Dr. Adela Timmons is the director of the Technological Interventions for Ecological Systems (TIES) Lab. Dr. Timmons’ research examines how childhood stress, trauma, and adversity become biologically embedded and impact stress reactivity and emotion regulation capacity in the context of interpersonal relationships. She is particularly interested in coregulation processes, or how people in interpersonal relationships share in their moment-to-moment physiological and emotional states. To conduct her research, she uses both laboratory-based and ambulatory assessment methods to capture relationship dynamics as they naturalistically unfold. She is also interested in the development of new technologies and measures for automatically and passively capturing and quantifying interpersonal functioning in real-life contexts. She is currently developing just-in-time adaptive mobile health interventions using machine learning and wearables, with the goal of improving mental health outcomes for children, couples, and families. Her research is interdisciplinary, spanning clinical science, quantitative psychology, and engineering domains.
Dr. Timmons received a combined Ph.D. in Clinical Science and Quantitative Psychology from the University of Southern California in 2018 and completed her predoctoral internship in Clinical Psychology at the University of California, San Francisco in 2018. She obtained a combined M.A. in Clinical Science and Quantitative Psychology from the University of Southern California in 2013 and graduated summa cum laude with a B.A. in Psychology and a minor in Behavioral Sciences Research Methodology from the University of Kansas in 2011. She joined the faculty at Florida International University as an Assistant Professor of Clinical Science and Quantitative Psychology in 2018. In 2022, she joined the faculty of the University of Texas at Austin and teaches an undergraduate course on Childhood Trauma and Adversity.
