Dr. Trujillo holds degrees in mathematics (B.S.), physics (M.S.) and psychology (B.S., M.A., Ph.D.) from the University of Arizona, Tucson, AZ, USA. His research interests include the cognitive neuroscience of human perception, learning, memory, attention, and consciousness, as studied via behavioral, electroencephalographic (EEG) and functional magnetic resonance imaging (fMRI) techniques. Dr. Trujillo investigates both the normal performance and development of these cognitive functions, as well as the changes in these functions with sleep deprivation and sleep restriction. Dr. Trujillo’s research with the Langlois Social Development Lab involves using EEG and behavioral methods to investigate the neurocognitive basis and development of facial attractiveness.
