Sy-Miin Chow is Professor of Human Development and Family Studies at the Pennsylvania State University and the Principal Investigator of the Emotions and Dynamic Systems Lab. Dr. Chow’s research focuses on the development and adaptation of modeling and analysis tools that are suited to evaluating linear and nonlinear dynamical systems models, including longitudinal structural equation models and state-space modeling techniques. Her current work involves using Kalman filter approaches and dynamical systems models to represent the dynamics of emotion regulation. Her longer term aim is to develop a broader repertoire of data-driven tools tailored toward analyzing the kinds of longitudinal data typically available in the social and behavioral sciences.

I am currently a doctoral candidate in human development and family studies. I received a Bachelor of Science degree in mathematics and applied mathematics from Zhejiang University in China, a Master of Science degree in human development and family studies, and a Master of Science degree in statistics, both from Penn State. My research interests lie in dynamic systems modeling and time series analysis, as well as the application of these methods to studying dynamic processes in individuals and groups. Specifically, I am interested in 1) frequentist and Bayesian estimation techniques for fitting linear and nonlinear dynamic systems models; 2) machine learning/data mining and other nonparametric techniques for exploring inter-relations among high-dimensional dynamic data; and 3) applications of dynamic system models to real-time process data (e.g., in emotion regulation, communication, and collaboration). During my graduate career, I have worked with Dr. Sy-Miin Chow on developing statistical and computational methodologies to study human processes (e.g., use of likelihood ratio tests in initial condition examination of the autoregressive latent trajectory model, and estimation techniques for regime-switching continuous-time models). My current projects include the development and improvement of the dynr package for multivariate time series analysis in R and applications of dynamic models and data mining techniques to dyadic co-regulation and emotion regulation. Beyond research, I have worked as a student consultant at the Statistical Consulting Center at Penn State, helping university-wide students with their data collection and analysis. I have also been involved in teaching online and offline, undergraduate and graduate courses at Penn State.

I am a fourth year graduate student working with Dr. Sy-Miin Chow. My research interest lies in the statistical models and methods to be used in capturing individual and dyadic dynamics in longitudinal data. I also wish to contribute to the development and application of models/methods that can address different kinds of data in developmental research. I received my B.A. in psychology and mathematics from Smith College in Massachusetts.

I am a PhD student working under the mentorship of Dr. Sy-Miin Chow.  I am also pursuing a concurrent graduate degree in applied statistics.  My research interest lies broadly in applying statistical methods to the study of child development processes in the context of family systems.  In particular, I am interested in developing and applying dynamic systems modeling techniques to study intra-individual change as well as inter-individual differences in the emergence and development of child regulatory and mother-child co-regulatory processes, and how contextual factors, such as parenting and household environment, would influence the development of these processes.  I received a Master of Education degree at Harvard Graduate School of Education, where I mainly worked on child-parent interaction, child language and cognition development, and technology-facilitated learning.

Hi! I am currently a fourth year PhD student in Department of Computer Science and Engineering, Penn State University, working under the supervision of Prof. Wang-Chien Lee. My primary research is in the area of social network analysis and data mining. Some of my work has been published in ACM KDD, ACM CIKM, IEEE ICDCS, and IEEE GLOBECOM.

I am generally interested in modeling psychological growth, especially within the substantive areas of academic achievement. Accordingly, I have been studying quantitative methods to figure out the way of capturing dramatic changes in longitudinal data. I also have a huge interest of big data analysis and recently have participated in analyzing social media that people post about their medical symptom.
