Jinci is currently a junior at Macalester College majoring in neuroscience and on the pre-medicine track. She started volunteering in the RAD lab because she wants to immerse herself in a clinical research setting and see the direct application between research and medicine. She is interested in learning more about the pathology of mood disorders from different perspectives, such as looking at anatomy of the brain through neuroimaging or looking at emotion regulation by the HPA axis. Her goal is to attend medical school and being able to serve under-served communities as a clinical psychiatrist.

Abby is currently a senior studying neuroscience at the U. She started volunteering in the RAD lab because she wanted to learn more about clinical research and is interested in the adolescent population. Abby is especially interested in the effects of early life stress on adolescent neurobiological development and the development of psychiatric disorders. In the future, she hopes to attend graduate school to get her Ph.D. in clinical psychology. Her end goal is to become a child psychologist and work with children who have experienced early life stress.


Dawson Hill's Photo Dawson Hill

Hi my name is Dawson Hill and I’m a junior studying Psychology here at the U. I became interested in the RAD Lab initially because of the research related to MRI imaging and how we look for indicators and signs of disorders based on brain structure. Additionally, I like being a part of the RAD Lab because of the team atmosphere involved and how everything comes together with many different contributions. As of right now, my goal is to become an adolescent psychiatrist working in a residential mental health treatment facility.
