I am in my third year of my BA here at Dal, majoring in Psychology with a minor in Esoteric & Occult traditions. I will be working along side of Ph.D. student Mandy Hagen on her Dose Response Alcohol project which looks at how the negative self-relevant cognition of individuals with clinical depression is negatively reinforced by consuming different doses of alcohol. It is my intention to continue with the MAAC lab for an honours project in my 4th year as well. My ultimate goal is to become a practicing Clinical Psychologist. My main clinical interest is in how various beliefs and narratives about the world, others, and ourselves, exert a causal force on our mood, cognition, perception, and behaviour. I am very grateful for the opportunity to work in the MAAC lab this year and I look forward to gaining lots of valuable research experience
