Research themes
I use network analysis, bibliometrics, text analysis, and computational modeling to study how information and individual choices connect to collective outcomes.
Information in social networks
How people encounter, share, and respond to science information, misinformation, and emerging issues online.
Knowledge and scientific communities
How researchers collaborate, move across borders, and shape the growth and impact of scientific ideas.
Collective behavior and change
How individual choices relate to patterns in public policy, mobility, digital markets, and creative work.
