In my PhD, I evaluated the EU’s International Investment Policy. I was a visiting Research Fellow at the Centre for the Law of EU External Relations (CLEER) at the T.M.C Asser Institute in the Hague and at the Max Planck Institute for Comparative Public Law and International Law in Heidelberg. I completed traineeship at the Chambers of Judge Christopher Vajda at the Court of Justice of the European Union and participated in the International Academy for Arbitration Law in Paris. I was a Research Assistant at the Investment Treaty Forum of the British Institute of International and Comparative Law.

I am currently the Senior Tutor at the Leicester Law School and a Fellow of the Higher Education Academy. Together with Lauren Shellard, I run the Law Peer Support Network. 

I have been a lecturer at the Leicester Law School since September 2017. Prior to my appointment as a lecturer, I worked in the Department as a Graduate Teaching Assistant. I graduated with BA (Hons) in Economics and Law and LLM in International Commercial Law (with Felicidad Martinez Purrinos Memorial Prize), both from the University of Leicester. I completed my PhD in 2018 with no corrections.


My main research interests are in fields of EU external relations law, EU constitutional law, international economic law and international investment law. My current projects concern the interaction between the EU legal order and international investment law, as well as the rule of law crisis in Europe.
