Modeling Interventions on Social Networks

Wednesday, January 20, 2021

Time: 11:00 a.m.

Speaker: Tracy M. Sweet, Associate Professor, Measurement, Statistics & Evaluation, Department of Human Development & Quantitative Methodology, University of Maryland

Abstract: There are some interventions aimed at changing the ways in which individuals interact, and social networks are particularly useful for quantifying these changes. For many of these interventions, the ultimate goal is to change some individual outcome of interest, and social networks act as a natural mediator. For example, in an educational intervention the goal is to change the behavior of students but changes in peer networks are actually the mechanism through which the intervention is effective. In this talk, I will introduce social network models, present a framework modeling social networks as outcomes and mediators and present some recently developed models that embed networks into mediation models.

 Data Science in Support of Management of SARS-CoV-2 Community Spread for a Large Metropolitan Area

Wednesday, January 27, 2021

Time: 11:00 a.m.

Speaker:  Katherine Bennett Ensor, Noah G. Harding Professor of Statistics, Rice University

Abstract: City and county governments in the greater Houston area have a long history of partnering with research universities in the region to address local challenges. I bring forward several data and statistics intensive projects that improve understanding and management of Covid-19 prevalence in the region. The projects include a regional and national registry, a statistically designed seroprevalence study, carefully curated case count information, and a large temporal and spatial study of viral shedding found in wastewater. I will also discuss the challenges of bringing state-of-the-art science to bear on real-time public health issues.
