Justin Riddle

Justin Riddle is an Assistant Professor at Florida State University leading the Riddle Lab, where his research investigates neural mechanisms of cognitive control and their disruption in psychiatric disorders using multimodal neuroimaging and brain stimulation techniques.

Education

• Ph.D. from University of California, Berkeley (2018)

Research Interests

The Riddle Lab focuses on how electrical brain activity (EEG) and hemodynamics (fMRI) underlie cognitive processes like attention, working memory, and decision-making. Through transcranial magnetic stimulation (TMS) and transcranial alternating current stimulation (tACS), the lab probes causal neural mechanisms of cognitive control and their impairment in psychiatric illnesses, aiming to bridge basic neuroscience with clinical applications.

Current Activities

• Recruiting graduate students for Fall 2026

Dr. Riddle emphasizes academic integrity and effective mentorship in training future scientists. His commitment to scientific innovation drives the lab's interdisciplinary approach to understanding goal-directed cognition.
