Odysseus is a first-year Ph.D. student in the Cognition program at the University of Iowa. His current research explores how humans and pigeons differ in their representation of perceptually similar stimuli. From rocks and medical images to simple shapes and colors, Odysseus employs a wide variety of stimuli and tasks. On his free time, Odysseus enjoys listening to and playing classical trumpet repertoire, spending time with loved ones, and eating good food.

Leyre Castro received her Ph.D. from the University of Deusto (Bilbao, Spain). She began her research in experimental psychology studying the associative basis of causal learning in humans. She has published studies on causal learning, categorization, attention, same-different discrimination, memory, metacognition, unsupervised learning, figure-ground perception, task switching and cognitive flexibility, with both humans and pigeons. She is interested in the similarities and differences among species at behavioral, neural, and computational levels.
