James Evans

Associate Professor, Department of Sociology
University of Chicago

Phone: 773-834-3612

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.

Roger Guimera

Professor, Universitat Rovira i Virgili, Spain

Phone: 34-977-558-661

Roger Guimerà (Barcelona, 1976) graduated in Physics at Universitat de Barcelona in 1998, and obtained a PhD in Chemical Engineering from Universitat Rovira i Virgili in 2003. He then moved to Northwestern University, where he worked as a postdoctoral fellow and, later, as a Fulbright Scholar. In 2008 he became a Research Assistant Professor at Northwestern’s department of Chemical and Biological Engineering, before accepting his current position at ICREA.

Eszter Hargittai

Professor, Institute of Mass Communication and Media Research
University of Zurich

Eszter Hargittai is a Professor in the Institute of Mass Communication and Media Research at the University of Zurich where she heads the Media Use and Society division. Eszter's research focuses on the social and policy implications of digital media with a particular interest in how differences in people's Web-use skills influence what they do online.

Cristian Huepe

Research Scientist & President, CHuepe Labs Inc.
Adjunct Professor, ESAM Northwestern University
McCormick School of Engineering and Applied Science

Dr. Huepe obtained his PhD in Physics at the Ecole Normale Superieure in Paris, after completing undergraduate studies in his native Chile.  Dr. Cristian Huepe is a physicist conducting research in complex systems, nonlinear dynamics and statistical physics.  He has worked in various subjects throughout his career, including: superfluidity, Bose-Einstein condensates, a toy cosmology model, finite-time singularities, spatiotemporal chaos, defect dynamics and Faraday waves.  His current research focuses on the dynamics of collective motion and complex networks.

PJ Lamberson

Dean Malmgren

Data Scientist, Datascope Analytics

Dean Malmgren is a co-founder and data scientist at Datascope Analytics, a data-driven consulting and design firm in Chicago, where he has helped clients like P&G, Daegis, and Thomson Reuters use data to solve the right problem. When he’s not brainstorming data-driven concepts or writing code to analyze/visualize data, he enjoys DIY projects, cooking, playing sports (e.g., running, cycling, golf), reading, and a hearty dose of parenthood. Dean received a BS from the University of Michigan and a PhD from Northwestern University, has spoken at conferences like Strata, and published peer-reviewed research in journals like Nature, Science, and PNAS that have been featured in places like TIME, Wired, and US News & World Report.

Said Business School, University of Oxford

Phone: +44 (0)1865 288502

Felix’s research has addressed the dynamic properties of large-scale collaboration and manufacturing networks, common structural features in organizational and ecological networks, the impact of imitation mechanisms on the emergence of cooperation, the robustness of ecological networks, and the spread of innovations in online social networks. These individual projects are linked by broader theoretical concerns, including the need to develop a more dynamic conception of network robustness and resilience, and an interest in identifying generative mechanisms that give rise to generic structures of cooperation.
