My goal is to boost human learning and performance by developing and applying formal models of cognition. I am interested in producing software that enables individuals to learn and perform tasks efficiently and effortlessly. My approach draws on methods from machine learning and theories from cognitive science in order to construct robust psychological models that characterize the computational challenges faced by an individual attempting to complete a task. My research lies at the interface of human learning, machine learning, and computer-assisted decision making.
My research has predominantly focused on
helping individuals categorize visual images. I have
approached this objective from two perspectives: decision
support and efficient training. Decision support enables
expert-like levels of performance—without training—by
exploiting ordinary but powerful human visual capabilities.
Efficient training promotes the discovery of the visual
features necessary to correctly categorize the images.
Both approaches leverage a latent space representation of
human-perceived similarity, which we refer to as a
Current limitations in visual task performance motivate my primary research questions:
