Hi, I'm Ronald. I help design experiments and technology to explore the ways in which ranking algorithms influence the attitudes, beliefs, and behaviors of individuals and groups. I worked with Robert Epstein to discover the search engine manipulation effect (SEME), conduct research in several psychology-related fields, and build a nonprofit, the American Institute for Behavioral Research and Technology in San Diego, CA. In 2016 I became a student again in the world's first Network Science PhD program at Northeastern University in Boston, MA. Currently, I work with Christo Wilson and David Lazer on reverse engineering ranking algorithms - such as those used by search engines and online marketplaces - and conducting controlled behavioral and computational experiments to analyze their social impact.

Piotr Sapieżyński is an Associate Research Scientist at the Khoury College of Computer Sciences at Northeastern University. He received his PhD from the Technical University of Denmark under the supervision of Sune Lehmann.

I am a fifth year Ph.D student at College of Computer & Information Science, Northeastern University. My advisor is Christo Wilson. I completed my undergradute in Computer Science from School of Science and Engineering, Lahore University of Management Sciences , Lahore, Pakistan. My research interests include systems security and privacy. I have worked on anomaly detection and finding ways to limit service abuse. Currently, I am focused on understanding the ecosystem of online advertisement in order to make it transparent to the end users.

Aniko Hannak is an Assistant Professor in the computer science department of the University of Zürich. She was advised by Alan Mislove and David Lazer. Her work investigates a variety of content serving websites such as Search Engines, Online Stores, Job Search Sites or Freelance Marketplaces. In this quickly changing online ecosystem companies track users' every move and feed the collected data into big data algorithms in order to match them with the most interesting, most relevant content. Since these algorithms learn on human data they are likely to pick up on social biases and unintentionally reinforce them.

David Lazer is Distinguished University Professor of Political Science and Computer and Information Science, Northeastern University, and Co-Director, NULab for Texts, Maps, and Networks. His research focuses on the nexus of social networks, computational social science, and collaborative intelligence. He is an Associate Editor for Social Networks and Network Science, and a reviewing editor for Science. His research has been published in such journals as Science, Proceedings of the National Academy of Science, the American Political Science Review, Public Opinion Quarterly, and the Administrative Science Quarterly.

Alan Mislove is a Professor at the College of Computer Sciences at Northeastern University. He was a post-doctoral researcher at the Max Planck Institute for Software Systems In the summer of 2005, he was an intern at Microsoft Research in Cambridge, UK, working with Antony Rowstron and Miguel Castro. In the fall of 2005, he moved with Peter Druschel to found the new Max Planck Institute for Software Systems, in Saarbruecken and Kaiserslautern, Germany. Alan received a Ph.D. from the Computer Science Department at Rice University in May 2009, under the direction of Peter Druschel and Krishna P. Gummadi. He was the recipient of an NSF CAREER Award in January 2011.

Christo Wilson is an Associate Professor at Northeastern University in the Khoury College of Computer Sciences. His research focuses on algorithmic auditing, which is the process of examining black box systems to understand how they work, the data they use, and ultimately how these algorithms impact individuals. He has examined systems like personalization on Google Search, price discrimination in e-commerce, and surge pricing on Uber. He got his PhD from the University of California, Santa Barbara, working with Ben Y. Zhao. His research is supported by an NSF CAREER award, the Sloan Foundation, and others.
