We know that when you move your head in an MRI scanner, this can incorrectly show up as brain activation. Do we sometimes falsely attribute activation that we see in an MRI scanner to patterns of brain activity, when it's just the head jerk that someone makes when they know they've made a mistake in the task we've asked them to do?

Evidence for the existence of such a phenomenon, also known as the "Whoops!" response, has already been established (by Epstein and colleagues, 2007). It has implications for the accurate interpretation of MRI data in all contexts where participants are performing tasks in which they can make errors. My project, constructed under Jordan's supervision, provides such an opportunity to study it further. Our research involves looking at the link between task-correlated motion, motion artifacts, and error responses in a mock MRI setting.

Broadly, my academic interests lie at the intersection of cognitive neuroscience and neurobiology with diseases and disorders of the central nervous system. In addition to the PopMem lab, I am a part of Queen's Neurobiology of Anxiety lab, where I am working on a study that examines changes in patterns of neuronal activity in rat anxiety models. I also have two summers' field experience in South Africa, (one of which was subsidized by a Queen's grant,) at research and education reserves dedicated to behavioural and conservation ecology projects.

At Queen's, I am pursuing a Psychology degree with a minor in Life Sciences, although I also have the requirements for a World Languages minor. In my spare time, I like to ski, play ice hockey, and write poetry--which I sometimes perform at poetry slams.
