Amy R. Krosch, Ph.D.   cv  |  email


Amy studies how social and economic factors shape the way we see, think and feel about, and make decisions for others. She was born and raised in rural Minnesota and received a B.S. in Psychology from the University of Wisconsin - Madison, where she investigated intersectionality and discriminatory judgments with Professor Colleen F. Moore. Next she moved to New York City and researched intertemporal choice and risky decision making at Columbia University with Professors Elke U. Weber, Eric J. Johnson, and Bernd Figner at the Center for the Decision Sciences. She then completed a PhD at New York University with Professor David Amodio, where she examined economic scarcity effects on discrimination through multiple levels of social perception - from mental representations to neural encoding. She most recently worked as a post-doc with Professor Mina Cikara at Harvard University investigating social value and reinforcement learning. Amy joined the Cornell psychology department as an Assistant Professor in July, 2016, and is excited to get back to the woods.

Mikaela Spruill   email


Mikaela is a first year graduate student who studies perceptual bias at the intersection of race and gender. Her research focuses on revealing the ideological barriers to social justice that exist for minority groups. She works to understand how our beliefs about the overarching American system amplify discrimination and inequality in order to uncover interventions that can aid in reducing bias and addressing disparities in America. Mikaela earned her MA in experimental psychology from Wake Forest University, and her BS in neuroscience from The College of William and Mary. She enjoys going to concerts, doing yoga, and watching football.


Stephanie Tepper         email


Stephanie Tepper is a graduate student in the Krosch Lab studying how people make decisions in ways that influence high-level social inequalities. She focuses on questions related to perceptions of inequality, resource allocation decisions, and interventions to promote equal outcomes. Prior to starting graduate school, she worked at the Center for Advanced Hindsight conducting research to improve financial decision-making through behavioral intervention. Stephanie received a B.A. in Psychology & Neuroscience from the University of North Carolina at Chapel Hill. Outside of the lab, she enjoys browsing Ithaca's local markets and playing music.


Rachel King                  email


Rachel is a first-year Ph.D. student in social psychology working with Drs. Amy Krosch and Katherine Kinzler. Before coming to Cornell, Rachel earned a B.A. from UW-Madison, where she researched children's social cognitive development with Dr. Kristin Shutts. Rachel is broadly interested in the development of social group concepts and biases. In the Krosch Lab, Rachel designs social interventions to reduce adults' intergroup biases. Outside of the Krosch Lab, Rachel researches the development of beliefs about socioeconomic status and social mobility, as well as children's early social reasoning about food. She is also designing studies to evaluate adults' and children's understanding of social inequality, privilege, and merit. Outside of the lab, Rachel enjoys spending time with her 13-year-old English Mastiff, Cedric.

Jesse Walker is a 4th year graduate student at Cornell who studies biased judgment. His work has examined biases in consumer behavior, strategic decision making, everyday social interaction, and musical preferences. In the Krosch Lab, he studies barriers to overcoming inequality by investigating the effect of minority advancement on judgment and behavior. His newest hobby involves finding creative ways to sleep that fit the unpredictable schedule of his one year old son.    


Xi Shen                         email


Xi mainly researches implicit impression formation and updating and judgments about trustworthiness. In the Krosch Lab, she studies how people's perception of facial trustworthiness could be influenced by threatening situations. Xi received her B.S. in China and M.A at NYU without leaving psychology. She enjoys traveling and searching on Yelp for good and bad restaurants. 

Christopher Monteiro             email


Christopher’s research focuses on the relationships between ideology and low-level cognitive mechanisms, such as memory and perception. His current work focuses on the relationship between the age of ideas and perceptions of their veracity, and on the relationship between ideology and social perception. Christopher earned his BA in psychology and MA in conflict resolution at the University of Massachusetts, Boston. He is interested in the effects of changes in the economy and political ideology on memory and beliefs regarding scientific information and also in carnism, the ideology that supports using non-human animals for food, and it’s relationship with prejudice toward human social groups.

Steve Strycharz           email


Steve studies how perceived time scarcity (i.e., feeling as if one does not have enough time to do the things that need to be done) influences life satisfaction as well as everyday judgments and decisions. One project explores how life satisfaction is differentially influenced by subjective busyness (i.e., perceived time scarcity) and objective busyness (i.e., number of hours spent on work-related activities). Before beginning his Ph.D. at Cornell, Steve studied psychology at the University of Michigan, working primarily with Ethan Kross.  When not in the lab, Steve enjoys spending time in the natural areas around Ithaca – hiking, running, biking, and kayaking. He also enjoys traveling, cooking, and watching his favorite team– Liverpool FC.
