James Evans

Associate Professor, Department of Sociology
University of Chicago

My research focuses on the collective system of thinking and knowing, ranging from the distribution of attention and intuition, the origin of ideas and shared habits of reasoning to processes of agreement (and dispute), accumulation of certainty (and doubt), and the texture—novelty, ambiguity, topology—of human understanding. I am especially interested in innovation—how new ideas and practices emerge—and the role that social and technical institutions (e.g., the Internet, markets, collaborations) play in collective cognition and discovery.

Konrad Kording

Penn Integrated Knowledge Professor
University of Pennsylvania

Professor Kording's research has one single focus, data that matters. Early research in his lab focused on computational neuroscience and in particular movement. But as the approaches matured, the focus has more been on discovering ways in which new data sources as well as emerging data analysis can enable awesome possibilities. The current focus is on Causality in Data science applications - how do we know how things work if we can not randomize?

PJ Lamberson

Assistant Professor
University of California, Los Angeles
