Elliot Tucker-Drob is a Professor in the Department of Psychology and a Faculty Research Associate at the Population Research Center and the Center on Aging and Population Sciences at the University of Texas at Austin. Dr. Tucker-Drob received his PhD in Psychology from the University of Virginia, and has held fellowships at Harvard Medical School and the Max Planck Institute for Human Development. He co-founded and co-directs the Texas Twin Project.

Dr. Tucker-Drob’s research addresses the questions of how and why different people progress along different life trajectories. His research on infant, child, and adolescent development primarily focuses on how social and educational experiences combine with genetic variation to impact cognitive development, and mental health over time. His research on adult aging is primarily concerned with the predictors, patterns, and consequences of individual variation in aging-related cognitive declines and dementia. In support of this work, he constructs, evaluates, and applies a variety of statistical methods for cross-sectional, longitudinal, and genetic data.

Dr. Tucker-Drob is a fellow of the Association for Psychological Science (APS). From 2018 to 2020, he was a Jacobs Foundation Advanced Research Fellow. In 2019, Dr. Tucker-Drob received the Max Planck-Humboldt Medal. In 2017, he received Janet Taylor Spence Award for Transformative Contributions from APS. In 2015, he received the Fuller and Scott Award for Outstanding Scientific Accomplishments from the Behavior Genetics Association. Some of Dr. Tucker-Drob’s recent publications can be found in Psychological Bulletin, Nature Human Behaviour, Nature Genetics, Annual Review of Developmental Psychology, Psychological Science, and Developmental Psychology. His research is funded by the National Institutes of Health.

Laurel Raffington (Postdoctoral Research Fellow)

Dr. Laurel Raffington completed a BSc in Experimental Psychology at the University of Bristol and a MSc in Social, Cognitive and Affective Neuroscience at the Freie Universität Berlin. During this time, she explored a range of psychology research topics by working as a research assistant or intern in the labs of Dr. Bruce Hood, Dr. Marcus Munafò, Dr. Karen Adolph, Dr. Bernhard Fink, Dr. Kimberly Noble, Dr. Hauke Heekeren, and Dr. Ben Godde. Her PhD research at the Max Planck Institute for Human Development was funded by the Berlin School of Mind and Brain in Germany. Under the supervision of Dr. Yee Lee Shing, Dr. Christine Heim, and Dr. Ulman Lindenberger, she investigated longitudinal associations of family income and children’s reading and mathematical development. Dr. Raffington’s PhD research also examined the potential role of chronic stress and cortisol secretion in mediating socioeconomic disparities in children’s cognitive development within the Jacobs Study, which she co-founded. She also co-founded a video project that discusses racism in Germany. After her PhD, Dr. Raffington continued working within the Jacobs Study, funded by the Jacobs Foundation, as a postdoctoral researcher at the Max Planck Institute for Human Development.

Dr. Raffington joined the Texas Twin Project as a postdoctoral research fellow funded by the German Research Association in February 2019 under the mentorship of Dr. Elliot Tucker-Drob and Dr. Paige Harden. Her primary research interest explores how genetic and environmental interactions contribute to individual differences in neuroendocrine function and behaviors often found to correlate with socioeconomic status. To this end she utilizes behavior genetic and epigenetic methods that she hopes may inform intervention research.

He was conferred his Ph.D. summa cum laude in the Fall of 2019. Dr. de la Fuente’s current research continues his track record of applying sophisticated multivariate statistics to study the epdemiology of cognitive aging and health, and expanding his expertise to include advanced method in statstical genomics and genetic epidemiology.

Kelseanna Hollis-Hansen (Postdoctoral Research Fellow)

Dr. Kelseanna Hollis-Hansen is an NHLBI T32 postdoctoral fellow in the Dell Medical School and the Steve Hicks School of Social Work. Dr. Hollis-Hansen’s focus is on designing and analyzing food retail interventions that aim to improve diet and increase food equity in under resourced communities. In addition, she is using data from the Texas Twins Project to identify what elements of the built and social environment are associated with biological mechanisms (e.g. DNA methylation, stress hormones) that may influence physical and cognitive health outcomes.

Dr. Hollis-Hansen finished both of her graduate degrees at the University at Buffalo, State University of New York. While completing her master of public health (MPH), she worked with Dr. Youfa Wang to analyze and expand NASA’s Mission X: Train Like an Astronaut school-based childhood obesity prevention program to an online platform. Throughout her PhD, Dr. Hollis-Hansen worked under Dr. Leonard Epstein in the Division of Behavioral Medicine with a focus on translating reinforcement pathology and behavioral economic theory into a grocery shopping intervention for parents interested in buying healthier food for their families.

Lucy King (Postdoctoral Research Fellow)

Dr. Lucy King completed her PhD in Psychology at Stanford University where she worked under the supervision of Dr. Ian Gotlib and collaborated with Dr. Kathryn Humphreys to design, fund, and manage the Brain and Behavior Infant Experiences (BABIES) project, a longitudinal study of the impact of the perinatal environment on infant neurodevelopment. For her dissertation, Dr. King investigated how infants’ everyday interactions with their caregivers may affect how their brains function and whether they develop early signs of psychopathology. In addition, she created a novel assessment of early adverse experiences within the context of the caregiver–child relationship (see Her graduate research received funding from the National Science Foundation, the American Psychological Foundation, and the Stanford Institute for Research in the Social Sciences.

Dr. King joined the Lifespan Development Lab in Spring 2021 after receiving an F32 Ruth L. Kirschstein National Research Service Award from the National Institute for Child Health and Human Development. During her fellowship, Dr. King is working under the supervision of Dr. Elliot Tucker-Drob and Dr. Charles Zeanah (Tulane University) to examine environmental and genetic contributions to young children’s trajectories of psychological development. She will specifically consider how early caregiving experiences combine with genetics to affect risk for cognitive and socioemotional difficulties among orphaned children raised in institutions and foster care as well as children raised in their families of origin.

Ted Schwaba (Postdoctoral Research Fellow)

Dr. Ted Schwaba completed his BS Summa Cum Laude in Psychology and Communications at Northwestern University in 2014, where he worked with Dr. Anne Marie Piper studying human-computer interactions in older adulthood and Dr. Dan Mroczek studying personality assessment in emergency departments. In 2021, he completed his PhD in Psychology at the University of California Davis, working with Dr. Wiebke Bleidorn. During these years, he focused his research interest on using modern statistical techniques and large datasets to understand lifespan personality and psychopathology development. How do people change across the lifespan, and what role do life events (like retirement) and experiences (like lead exposure) play in this change?

As a postdoctoral research fellow in the Lifespan Development Lab, Dr. Schwaba continues to address questions about the origins of personality and psychopathology, now at the genetic level. In Dr. Schwaba’s current line of research, he uses genomic Structural Equation Modeling to better understand sex differences in the genetic structure of psychopathology.
