About me
I am a post-doctoral fellow in the Face Perception Research Lab under the supervision of Dr. Alice O'Toole.


Research Interests
My research focuses on the perception and recognition of human faces. Human faces are complex stimuli, providing important information for face identification, categorization (e.g., race, gender, and age), and social interaction (e.g., head-direction, eye-gaze, facial expression). With this vast information, the human brain efficiently filters out the relevant information based on the task at hand (e.g., identifying a familiar face across different appearances). I study the complex neural codes underlying these face recognition tasks, using behavioral, functional neuroimaging, and pattern-based classification techniques.
