His educational background in psychology and philosophy have provided him with a solid understanding of human behavior and the intricacies of the human mind. He is deeply interested in the field of neuroscience and is eager to further his education by pursuing a Ph. D. in Neuroscience research.

Andrew Turgeon (Research Assistant 2022-2023)

Andrew graduated from Smith College in 2021 with a B.A. in Biology and a minor in Psychology. His previous research experience focused on how impulsivity moderates the relationship between ADHD and bulimia symptoms. He is interested in pursuing a degree in Clinical Psychology.

Jessica Faraca (Research Assistant 2021-2022)

Jessica graduated from Washington State University in 2020 with a B.S. in Neuroscience and a minor in Psychology. Her previous research experience focused on neural mechanisms of pain modulation and animal models for opioid withdrawal. She is interested in addiction research exploring relationships between reward seeking behavior and the development of substance use disorders.

Jackson Lee (Summer Research Intern 2022)

Jackson Lee is a rising third year undergraduate student studying neuroscience at Amherst College. His past research experience includes working with zebrafish to study the effects of hormone treatment on signal transduction in noise damaged hair cells. In the future, he is interested in pursuing a career in both medical treatment and research. 

Enedina Zepcan (Research Assistant, 2022)

Enedina, from Bosnia and Herzegovina, graduated from Lewis and Clark college in 2021 with a B.A. in Psychology and minors in Neuroscience and Hispanic Studies. Her previous research focused on the effect of bilingualism on executive functions in young adults; prosocial behavior in children; and the effect of gut microbiom dysbiosis on the brain and behavior of children. She is interested in pursuing a degree in Behavioral Neuroscience.

Kate Barnes (Research Assistant, 2022)

Kate graduated from Colorado College with a B.A. in Computational Cognitive Science. Previously, she conducted Data Science research analyzing factors contributing to the popularity of online media. She is interested in applying Computer Science methods to Psychology research, particularly in computational models of emotion. She also has a background in community building with non-profits, and she values bridging the gap between research and community.
