The Cultural Dynamics Lab

Director

Joshua Conrad Jackson

Joshua Conrad Jackson

Assistant Professor of Psychology, Harvard University

Joshua Conrad Jackson’s research focuses on the intersection of cultural evolution and psychology. He studies how people’s psychologies change as societies become larger, more diverse, more economically developed, and more connected to each other. He has applied this lens to many different societal changes, from early state formation to the modern rise of robotics and social media, and to many different psychological processes, from moral psychology to emotion to religious and secular belief systems. Underlying all these studies is a deeper interest in how our minds adapt to a rapidly changing world.

Professor Jackson has published papers in Science, Nature, Nature Human Behaviour, Proceedings of the National Academy of Sciences, and Journal of Personality and Social Psychology. He has written for the Huffington Post, LA Times, and Scientific American. He has won the Early Career Award from the International Association for Conflict Management, the Sage Emerging Scholar Award from the Society for Personality and Social Psychology, and the Dissertation Award from the Society for Experimental Social Psychology. Before joining Harvard, Professor Jackson was the Neubauer Family Assistant Professor at the Booth School of Business at the University of Chicago.

Our lab, around the world

We study how minds and societies shape one another, and the lab itself draws on many societies. Each point below marks where someone in the lab is from, current members and alumni alike. Select a point to see who it belongs to, then follow the link to their entry further down the page.

Lab members

Lab Managers

Hanying Yao
Lab Manager

Hanying is interested in studying beliefs and identities across social, political, and cultural contexts. She is particularly interested in foundational psychological and social processes (e.g., categorization, belief updating, coordination) and how they shape polarization and intergroup dynamics, especially as emerging societal phenomena (e.g., globalization, social media, AI) transform the transmission of social information. Her research uses large-scale surveys, experiments, computational modeling, NLP, and network analysis.

Shirley (Xueyan) Zhang
Lab Manager

Shirley is interested in the cognitive processes that support social inference and behavioral adaptation, and in how these processes scale up through social interaction to produce collective phenomena such as shared representations, social norms, and cultural change. Methodologically, Shirley is particularly interested in combining formal and computational models, especially agent-based models, with clean experimental designs that isolate and test the psychological mechanisms proposed by those models.

Postdoctoral Researchers

Dan Medvedev
Postdoctoral Researcher

Dan is interested in how the incentive structures embedded in people’s environments shape how they think and act. Dan is also curious to understand how values are changing around the world and how globalization and increasing wealth are contributing to that change.

Dan received a PhD in Behavioral Science at the University of Chicago Booth School of Business and was the 2024-2026 Dispute Resolution Research Center Postdoctoral Research Fellow at the Northwestern University Kellogg School of Management. Dan’s research has been published in Nature Human Behaviour, Nature Communications, and Psychological Science.

Shen Li
Postdoctoral Researcher

Shen’s research focuses on historical psychology and language change using diachronic texts, with the goal of uncovering fundamental regularities in mind and language shared by people across time and space.

PhD Students

Ugur Mert Yasar (Umy)
PhD Student

Umy studies norms, rules, and culture through an institutional lens, using computational models as well as lab and field experiments.

Shiyun Cao
PhD Student

Shiyun is interested in how human adaptation to social ecology shapes distinct norms and values across cultures. She is particularly interested in the role of institutions, including ancient and modern forms, in cultural evolution. Shiyun is also drawn to cultural evolutionary mismatch, where once-adaptive cultural traits become maladaptive as ecological conditions change.

Meriel Doyle
PhD Student

Meriel studies how culture and technology shape psychological change over time. She is particularly interested in meaning-making and how certain kinds of societal transformation can erode our sense of purpose and well-being.

Yuanze Liu
PhD Student

Yuanze studies collective psychology and cultural evolution, with a focus on how interactions among individuals give rise to collective patterns of thought and behavior and how these patterns change over time. He is particularly interested in how psychological and cultural dynamics respond to changes in social ecology, including new institutions and technologies such as AI, and how these changes can be harnessed to improve collective outcomes.

Geshi Yeung
PhD Student

Geshi received a B.A. in Cognitive Science and Computer Science from the University of Pennsylvania. Geshi’s research involves exploring how social identity and network structure shape collective intelligence and emotions, as well as how to leverage psychological insights to improve human-AI collaboration. Before starting the Ph.D., Geshi worked as a research coordinator at the Stanford Social Neuroscience Lab.

Part-Time Research Assistants

Lekshmi Radhakrishnan
Research Assistant, Harvard University

Lekshmi is interested in how the interpretive frames people inherit shape the way psychological distress is recognized and treated, where that produces misclassification, and who ends up without care. She approaches these questions from comparative evolutionary neuroscience of social bonding and primatology on one side, and from psychiatric residential care and mental health access research on the other.
