George A. Alvarez
George A. Alvarez is a Harvard psychologist whose research connects human visual cognition with computer vision and deep neural networks. Born in Honolulu and raised in Watsonville, he studied at Princeton, Harvard, and MIT before joining Harvard's psychology faculty; a 2008 study found that people could recognize details across nearly 3,000 images. In 2024, he coauthored two studies on self-supervised visual categories and how 224 vision models predict brain activity. In spring 2025, he spent a sabbatical semester as a Kempner visiting scholar; as of October 2026, he is Harvard's Fred Kavli Professor of Neuroscience, co-directs the Vision Sciences Laboratory, and focuses on the intersection between human vision and machine vision.

By 2008
Studies at Princeton, Harvard, and MIT
He is born in Honolulu and grows up in Watsonville, then studies at Princeton as an undergraduate, at Harvard for graduate study, and at MIT for postdoctoral work. By 2008, he is an assistant professor of psychology at Harvard after postdoctoral work in MIT's Department of Brain and Cognitive Sciences.

2008
Memory for thousands of images
In 2008, he coauthors a study in which participants view nearly 3,000 images and later choose exact matches from three kinds of image pairs. Participants recall 92%, 88%, and 87% across the tests, showing detailed visual long-term memory for thousands of objects.

Self-supervised visual categories
In September 2024, he coauthors a study that uses self-supervised contrastive learning to form category-selective units for faces, bodies, scenes, and words. These units predict neural responses in corresponding human visual-cortex regions.

Comparing 224 vision models
In October 2024, he coauthors an analysis of 224 vision models that finds different architectures and task objectives achieve near equivalent brain predictivity when other factors are held constant. Variation across visual training diets has the largest and most consistent effect on brain predictivity.

2025
A Kempner research sabbatical
In spring 2025, he spends a sabbatical semester as a full-time visiting scholar at the Kempner Institute. The spring 2025 article describes plans for him to work with fellows Binxu Wang and Thomas Fel on a project that uses deep neural networks to generate images for probing neurons in real monkey brains.

As of October 2026
Linking human and machine vision
His ongoing work focuses on the intersection between human vision and machine vision. He draws technical ideas from computer vision into models of human vision and applies human vision science to study deep neural networks and develop more robust machine-vision systems. As of October 2026, this remains his research focus.

As of October 2026
Professor and lab co-director
As of October 2026, he is the Fred Kavli Professor of Neuroscience in Harvard's Department of Psychology and an affiliate faculty member at the Kempner Institute. He is also a Professor of Psychology at Harvard and co-director of the Vision Sciences Laboratory.
