Reseach interests

An important part of his research is centred around modelling measurement error in the framework of generalized latent variables (i.e., Structural Equation Modelling, Latent Class and Item Response Theory) with a particular interest in applying these to longitudinal data.

Oshan, Taylor M.

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 statisticsgeographic 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

Sivan-Sevilla, Ido

Assistant Professor

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.
