I'm a researcher with a multidisciplinary background in computer, data, and social sciences, business, and philosophy.
My current research foci are privacy engineering and software assurance.
Current Research Roles
Digital Life Initiative
I'm a Research Fellow at Cornell Tech's
Digital Life Initiative, where I research applications of contextual integrity in computer science and information economics.
I'm also a data scientist at Ion Channel, a software supply chain intelligence startup. Check out this presentation of some of our cybersecurity work:
Sebastian Benthall. Context, Causality, and Information Flow: Implications for Privacy Engineering, Security, and Data Economics. Ph.D. dissertation. Advisors: John Chuang and Deirdre Mulligan. University of California, Berkeley. 2018. (eScholarship) (slideshare)
Abstract:The creators of technical infrastructure are under social and legal pressure to comply with expectations that can be difficult to translate into computational and business logics. This dissertation bridges this gap through three projects that focus on privacy engineering, information security, and data economics, respectively. These projects culminate in a new formal method for evaluating the strategic and tactical value of data: data games. This method relies on a core theoretical contribution building on the work of Shannon, Dretske, Pearl, Koller, and Nissenbaum: a definition of situated information flow as causal flow in the context of other causal relations and strategic choices.

My research involves writing a lot of software.
BigBang is a toolkit for the scientific analysis of open collaborative communities.

GeoNode, an open source geospatial data management system. I worked on this at OpenGeo, which is now called Boundless. There is still a great team working on it and deploying it as a product.
In Fall 2013 I co-instructed a course on Open Collaboration and Peer Production with Thomas Maillart. It was aimed primarily at Masters students at the School of Information, fulfilling a Management requirement. My instruction was based mostly on my professional experience working in and managing open source software communities.
