"Science" Paper:
Social Media for Large Studies of Behavior

Over 1 billion people use social media every day. When researcher want to utilize these data to study human behavior on global scale several issues arise. Do people on online platforms represent society? Do people behave online like they do offline? Do our scientific methods fit social media data? These challenges are discussed in a new article authored by Derek Ruths from McGill Universtiy and me. The article is published in Science.

Studying Social Networks

Studying Social Networks:
A Guide to Empirical Research

Studying Social Networks provides a concise, comprehensive introduction to the process of empirical network research. Students and practitioners new to social research will find easily understandable learning goals, numerous examples, and helpful exercises all in one compact volume. The authors have integrated different disciplinary perspectives, while stressing the importance of substance-specific orientation while studying networks. Scholars will find Studying Social Networks a helpful tool not only for teaching, but also as a guide for their own empirical research.
