yield new insights into the pathophysiology of schizophrenia and anxiety-related disorders and potentially provide new therapeutic targets for their treatment.

Paul Whissell

paul.whissell@gmail.com

Dept. of Psychology

I am a neuroscientist with a long-standing interest in exploring the neural mechanisms of anxiety, depression, novelty preference and memory. For the past several years, I've intensively studied the very important role that specific GABAA receptor subtypes and GABAergic cells (interneurons) play in these behaviors. Recently, I've also begun to examine the role that cannabinoids (including the ever-controversial THC) play in the development of GABAergic networks and behavior. Outside of the laboratory, I'm also a teacher, active volunteer, runner and weight-lifter. I enjoy good films, terrible food and mediocre Toronto sports teams.

Sabrina Nawaz

sabrina.nawaz@alumni.utoronto.ca

Dept. of Psychology

Hi. I'm Sabrina! 4th year PhD. My hobbies include photography, painting, and cooking :) I also throw awesome lab parties :P my research involves investigating the function of serotonin projections from the dorsal raphe to the ventral hippocampus and their role in stress and anxiety. 

 

Afif Aqrabawi

afif.aqrabawi@mail.utoronto.ca

Dept. of Cell and Systems Biology

I joined the Kim Lab as an undergraduate at UofT. Since then I have been interested and working on the organization and function of the rodent olfactory system. In particular, my research focuses on the role of the anterior olfactory nucleus in early olfactory processing and odour-guided behaviours. When I am not daydreaming about the AON, I am usually in the gym, cooking, or reading a book. 

 

Janine Dominique Cajanding

j.cajanding@mail.utoronto.ca

Dept. of Cell and Systems Biology

Research areas include neurodevelopmental risk factors: prenatal infection, chronic cannabinoid activation; perisomatic gaba neurons: parvalbumin, CCK; epigenetic profiling; behavioural neuroscience; transgenic mouse lines.  

What draws me in to science? The pursuit to discover an objective truth, the appeal of scientific rigour and competition, the ability to share your ideas and findings to a community and the possibility of making an impact on a clinical level. Outside the lab I enjoy photography, fitness, and good eats.

Dept. of Cell and Systems Biology

I am a Master's student with neuroscience and cell & molecular biology background. My project is all about the neural circuitry associated with stress response. I'm interested in the hypothalamic circuitry and wish to understand the limbic integration/modulation of stress and anxiety behavior.

On my spare time, I like to draw, read, and play lacrosse (or try to be active). I also try to travel as much as I can. I love doing science because it's fun! It's awesome to learn/discover new things and be challenged.

Ikram Khan

ike.khan@mail.utoronto.ca

Ikram received a Bachelor of Science degree in Physiology and Psychology from the University of Toronto. He has a strong interest in understanding the physiological basis of neuropathology and how current research methods can be extended into the clinical realm. Under the supervision of John Yeomans, Ikram conducted an independent study exploring the possible use of Designer Receptors Exclusively Activated by Designer Drugs (DREADDs) in treating Parkinson’s Disease. His current research goals are to better understand interneuron-mediated pathology using DREADD manipulations.
