Student Supervision

I welcome opportunities to supervise undergraduate and graduate students, post-doctoral fellows, and other training fellows on projects that focus on the current research priorities of the Citizen Lab, which are listed below.

Due to the volume of requests I receive, I cannot evaluate proposals or discuss research topics with individual students until they are accepted into one of the programs / opportunities outlined below. Please read the following carefully before reaching out to me.

Graduate Students (Masters and Doctoral)

I primarily supervise graduate students interested in some aspect of information and communication technologies who are enrolled in the following programs:

Given the unorthodox nature of my research, I also co-supervise and serve on the committees of doctoral students outside of political science, including computer science, law, and engineering.

Undergraduate Students

On occasion, no more than once a semester, I supervise undergraduate senior theses and independent reading courses.

The Citizen Lab does not offer volunteer positions for undergraduate students, but occasionally hires undergraduate research assistant positions which are advertised on the Citizen Lab website.

Post-doctoral Fellows

Post-doctoral fellows are expected to pursue research interests that fall within one of the Citizen Lab’s main research priorities (listed at the top of the page), as well as to provide leadership and guidance to junior scholars and researchers.

Post-doctoral opportunities are posted on the Citizen Lab website as they come available. I also welcome requests to host and supervise post-doctoral fellows from computer science, law, engineering sciences, and political science who have secured their own funds (e.g., a SSHRC or NSERC postdoctoral fellowship). The Faculty of Arts and Sciences at the University of Toronto also has an advertised post doctoral fellowship program.

Other Fellowships

Interested students and others should check the Citizen Lab website for fellowship opportunities and application deadlines.

Main Thematic Areas

Comparative Analysis of National-Level Information Controls (Network Monitoring)

This area is primarily about information controls at a national level — e.g., Internet censorship and surveillance. Citizen Lab work includes developing new tools and methods for network measurement, analyzing Internet filtering systems, and correlating network interference with political events (e.g., elections, protests, conflicts, etc). We were part of the OpenNet Initiative for over ten years, and as part of that research undertook comparative analyses of information controls in more than 70 countries. A byproduct of this research is the use of network measurement and scanning techniques to fingerprint the vendors of commercial surveillance, content filtering, deep-packet inspection, and other products and services. We also evaluate laws, policies, and norms related to the topics outlined above, on national and comparative bases. Students who are interested in understanding practices, norms, laws, and technologies around information controls at a national level would find a lot to build upon in this area. Citizen Lab works with a network of researchers in the global South, which means that we have good partnerships with groups in those regions and good insight into the situations in the developing world. I am very interested in students working in comparative developing politics who are interested in better understanding practices and policies around cyber security in the global South, in failed and fragile states, and among authoritarian regimes or countries transitioning in and out of democracy.

Targeted espionage against civil society

This research area focuses on investigating politically motivated targeted malware and other digital attack campaigns against civil society. This area of research includes reverse engineering malware, mapping attack infrastructure, tracking malware development, and linking contextual information to technical data through investigative research techniques and structured focused interviews. We are interested in better understanding the threat environment facing civil society organizations in the digital arena, especially as their adversaries become better equipped with surveillance and spyware tools. This area can involve exceptionally rigorous technical work (e.g., reverse engineering malware and mapping command and control infrastructure) but can also lend itself well to research that examines the political context around such attacks, the legal and regulatory environment around the control of surveillance technologies, structured focused interviews around specific targeted communities and their responses or defences to attacks, risk mitigation, and evidence of psycho-social harms.

Privacy and security of mobile apps and social media

Projects in this area include uncovering censorship and surveillance in popular applications and social media platforms (e.g, chat apps, microblogs, etc), and evaluating the privacy and security of popular consumer apps (e.g., browsers, fitness trackers, etc). We are particularly interested in widely used apps and platforms that are understudied by security researchers. The goal of this work is to help users make more informed decision about the technologies they use and better understand the way threat actors might exploit privacy and security flaws to track high risk users. Students who are interested in researching how Internet intermediaries (e.g., mobile carriers, applications) affect information controls would find a lot to work with in this area. This area also lends itself well to national comparative analyses of Internet censorship and surveillance in the mobile arena.

Corporate and public transparency

Projects in this area include developing software platforms for empowering citizens to exercise their rights to data protection and access requests, and analyzing the systems, policies, and practices of telecommunication and Internet companies as it pertains to the handling and sharing of customer data. We are especially interested in tracking state SIGINT practices, in Canada and abroad, as revealed by the Snowden disclosures and other sources of information. I am presently supervising PhD students in political science who are exploring the impact of the Snowden disclosures on SIGINT practices, and the norms governing intelligence sharing among the FVEYs. We are also presently developing out and expanding research on the Access My Info project to several jurisdictions outside North America, offering the first opportunity to analyze primary data on corporate data handling and sharing practices that arises from user requests.

Disinformation and Digital Technologies

Disinformation and digital technologies is a relatively new topic of interest for us at the Citizen Lab. We typically undertake research on disinformation that intersects with one of our other main thematic areas of interest.
