About The Person Project

We are The Person Project. We are scientists at Princeton University, and we are fascinated by the internal mental world and all of the thoughts, perceptions, and emotions it comprises. We are driven to understand the external social world and all of the social connections we share. Thank you for contributing to our research.

Our Research

The Person Project aims to understand why people do what they do. Our goal is to test specific hypotheses about human social cognition and behavior. We want to reach people from all different backgrounds, locations, and abilities, and include them in the latest psychology research.

Our Community

The Person Project helps you learn about you. Choose from dozens of surveys and studies to learn more about you, your mind, and your relationships. After participating in each study, you will receive immediate, personalized feedback, and further information about the research topic that you are contributing to.

Diana I. Tamir

Diana I. Tamir, Ph.D.

Principal Investigator

Dr. Diana Tamir studies how people think about their own minds and the minds of other people. She received her Sc.B in cognitive neuroscience from Brown University, her Ph.D. in psychology from Harvard University, and her postdoctoral training at Stanford University. In 2015, she joined Princeton University as an Assistant Professor of Psychology and as director of the Princeton Social Neuroscience Lab.

Stacey Sinclair

Stacey Sinclair, Ph.D.

Principal Investigator

Dr. Stacey Sinclair studies how people's social group members affect their relationships with others. She graduated from Stanford University with a joint degree in Psychology and Economics and received her Ph.D. from University of California, Los Angeles. She is currently a Professor of Psychology and Public Affairs at Princeton University, where she co-directs a lab with Dr. Nicole Shelton.

Nickolas M. Jones

Nickolas M. Jones, Ph.D.

Postdoctoral Research Associate

Nickolas' research rests at the intersection of social psychology and technology. He is interested in how people express emotion and leave behavioral traces on social media and smartphones. He uses big data analytics to capture how people respond to large-scale negative events (e.g., collective trauma) and to understand how everyday technology-use relates to social psychological and personality phenomena. He received his B.A. (2009) and M.A. (2011) from California State University, Fullerton and his Ph.D. from the University of California, Irvine (2018).

Mihir J. Gandhi

Mihir J. Gandhi, M.Sc.

Research Specialist

Mihir is interested in understanding how the human brain can be modeled to perform complex tasks by combining computational modeling, behavioral experiments, brain imaging, and software engineering to build better algorithm designs for computer software. He is interested in machine learning and wants to explore how computational advertising and social interactions affect human actions and thoughts. He completed his B.S. in Computer Engineering from NMIMS University in Mumbai, and his masters in Computer Science from Northeastern University.
