Research Interests

My research interests are broad-ranging from cognitive psychology to neuroethics. I am particularly interested in studying real-world decision-making in potentially vulnerable populations.

My current work is studying how those with cognitive impairments make decisions to participate in scientific research. I am passionate about the scientific method and applied statistics, which has led me into new and exciting scientific areas.
