Lab Director and Principal Investigator (PI)

I am interested in the development of explanatory models of personality traits as reflections of psychological and biological parameters within an evolved adaptive system. Personality is conceived broadly as encompassing all reasonably stable individual differences in emotion, motivation, cognition, and behavior. My Cybernetic Big Five Theory attempts to provide a unifying theory for personality psychology and personality neuroscience, as well as psychopathology and well-being.

Aisha Udochi

Aisha Udochi

[email protected]

Aisha's research interests focus on understanding identity and personality traits related to prosocial behavior. Her goal is to identify how relatively straightforward descriptions of personality are linked to more complex psychological processes and brain function. Additionally, she is interested in understanding how personality traits and their neural underpinnings relate to a person's perceived sense of self.


Tyler Sassenberg

Tyler is interested in understanding the neurobiological, affective, and behavioral mechanisms that influence different personality traits. His particular research interests include exploring the nature of traits Extraversion and Openness/Intellect through different psychometric and neuroimaging methods.



Edward Chou

Edward Chou

Edward is a generalist who has found refuge in the field of personality psychology. His research interests include applied psychometrics, the structure and processes of traits beyond the Big Five (e.g., Aspects, Metatraits), as well as idiographic approaches to personality (e.g., psychotherapy, life stories).



Matthew Rogers

Matt Rogers

Matt is interested in studying the neurobiological mechanisms underlying different personality traits. In particular, he is interested in traits normally associated with autism spectrum disorder and how they might be incorporated into a cybernetic theory of personality. His other interests include modeling the neural circuitry of the hippocampus and simulating agents as generative models within a Markov decision process (MDP) framework.

Allison Dai

Allison Dai

Allison's research interests focus on 1) examining the neurobehavioral systems underlying normal and maladaptive personality traits, 2) understanding the interplay between personality traits and psychopathology as well as environmental factors that influence personality-psychopathology dynamics. Additionally, she is interested in developing instruments for assessing psychopathology within a dimensional and cybernetic framework.
