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. She has published over 30 peer-reviewed journal articles, book chapters, and conference proceedings in psychology and engineering outlets and has received multiple national awards and fellowships, including the National Science Foundation Graduate Research Fellowship, the American Psychological Association Dissertation Award, the American Psychological Association of Graduate Students Basic Psychological Science Grant, and the American Psychological Association of Graduate Students Junior Scientist Fellowship. She holds two pending patents for inventions relating to mobile health machine learning applications for couple and family therapy. Her work has been featured in various press outlets, including BBC, NBC, Yahoo News, CNET, and TechCrunch. Visit our research page to learn more about Dr. Timmons' work.

Dr. Timmons is also the founder and CEO of Colliga, a startup company funded through an NIMH STTR grant that uses technology, AI, and pervasive computing to build research tools for promoting health and wellbeing.

Jacqueline Duong, M.A.


M.A., Psychology, San Diego State
B.A., Sociology, University of California, Berkeley

Jacqueline Duong is a second-year doctoral student. She obtained an M.A. in Psychology from San Diego State University and a B.A. in Sociology from the University of California, Berkeley. She is broadly interested in examining how children and families, especially those from traditionally under-served and under-represented backgrounds, can positively respond to stress, trauma, and adversity. She is also interested in exploring the clinical use of mobile health tools to examine the impact of parental psychopathology on child wellbeing.

Sierra Walters, B.S.



B.S., Psychology and Kinesiology & Health Sciences, College of William & Mary

Sierra Walters is a first-year doctoral student. She received her B.S. in Psychology and Kinesiology & Health Sciences at the College of William & Mary. At William & Mary, she conducted research with children of incarcerated individuals, fostering an interest in working populations exposed to adversity. While pursuing her graduate studies, she is interested in exploring how children and families show resilience in response to stress and trauma, especially the impact of parental relationships on a child’s emotional response to stress. 

Kayla Carta, B.S.



B.S., Chemistry, Keene State College

Kayla Carta is a first-year doctoral student. She obtained her B.S. in Chemistry at Keene State College. After graduating, Kayla pursued clinical research and studied cognitive function in patients with schizophrenia at Johns Hopkins School of Medicine. More recently, she worked for the Center for Neuroscience in Women’s Health and the Pediatric Mood Disorders Program at Stanford University where she studied emotional regulation in adolescents at-risk for mood disorders. Kayla is interested in studying the effects of parental stress on children’s moods and using technological tools to promote supportive family environments to prevent the onset of psychiatric disorders.
