Thomas is a DPhil student at Brasenose College. He researches the potential anti-competitive effects of horizontal shareholding by institutional investors. Horizontal shareholding exists when the leading minority shareholders of horizontal competitors overlap, which is increasingly the case in many industries. Thomas takes a holistic approach to this topic by integrating competition law research with insights from corporate governance and corporate law scholarship, economic theory, and empirical economic research.

Thomas' research is funded by Oxford's Law Faculty (merit scholarship) and Brasenose College, where he is a Senior Hulme Scholar. Professors Luca Enriques and Martin Schmalz supervise his research.

Thomas obtained a Magister Juris degree (Distinction) from the University of Oxford, graduating first in class (Clifford Chance prize). He also holds a Master of Laws from KU Leuven (summa cum laude), where he graduated first in class.

Thomas used to practise law in Brussels and London, with Linklaters LLP and then Freshfields Bruckhaus Deringer LLP. He was also a Senior Advisor at DRD Partnership. In March 2022, Thomas joined the General Court of the European Union as a référendaire (legal secretary / senior legal staff member) in the Chambers of Judge David Petrlík. 

Thomas used to co-convene Oxford's EU Law Discussion Group and taught EU law as a teaching assistant at KU Leuven.
