Knowledge Lab Team

James A. Evans

Director, Knowledge Lab; Professor, Sociology, University of Chicago; Faculty Director, Masters Program in Computational Social Sciences; External Professor, Santa Fe Institute

James Evans is Director of Knowledge Lab, Professor of Sociology, Faculty Director of the Computational Social Science program, and member of the Committee on Conceptual and Historical Studies of Science at the University of Chicago. I am also an External Professor at the Santa Fe Institute. His 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. He is especially interested in innovation–how new ideas and technologies emerge–and the role that social and technical institutions (e.g., the Internet, markets, collaborations) play in collective cognition and discovery. Much of his work has focused on areas of modern science and technology, but he is also interested in other domains of knowledge–news, law, religion, gossip, hunches and historical modes of thinking and knowing. He supports the creation of novel observatories for human understanding and action through crowd sourcing, information extraction from text and images, and the use of distributed sensors (e.g., RFID tags, cell phones). He uses machine learning, generative modeling, social and semantic network representations to explore knowledge processes, scale up interpretive and field-methods, and create alternatives to current discovery regimes. His research is funded by the National Science Foundation, the National Institutes of Health, DARPA, Facebook, IBM, the Sloan Foundation, Jump! Trading and other sources, and has been published in Science, PNAS, Nature Human Behavior, Nature Biotech, American Journal of Sociology, American Sociological Review, Social Studies of Science, Administrative Science Quarterly, PLoS Computational Biology and other journals. His work has been featured in Nature, the Economist, Atlantic Monthly, Wired, NPR, BBC, El País, CNN and many other outlets.

Austin Kozlowski

Graduate RA, University of Chicago

I am a doctoral candidate in the Chicago sociology department. My research focuses on the questions of how belief systems are structured and why certain ideas “go together.” By applying state-of-the-art computational methods, I attempt to shed new light on these age-old questions from the sociology of knowledge and culture.

 At Knowledge Lab, I have developed ways to use word embedding models to discover cultural categories and associations in text. This work has culminated in a recent article, co-authored with James Evans and Matt Taddy, published in the American Sociological Review. I am now engaged in a project with James Evans and Hyunku Kwon that explores how AI can be harnessed for social scientific analysis.

 Before coming to the University of Chicago, I earned my BA in Sociology at the University of Michigan and worked as a research associate with the Chitwan Valley Family Study at the UM Institute for Social Research. During my time at Michigan, I conducted research on the effects of agricultural technology adoption among subsistence farm households in Nepal.

Jamshid Sourati

Jeremiah Milbauer

Graduate Student, Carnegie Mellon University

I am an artificial intelligence researcher, software engineer, and occasional writer. I am interested in exploring the relationships between language, knowledge, and society. At Knowledge Lab, I work on projects that use machine learning and natural language processing techniques to discover concept structures and worldviews across a variety of data sources.

Before joining Knowledge Lab, I spent time as a research assistant with John Lafferty, Ben Zhao, and John Goldsmith working on a variety of natural language processing projects. On the engineering side, I did an internship at Alphabet’s autonomous vehicle division Waymo (at Google X), and was the machine learning lead at Simmer (a YCombinator-backed startup). My writing has been featured by the Berkman-Klein Center for Internet & Society, and The Economist.

I grew up in New York City (where, as a matter of survival, I quickly learned my way around both gallery openings and giant rats). I graduated from the University of Chicago in 2019 with degrees in Computer Science and Philosophy.

He is also interested in the representation of learning on the multi-layer network and predicting the performance of collaboration with deep learning tools.

He also works as the TA for the AI & Society workshop at Nanjing University and the TA of Graph Neural Network Paper Club at SwarmAI. He now leads an online nestedness network research group to understand organizational structure and the fate of the organization.

Likun Cao

Graduate Student, University of Chicago

I am currently a first-year Ph.D. student in the sociology department at the University of Chicago. My research interests are sociology of knowledge and organizational study, and I use computational tools to explore those fields. Specifically, I am interested in the interaction between the economic structures and the human knowledge system. How are technological and cultural knowledge produced in modern capitalism? And how does this knowledge reshape the institutional background where it comes from? In my research, I try to trace the social processes and mechanisms of this interaction.

Before coming to Chicago, I received a B.A. and an M.A. in sociology from Tsinghua University, China. My previous work concerns the social network of venture capital firms in China and the dynamics of its evolution. Currently, at knowledge lab, I apply word embedding techniques on data about business strategies of start-ups in the U.S., trying to figure out how the business landscape is formed and transformed by technological innovation, and how this social process on the macro level shapes social lives and division of labor of millions of employers and employees.

Eamon Duede

Simon Schachter

Graduate student, University of Chicago

Simon Yamawaki Shachter is a Ph.D. student at the University of Chicago Sociology Department. He is interested in philanthropy and the nonprofit sector, especially how public and private systems of funding alter field-level outcomes. He utilizes historical, statistical, and computational tools to understand how public and private efforts to serve the public good influence each other. He is particularly drawn to research that exposes when these, often well-intentioned, efforts work to perpetuate certain forms of inequality while seeking to alleviate others. 

Prior to coming to the University of Chicago, Simon received a B.S. in Computer Science at Stanford University. In the Bay Area he worked for several private philanthropic foundations and founded YCore, a San Francisco-based non-profit that brings young professionals together to support equity-building work in their local communities.

Adarsh Mathew

Masters student, University of Chicago

I’m a computational social scientist working to straddle the worlds of sociology, network science, and machine learning. I’m interested in exploring the relationship between networked identities and the propagation of knowledge: how individuals and communities work to form and evaluate epistemological practices; the role their networks and identities play in this process; the effect of hierarchies and narrative structures in this dialectical process.

At the Knowledge Lab, I work on projects that examine ideology and conflict in online communities, using networks and language processing methods to describe user and community behaviour, especially in contentious and radical political communities. My research interests also span the philosophy of science and computing, formal network epistemology, and the interplay between algorithmic decision-making and the structural imperatives that make data collection possible. I’m currently pursuing an MA in Computational Social Science at the University of Chicago.

Before my time at the University of Chicago, I worked for a tech firm based in the Bay Area, and as an international development consultant. I have a Masters’ and Bachelors’ degree in Industrial & Systems Engineering from IIT Kharagpur, which served as my introduction to statistical learning, and optimization & heuristic methods. I call Hyderabad home, and have a soft corner for speculative science fiction (Ted Chiang & Ken Liu) and high fantasy, along with general soccer nerdiness.
