Postdoctoral Fellow

Dr. Kaitlyn Campbell is a postdoctoral fellow in the lab. She graduated from Temple University in 2025 with a doctorate degree in psychology with a quantitative methods concentration. She graduated from the University of Idaho in 2019 with a B.S. in psychology & a pre-health studies minor. Her interests include multisensory integration and the intersection of executive functioning development, attention, and social interaction utilizing EEG methodology. Her dissertation focused on exploring at-home longitudinal fine motor development in infancy using kinematic analysis in relation to a neural measure of how the fingers are represented in the brain. Outside of the lab, Kaitlyn likes to make pottery, crochet amigurumi, and spend time with her pets.
Graduate Student

Allison Langer is a fourth-year Ph.D. student in the Developmental Psychology Program. She graduated from the University of Pennsylvania in 2017 with a B.A. in the Biological Basis of Behavior and a minor in psychology. She is interested in the link between motor development and social development, particularly in individuals with neurodevelopmental disorders. Outside of the lab, Allison loves to cook, attend dance classes, and run on local trails in Philly.

Collaborators

Dr. Valentina Parma is a collaborator on our longitudinal kinematics study of infant fingers. She was a Research Assistant Professor at Temple University, however, she recently started working at the Monell Center for the Chemical Senses in Philadelphia. She received her Ph.D. in Experimental Psychology in 2012 from the University of Padova, Italy. Her research focuses on understanding how unconscious stimuli, in particular odors, affect how humans control action and cognition both at the behavioral and the neural level.

Dr. Georgios Pavlakos is a collaborator on our longitudinal kinematics study of infant fingers. He is an assistant professor at the University of Texas at Austin in the Computer Science department. He received his Ph.D. in Computer and Information Science from the University of Pennsylvania in 2020.

Ab.Acus is a company based in Milan, Italy. They focus on research and development in digital systems, transparent technologies, localization devices, self-tracking systems, and simulation and modelization techniques. They collaborate with us on our current study on how infants learn to reach and grasp objects. They developed the TrHandy phone application we implement in that study, among other behind-the-scenes programs.
