Area of expertise

Cognition and Brain Sciences

I study the behavior and the underlying brain mechanisms of how people recognize visual things, such as faces, facial expressions, melanoma, etc. using psychophysics, eye tracking and EEG. I also design and develop training tools to help people improve the visual skills that are relevant to them. For example, I developed a training protocol that utilizes the state-of-the-art science and technology in machine learning and adaptive training algorithms to improve the users' accuracy (from 52% to 75%) to detect melanoma within 2 hours of training. I am also involved in the development and evaluation of training programs that help children with autism to recognize and produce facial expressions, and to recognize faces.
