Cianna Bedford-Petersen studies personality in the context of online social networks. Her primary line of research explores the relationship between social media and mental health through Twitter behavioral data and self-reports. Her secondary area of research focuses on how chronic illness communities utilize social media. Within Type 1 diabetes communities on Twitter, she uses topic modeling techniques to understand what topics are being talked about and social network analysis to explore the structure of the community.

Grace Binion studies how key affective processes consequential for transdiagnostic risk for psychopathology (e.g. affect recognition, affect perspective taking, emotion regulation) develop in preschool children, as well as how early interpersonal experiences influence this development. Additionally, her research examines the measurement tools and methods employed in these areas (developmental, clinical, and affective science), with particular interest in how they influence replicability and cumulative science.

Cory Costello is interested in personality (who we are), reputation (what other people think, say, and hear about us), and social networks. This includes personality measurement, longitudinal stability and change of personality, accuracy of reputations formed in different contexts (e.g., face-to-face interactions, online, and gossip), and how our personality and reputation relate to our behavior and connections with others online. Cory’s methodological interests include structural equation modeling, mixed effects modeling, machine learning, and social network analysis.

Bradley Hughes studies interpersonal perception—the impressions and judgments made of others during interactions. Specifically, he is interested in the influence of a person’s personality on others (e.g., elicitation, reciprocity) and how this in turn influences perceptions of and behavior. A second area of interest is the improvement of psychological science. To this end, he is currently examining how people update beliefs based on conflicting scientific evidence.

Rita Ludwig is interested in directly applying scientific research to the development of programs that can improve people’s lives. She uses methods such as neuroimaging, psychometrics, and machine learning to study how to transform maladaptive habitual thoughts in behaviors into beneficial ones. Her current line of work focuses on developing evidence-backed interventions to help poor Americans break the cycle of poverty.

My research is primarily focused on questions about emotion and culture. For example, I study how violations of cultural norms can lead to different emotional reactions, or how cultural scripts can lead to differences in experience and expression of emotions. I’m also interested in the recent developments in statistics and research methods, and closely follow the discussions about open science and replicability. You can learn more about my research interests here, and see a list of my publications here.
