F Deni Mantzari

Deni Mantzari joined the Faculty in September 2009 as a PhD Candidate working under the supervision of Dr. Ioannis Lianos and Professor Richard Rawlings. Deni’s research focuses on Judicial Review of Economic Evidence in the wake of Energy and Telecoms liberalization. The main research question of her thesis is whether in the age of growing economic expertise in these sectors, generalist courts are well equipped to adequately review independent regulatory agencies’ decisions. This nagging issue is explored in a number of jurisdictions, namely the EU, the US, and the UK. She is the recipient of the UK Arts and Humanities Research Council (AHRC) Scholarship for 2009-2012.

Deni holds an LL.B from National University of Athens (merit) and an LL.M in European Union Law (distinction) from UCL. In 2010, Deni was awarded an AHRC Study Visit Fund and spent a semester at UC Berkeley Boalt Hall School of Law conducting research on US Administrative Law, Antitrust, and Telecommunications Law as well in the field of political science under the supervision of Professor Martin Shapiro. She also attended the Law and Economics Workshop at UC Berkeley as well as law courses at Université de Reims-Champagne- Ardenne in France.

Deni is a research and teaching fellow at the UCL LL.M programme in ‘Law and Economics of Regulated Industries: Between Competition and Regulation (2009-2012) and in ‘EU Competition Law’ (2011-2012).

Before joining UCL Deni worked as a trainee lawyer and qualified to practice law in Greece (Athens Bar Association).
