Keithan Ducre

I am the Lab Manager of the Vision and Perception Neuroscience Lab at Stanford University, where I completed my bachelors in 2025 (Psychology with honors). I am also a Predoctoral Research Fellow at the Stanford Institute for Research in the Social Sciences. I co-lead a psychophysics project that aims to model and predict human size perception of objects in the natural world and explain the moon illusion —a visual illusion that has stumped thinkers such as Aristotle and Ptolemy. Additionally, I coordinate a study on the neural and functional development of the visual system. I collaborate with a team of researchers to collect MRI and eyetracking data on children, teens, and adults to link one's everyday visual environment to brain development.

I am chiefly interested in the intersection of brain and behavior with a particular interest in the visual perception system. Currently, I am building the neuroimaging skills that will complement my experience in behavioral designs in future graduate school research where I hope to merge both behavioral and neural data to further study human perception through naturalistic paradigms.
