Faculty

Emilio Ferrer ([email protected]) is a Professor in the Department of Psychology at the University of California, Davis and a member of the Graduate Groups in Biostatistics, Education, and Human Development. His research interests include methods to analyze change and intra-individual variability, in particular latent change models and dynamical systems. His current research in this area involves techniques to model dyadic interactions as well as multivariate processes associated with reasoning, reading, and math achievement from childhood to adolescence. He is Editor-in-Chief of Multivariate Behavioral Research, and is co-editor of the books Longitudinal Multivariate Psychology and Statistical Methods for Modeling Human Dynamics. In 2013 he received the Early Career Research Award for contributions to multivariate psychology.

Samuel Aragones ([email protected]) is a 6th year Ph.D. student who is interested in social interactions in psychological processes. He obtained his bachelor's degree from UCLA in 2018 and has spent time working with scRNA-seq data to analyze and develop methods for differentiating cell types and cell populations at Eric Deeds’s Lab at UCLA. Apart from research, he enjoys rock climbing, boba, and games of any sort!
Suryadyuti Baral ([email protected]) is a 3rd year Ph.D. student in Quantitative Psychology. He grew up in Kolkata, India, and moved to the U.S. at the age of nineteen to attend UNC Chapel Hill. He graduated in 2024 with majors in Psychology and Statistics. His research in the DIPS lab centers on intensive longitudinal data analysis, focusing on developing methods for EEG data and investigating human cognition from an intraindividual perspective while accounting for interindividual variability. Outside of academics, Suryadyuti enjoys reading, watching movies, and playing chess. During his time at Davis, he has also grown fond of outdoor activities like biking and hiking.
Maia Southwick ([email protected]) is a 4th year Ph.D. student in Developmental Psychology at the University of California, Davis. She obtained her bachelor’s degrees in Psychology and Health, Society, and Policy from the University of Utah in 2021. Her research involves learning how to best represent intraindividual change and intraindividual variability in moral cognition across childhood and adolescence. Outside of research, she enjoys playing soccer, board gaming, and art!
Jenny Xu ([email protected]) is a 1st year Ph.D. student in Quantitative Psychology and Personality at the University of California, Davis. She graduated in 2026 with majors in Psychology and Statistics. Her research interests involve understanding how to optimally model the within-person dynamics among interrelated components of daily stress processes and quantify where individual differences in personality exert the strongest influence, using daily diary data. Outside of research, you can find Jenny at the ARC playing racquetball or baking red bean mochi bread in her apartment!
