I am an Associate Professor in the Information School at the University of Washington and currently a visiting associate professor at the University of California, Berkeley, School of Information. I co-founded the Center for an Informed Public. I study the Science of Science and worry about the spread of misinformation. My laboratory consists of the millions of scholarly papers and public posts about science. I develop knowledge discovery tools to facilitate and study science, with a particular interest in how sociological and economic factors drive and slow the evolution of science.
