About
I am a cognitive scientist who uses computational modeling and behavioral experimentation to investigate those complex forms of cognition that are uniquely human, and indeed make us human. My primary line of research is in mathematical and computational thinking, where my students and I investigate the cognitive mechanisms underlying our ability to understand abstract mathematical concepts (e.g., in geometry and topology) and to reason about computationally hard problems (e.g., the travelling salesperson problem). My lab also works on problem solving, with an increasing focus on bounded rationality and the interface between the internal cognitive system and the structure of the environment. Our research on language understanding is characterized by the development of computational models and the use of machine learning techniques.

About
In an era in which many people can live well into their eighties or nineties, articulating pathways to a quality life becomes more critical than ever before. At the broadest sense, I am interested in identifying the affective, cognitive, and sociocultural processes that shape long and meaningful lives. My research addresses three broad questions: (1) What factors contribute to meaningful lives? (2) How do individual life experiences, particularly those that are personally significant and challenging, shape the pursuit of meaning across the adult life span in diverse contexts? (3) What emotional and cognitive gains and losses might be involved in the process of striving for meaningfulness? I address these questions from a functional approach to autobiographical memory and consider how developmental changes in motivation across the adult life span may be at play.

Recruiting new PhD students for the Fall of 2024
My overarching research mission is to improve human flourishing by conducting meaningful and transformational research. While my primary training is in Industrial-Organizational Psychology, my research approach is not confined to studying the human condition at work. I take an interdisciplinary, person-centric, future-looking approach to examining the human experience across various contexts. Specifically, my work is organized around two central themes: Well-Being and Teams. For more information about my current research projects, please visit The Foundation Lab page

About
Cognitive control refers to the set of processes by which we direct our actions toward a specific goal. At the most basic level, control processes allow us to translate a presented stimulus into an appropriate motor action. However, these processes and representations quickly become more complex when trying to understand more involved behaviors such as learning peoples names or watching and understanding films. Research in our lab investigates both the cognitive and the neuroscientific aspects of the processes and representations required to carry out flexible behavior across a wide variety of domains.
