Social Science Topics
I am broadly interested in understanding the factors that contribute to human interpersonal behavior, including internal factors (e.g., emotion, personality, and psychopathology) and external factors (e.g., context, culture, and group processes). Much of my work has focused on the analysis of nonverbal behavior in depression. However, I have also done work on personality disorders, culture, and gender.
Computer Science Topics
I am broadly interested in developing and validating computational tools to facilitate research in the social sciences. Much of my work has been related to the use of computer vision and machine learning to automate the analysis of human facial behavior. However, I have also developed software tools for collecting observational measurements and conducting statistical analyses.
Data Science Topics
I am broadly interested in applying and disseminating methods for collecting, organizing, and analyzing research data, including software engineering, statistical analysis, and machine learning. Much of my work has been related to the use of multilevel modeling and reliability analysis. However, I have also done work on structural equation modeling, machine learning, and contemporary validity theory.
