I work in the interdisciplinary area of computational perception and cognition - at the intersection of computer science and cognitive science. I focus on the human and computer processing of visual data, which spans computer vision, human vision and memory, machine learning, human computer interaction, and visualization. At the cross-section of these research areas are applications to user interfaces, visual content design, and educational tools. By studying how humans attend to, remember, and process visual stimuli, the goal of my research is to contribute to cognitive science, while using this understanding for building computational applications.

Image Saliency and Importance

Saliency is a information measure of images that can be used to determine the most important image parts. Applications include image summarization and thumbnailing, user interfaces, and object detection. Many new saliency models are developped every year, and progress is improving rapidly. I am currently running the MIT Saliency Benchmark, one of the most popular datasets for evaluating saliency models. At the same time, I'm investigating new ways of crowdsourcing attentional data in order to train models to automatically discover the most salient or important image regions.

A computational understanding of image memorability

Images carry the attribute of memorability: a predictive value of whether the image will be later remembered or forgotten. Understanding how image memorability works and what it is affected by has numerous applications - from better user interfaces and design to smarter image search and education tools. This research aims to answer: to what extent is memorability consistent across individuals? How quickly can an image be forgotten? How can we model the effects of image context on memorability (can we make an image more memorable by changing its context)? Can we use people's eye movements and pupil dilations to make predictions about memorability?

What makes a visualization memorable, comprehensible, and effective?

This line of work aims to understand how people interact with and perceive data visualizations - multimodal visual and textual presentations of data or concepts, including graphs, charts, and infographics. This research aims to answer: which visualizations are easily remembered and why? What information can people extract from visualizations? How can we measure comprehension? What do people pay the most attention to?
