LCD Lab Members

Dr. Charlie Fitzsimmons received a B.S. in Psychology from the University of North Florida and a Ph.D. in Psychology from Kent State University. Dr. Fitzsimmons is a cognitive-developmental psychologist who studies the way people learn, think, and solve problems across the lifespan. Much of his work focuses on how people (mis)understand numbers, their self-regulated learning and awareness of their own knowledge, and the individual differences related to thoughts and feelings about numbers and math. He also studies the way people think about and understand numbers outside of educational contexts, such as when they see health statistics, whether errors can be reduced with visual displays, and how knowledge can be gained through training. Dr. Fitzsimmons is looking forward to expanding his work to study the neural correlates of people’s numerical reasoning.

You can find his most up-to-date CV here. In his spare time, Charlie enjoys watching live music, reading fiction books, and spending time with family, friends, and his two dogs. Although he is originally from southeast Florida, he is looking forward to moving back to Jacksonville so that he can spend more time on or near the ocean.


Hunter Vannaman graduated with a B.S. in Psychology from the University of North Florida. He is currently a graduate student at the University of North Florida in the Master of Science in Psychological Science program working on cognitive psychology research. His primary interest is in the enhancement of learning outcomes in both academic and practical settings, with secondary interests in motivation, self-efficacy, and perceived difficulty. After graduating with his master's, he hopes to pursue a Ph.D.

Hunter currently works with Dr. Sara Davis (primary advisor) and Dr. Charles Fitzsimmons (co-advisor).

Jason Kerr is an Upperclassman at the University of North Florida pursuing a bachelor’s degree in Behavioral Neuroscience. He joined the LCD lab out of a fascination with better understanding the neurological underpinnings of learning and various cognitive processes. His focus is primarily on research design and data acquisition with all things fNIRS, seeking to gain valuable experience exploring the exciting frontier underneath the human scalp. When he’s not busy with coursework or research, Jason enjoys writing down his interpretations of the world, reading various nonfiction, and spending time outdoors. Though he likes to spend most of his free time in the woods, he very much appreciates the air conditioning afforded to him by the lab.
