SHORT BIO

With a hybrid background in physics, computer science, film, and media, I deploy social computing to measure, understand, and forecast the collective behavior of connected crowds in large-scale sociotechnical systems like peer-to-peer platforms. My current research develops empirical and theoretical methods to support creativity and predict success in culture industries, identify expressions of collective intelligence and opportunities for innovation in crowdsourcing communities, as well as detect shared misconceptions and biases in online capital markets. My work uses an interdisciplinary data-driven approach and builds on techniques from network science, machine learning, statistics, and exploratory visualization. I developed and teach the ‘Cultural Analytics’ graduate course that is designed to train students for careers at the intersection of creative occupations and Data Science. I serve on the editorial board of PLOS One. My current research is funded by the National Science Foundation through a CISE CRII award.

CURRENT STUDENTS

PROSPECTIVE STUDENTS

  • I advise graduate students in two PhD Programs: Technology and Social Behavior and Media, Technology, and Society. Prospective graduate students should apply through one of these programs.
  • I am always looking for outstanding undergraduates and Master's students to get involved in research. Prospective students are encouraged to send me an email with their inquiry.
