Research
Behavioral Science of Data Visualization
The same data can lead to different conclusions depending on how it is shown. I study why—and how chart design shapes what people understand, trust, believe, and do.
My work brings together consumer behavior and information design. Through behavioral experiments, surveys, and quantitative modeling, I examine which design choices matter, for whom, and under what conditions.
I aim to bring this approach to teams developing dashboards, reports, and digital products—helping them test their assumptions and make design decisions grounded in how their audiences interpret and use information.
