Drew Abney

Associate Professor, Associate Head, Behavioral and Brain Sciences Program

My research focuses on how behaviors and social interactions impact developmental trajectories throughout infancy and into toddlerhood. Studies conducted in my lab use various techniques: from conducting controlled laboratory experiments to free-flowing toy play sessions to collecting daylong multimodal (e.g., vocalizations, body movements, etc.) behavioral data. I’m motivated to apply existing techniques from applied computational social science and dynamical systems theory and also develop new computational and analytic methods to understand the dynamics of development during infancy and early childhood.

*I am not recruiting graduate students during the 2025-26 application cycle*

Brinkley Sharpe

Graduate Student, Clinical Program

Brinkley received her MS in Psychology from the University of Georgia in 2022. Her doctoral research focuses on perceptions of and self-identification with general and maladaptive personality traits, including endorsement of a "cardinal" or dominant trait. Brinkley is an enthusiastic advocate of open science approaches as forces for transparency, collaboration, inclusion, and self-correction in science. Brinkley's primary clinical interests are the treatment of trauma-related pathology, psychodiagnostic assessment and case formulation, and working with LGBTQ+ clients. Brinkley likes cats, board games, jigsaw puzzles, pinball, and yoga.

Education:

Research Interests:

Broadly, I study antagonism, impulsivity, and other externalizing psychopathology. I am additionally interested the structure of psychopathology, ambulatory assessment methods, and dynamic models of personality.

 

Molly E. Hale

Graduate Alumni, Clinical Program
Education:

2020 - M.S. William & Mary (Experimental Psychology) 

2017 - B.A. University of Washington (Community Psychology)

Research Interests:

I am interested in understanding inter- and intra-personal factors that help to buffer the development of internalizing symptoms (i.e., anxious, depressive, somatic). Within a biopsychosocial framework, I examine the role of self-regulation, close interpersonal relationships with parents an friends, and synchrony using biobehavioral markers to identify how best to support youth's psychological development.
