I am an Associate Professor in the Department of Public Law and Governance at Tilburg Law School. I received my PhD (cum laude) from Tilburg Law School in September 2021 for my doctoral thesis entitled: 'A Kaleidoscope of Meaning Fragments: Understanding the Rule of Law's Paradoxes in International Development'

Prior to that I completed an M.St. in Socio-Legal Research at Oxford University, an LL.M. in Comparative Law at McGill Law School, a B.A. in Common Law at the University of Ottawa, an M.A. in Russian and East European Studies at the University of Toronto, and a B.A. in History & Political Science, also at the University of Toronto. 


 I am a Canadian lawyer and member of the Bar of Ontario. Between 2010 and 2012, I worked as a civil litigator in Toronto before returning to academia in 2012. Prior to that, between 2008 and 2010, I worked in Afghanistan on international development projects and as a legal consultant. It was upon this experiential base that I later developed my doctoral thesis a decade later. Since 2020 I have been a member of the 'Constitutionalizing in the Anthropocene' Sector Plan research project at Tilburg University and have been transitioning my research in this direction ever since. I also conduct research for the NWO-funded 'Reducing Greenhouse Gas Emissions from Agriculture: the Role of Emissions Trading' project. My research interests are broad, but often focus around the Anthropocene and climate change law, law and development, systems, interdisciplinarity, and qualitative empirical methods.


I currently teach in the first year of the Global Law bachelor's program. I co-teach Introduction to Global Law I in the first semester, and I am the course coordinator for Introduction to Global Law II in the second semester. I also teach in the Research Design and Methods for Postnational Lawyers (RePL) course and supervise masters theses for the LLM program in International Law and Global Governance. I also occasionally supervise bachelor theses for Tilburg University's Liberal Arts & Science Program.

As of December 2022, I was appointed the Head of Teaching for the Department of Public Law and Governance.
