I am broadly interested in characterizing spatial patterns and processes through the use of quantitative geographic methods, which typically falls under the banners of spatial analysis and spatial statistics, geographic information science, and the emerging discipline of spatial data science. My work typically involves modeling human processes within urban environments and therefore also intersects with the disciplines of computational social science, and urban informatics. Overall, my research has targeted the development of multivariate spatial statistics and how they can be used to capture how relationships change by spatial and temporal contexts. This includes issues of theory, interpretation, scalability, and integration of traditional geographic models with novel “big” datasets, as well as applications in public health, crime, urban mobility, and transportation systems. I also participate in open source software development and building cyber-infrastructure to support my research and teaching and facilitate the replicability and reproducibility of the geographical science

Other projects include developing privacy-sensitive search for email collections; analyzing ethical cultures in computer security research; and building tools to facilitate ethics discussions in mobile application development.
Dr. Sivan-Sevilla is a comparative social scientist & technologist who measures and theorizes about the way our information society is governed. He investigates digital risk governance over a broad range of cybersecurity, privacy, discrimination, and manipulation problems, looking at governance structures set by private industries, elected officials, and bureaucrats, across sectors and political systems. Methodologically, Ido utilizes his technological background to empirically investigate industries (e.g. AdTech) and threat actors (e.g. hackers & trackers), shedding light on bottom-up governance arrangements. He complements such understanding with text analysis, interviews, and surveys to uncover and explain the operation of top-down policy regimes in this space, by private and public actors (e.g. cyber insurers, certifiers, policymakers, and regulators).
His work has been published or presented in The Journal of Public Policy, Journal of Risk Research, Policy & Internet, Georgetown Journal of International Affairs, NATO’s International Conference on Cyber Conflict (CyCon), and FTC’s Privacy Conference, among other venues.
Dr Stapleton is interested in the analysis of administrative data and survey data obtained under complex sampling designs, multilevel latent variable models, tests of mediation within a multilevel framework
Kathleen Stewart is Professor in the Department of Geographical Sciences and Director of the Center for Geospatial Information Science. She works in the area of geographic information science with a particular focus on geospatial dynamics. She is interested in mobility and spatial access, often in a big geospatial data context and using approaches that lie in the expanding field of spatial data science. She investigates movement and mobility for a number of different application domains, for example, health and transportation where movement patterns or behaviors and spatial access are key topics. She is also interested in modeling geospatial semantics including geospatial ontologies and their role for location-based applications, and spatiotemporal information retrieval, i.e., computational methods for automatically acquiring meaningful space-time information from text sources. She teaches in the areas of spatiotemporal data modeling, geographic database design, geovisualization and cartography, and fundamentals of geographic information science. At the University of Maryland, Dr. Stewart is a member of the Program in Oncology at the University of Maryland Marlene and Stewart Greenebaum Comprehensive Cancer Center and also collaborates with researchers at the Center for Vaccine Development and Global Health, the Center for Substance Abuse Research, the Maryland Transportation Institute, the School of Public Health, and the Social Data Science Center among others. Her research is supported in part by grants from the National Institutes of Health, the National Science Foundation, the Federal Highway Administration, and Maryland Department of Natural Resources among other organizations.
Tracy Sweet is an Associate Professor in the Measurement, Statistics and Evaluation program in the Department of Human Development and Quantitative Methodology.

I am a Professor of Political Science and Empirical Democracy Research in the School of Social Sciences at the University of Mannheim. I am also affiliated with the Institute of Empirical-Analytical Research (InFER) and the Research Institute Social Cohesion (RISC) at Goethe University Frankfurt. Previously, I held positions at the Graduate School of Economics and Social Sciences (GESS) in Mannheim, Goethe University Frankfurt, the University of Essex, the Mannheim Centre for European Social Research (MZES) as well as the universities of Berne and Konstanz. I study the socio-structural and psycho-cultural requisites of democracy with a strong focus on problems of social cohesion and conflict. My current research involves the politics of free speech and censorship, citizens’ preferences for migration policy, the rural-urban political divide and the civic consequences of wartime sexual violence. I also have a keen interest in quantitative political methodology, including Bayesian methods, data visualization and survey experiments. My work has been published in British Journal of Political Science, Comparative Political Studies, Political Analysis, and Sociological Methods & Research, among others.
