Matthew Nassar

Ph.D., Neuroscience, 2012
University of Pennsylvania | Philadelphia, Pennsylvania
Research Interests

I am interested in how neuromodulators might allow cortical circuitry to facilitate different behavioral regimes in order to allow optimization across a broad array of environmental contexts. For example, one branch of my research investigates the role of catecholamines in adjusting the relative contributions of internal and external sources of information to improve learning and perception in dynamic environments. My research relies on detailed quantification of human behavior in cognitive and perceptual tasks, computational modeling, and indirect measurements of neural function such as fMRI, EEG, and pupillometry.

Andrew Westbrook

PhD Washington University
St. Louis 2016
MA Washington University
St. Louis 2012
MS
University of North Carolina
Chapel Hill 2006
BS University of Illinois
Urbana-Champaign 2003

Research Interests

Andrew is interested in decision-making about cognitive effort. In particular, he’s interested in what role dopamine plays in learning costs and benefits and also translating instantaneous motivation into promoting or undermining cognitive control. When he’s not investing cognitive effort in his work, he spends his time rock climbing, getting riled up about politics, and reading the news obsessively.


Graduate Students

 

Louis Gularte

MA, Philosophy, 2013
Northern Illinois University | DeKalb, Illinois

BA, Philosophy, 2008
BA, Psychology, 2008
University of Notre Dame | Notre Dame, Indiana

Research Interests

My philosophy dissertation work is on the nature of (dis)value and morality and how that interacts with the nature of suffering; my main interests are in metaethics and the philosophy of language and mind. In cognitive science, my hope is to get as clear as possible on the nature of suffering by looking at the interactions between negative affect on the one hand and reward learning and decision-making more broadly on the other.

Harrison Ritz

MSc. – Psychology, University of Western Ontario | London, ON, CA
BSc. – Psychology | Queen’s University, ON CA

Research Interests:
My undergraduate and masters’ theses focused on the neural correlates of attentional control during auditory and speech perception. My current research interests are broadly about characterizing neural systems that dynamically control decision-making in noisy, unstable environments. In my free time, I like watching films, distance running, batch cooking, and creating or listening to music.

Andrea Mueller

B.S. Psychology & B.S. Evolutionary Anthropology 2016
University of New Mexico | Albuquerque, NM
Research Interests

I am interested in how people process and express emotion, specifically what leads to internal versus external expression. My current work explores the relationship between inherent action-outcome biases and emotional approach-avoidance biases.
