She has worked extensively with clients in all major government departments such as HM Treasury, the Department for Transport and the Department for Education; the wider public and voluntary sectors including NHS England and the Salvation Army; as well as businesses in sectors such as infrastructure and finance.

Fraser advises clients across a wide range of sectors on competition issues including merger cases, dominance assessments, and damages litigation arising from antitrust infringements. He has extensive experience in the mobile sector and regularly works closely with colleagues in Frontier’s telecoms practice to provide competition advice in this area. Fraser has also worked on cases across a number of jurisdictions and in recent years he has advised several high profile clients through the European Commission’s merger approval process.

Her work focusses on business strategy, innovation and regulatory strategy. As an expert in behavioural economics, Laura also advises clients on how to use behavioural insights to support strategic choices – both for commercial propositions and regulatory action.

Danail advises public and private sector clients on policy and regulatory issues. He has a particular focus on education and labour markets, and has provided economic advice to firms, government and regulators on a range of issues such as pay and qualifications in further education, funding and area cost adjustments in healthcare, and the labour market returns to different forms of education. Dan’s work often involves the use of large data sets and complex modelling to determine the impact of certain policy interventions.

Hanna works in Frontier’s Competition practice and has experience in follow-on damages litigation arising from antitrust infringements, as well as merger cases and abuse of dominance cases before the European Commission and national competition authorities. In particular, she works on cases in Germany and has advised clients, inter alia, in the automotive industry and the wholesale and retail industry.
