About me

My research focuses on the evaluation and design of tax policies, particularly those affecting top earners and High Net Wealth Individuals (HNWIs). I combine technical expertise in tax law with quantitative methods and data science, via collaborations with economists and other social scientists. I am Director of the Centre for Analysis of Taxation (CenTax), a research centre dedicated to improving public understanding of tax and helping to design a better tax system, through research that is academically rigorous and relevant to policymakers and the public.

I convene two masters-level courses on taxation. LL4CG Tax Policy and Design is an introduction to the evaluation and design of tax policies using a variety of disciplinary perspectives including economics, philosophy, and political science, as well as law. LL4CO Taxation of Wealth examines how the UK taxes wealth (and the wealthy) and evaluates options for reform of existing capital taxes. I also teach an undergraduate course on LL293 Tax and Tax Avoidance.

Before joining LSE in 2014, I studied Law as an undergraduate at Cambridge (2005-08) and as a postgraduate at Oxford (2009-10). I completed my doctorate at Corpus Christi College Oxford, where I also taught as a College Lecturer (2011-14). My PhD research focused on the assessment of damages in private law, and theories of loss and causation. In 2016, I got married and took my wife’s name (…we flipped a coin). Consequently, my publications prior to 2016 are listed under my previous name, Andrew Dyson.
