Research Interests

My research focuses on understanding the real-world ramifications and underlying neural mechanisms of visual attention. I study radiologists’ behavior to understand why errors are sometimes made, with the goal of using what we know about attention help reduce the number of errors committed. I also study the neural mechanisms that underlie our ability to represent information using electroencephalograph (EEG). The capacity of visual attention is limited, and my lab uses a variety of methods to study the ramifications of this fact on behavior in a variety of settings.

Keywords: Attention, working memory, medical image perception, EEG, ERPs, Eye-tracking.

Overview of one of our recent studies.

Opportunities For Students

I am currently seeking motivated graduate and undergraduate students to assist with a variety of current research projects which involve studying:
1). The role of visual attention in diagnostic radiology.
2). The electrophysiological underpinnings of visual attention and working memory.
3.) The interactions between searching through memory and searching through visual space.

Contact me directly for more information!
Graduate students would ideally have some experience with EEG, eye-tracking, or working closely with MDs / medical professionals. Some programming experience (Matlab-Psychtoolbox, ERPLAB, EEGLAB, Presentation, PsychoPy...E-Prime) is a definite plus.
