Lab Alumni

Hanne K. Collins

Hanne is an Assistant Professor of Management and Organizations at UCLA Anderson. Her research examines effective listening. In particular, she studies the conversational behaviors that ensure people are both being and feeling heard in order to foster interpersonal connection. In one stream of research, she studies these dynamics in the context of interpersonal conflict. Her work leverages rigorous scientific methods and cutting edge tools including a combination of experiments and computational social science techniques such as natural language processing. Hanne completed her Ph.D. in Organizational Behavior at Harvard Business School in 2024.

Charles Dorison

Charlie is an Assistant Professor of Management at Georgetown's McDonough School of Business. Prior, he was a Postdoctoral Fellow at Northwestern's Kellogg School of Management. He completed his Ph.D. at Harvard Kennedy School (Decision Science Track) in 2020.

Charlie's research integrates theory and methods from behavioral science and organizational behavior to examine how individuals navigate social environments fraught with conflict. His primary line of research models how observers evaluate targets who do (vs. do not) fall victim to cognitive biases. This work generates testable predictions regarding when and why apparent errors can confer reputational benefits from observers. In his second line of work, he examines disagreement over strongly-held attitudes (e.g., politics), especially misperceptions of conflict counterparts and interventions to overcome these misperceptions. In a final line of work, Charlie investigates how emotions influence health decision-making.

Molly Moore

Molly is a Lecturer in Economics at Washington University in St. Louis. She received her Ph.D. in Public Policy and her undergraduate degree in Economics, both from Harvard University.

Her research focuses on how impression management and observer expectations of behavior align with–and influence–people's decision making. She is especially interested in how this applies to the domains of selective exposure, disagreement, and gender. She teaches a variety of courses including: Making Decisions, Game Theory and Social Behavior, Microeconomics and Behavioral Economics. Outside of academics, she has competed as a USRowing National Team and CrossFit Games athlete.

Christopher Higgins

Chris is working as a research assistant at the Minson Conflict and Collaboration Lab where he assists on multiple projects related to disagreement in a conversation.

Martha Jeong

Martha is an Assistant Professor in the Department of Management at Hong Kong University of Science & Technology (HKUST). Her current research program focuses on decision-making and communication strategies. Martha explores our how subjective experience and attitudes toward the “decision-making experience” affect how we make decisions and how we feel about the decisions afterwards. She studies how we use information on how decisions were made to infer decision-making quality and influence decision-maker evaluations. Martha’s research aims to tackle the question: How can we structure organizational decision-making so that individuals not only make accurate decisions but feel motivated to make the best decisions and feel accountable for the decisions they make? In her research stream on communication, Martha looks at whether we adopt effective communication strategies in goal-driven communications, such as when we negotiate, seek feedback, or promote ourselves.
