My research involves the development and application of mathematical, computational, and statistical techniques to theoretical and methodological problems within the areas of social and biological network analysis, mathematical sociology, quantitative methodology, and human judgment and decision making. Currently, my work focuses on: the structure of spatially embedded large-scale interpersonal networks; theory and applications of discrete exponential family models for cross-sectional and dynamic relational data; Bayesian methods for network inference, model integration, and properties of biological systems; relational event models; network sampling; and methods for the analysis of time-resolved activity data. I am also interested in social phenomena related to emergency situations, and am involved in research which seeks to combine social science and information technology to improve group and organizational responses to disasters and other adverse events. My teaching interests include social networks, the sociology of decision making, quantitative methodology, and computational methods.

I am currently supervising four Ph.D students in the Department of Sociology, one in EECS, one in Computer Science, and one in ChaMP: Sean Fitzhugh, Ben Gibson, Emma Smith, Xuhong Zhang, Yue Yu, Eric Casavant, and Francis Lee. Ph.D students I have graduated (yes, it does eventually happen!) so far include Christin Hilgeman, Miruna Petrescu-Prahova, Ryan Acton, Chris Marcum, Lorien Jasny, Zack Almquist, and Emma Spiro.
Other doctoral students with whom I have worked fairly extensively include Minas Gjoka (Networked Systems Program), Gabriel Lawson and Fabio Leite (of the Institute for Mathematical Behavioral Sciences), Christine Bevc (Department of Sociology, University of Colorado), Nicole Beckage (Cognitive Sciences), Ragupathyraj Valluvan (EECS), and Rupa Jose (Psychology and Social Behavior), as well as Remy Cross, Ben Lind, Kimberly Marx, Nicole Pierski, Leah Reich, and Nolan Phillips (Department of Sociology). Look for great deeds from all of these fine researchers in the years to come....
