Professor Julian Williams, BSc, MSc, PhD
Julian Williams completed his PhD in finance at the University of Bath in 2007, where he worked for a year as a lecturer in finance and accounting. In addition to teaching at the university Julian also worked as an equity hedge fund researcher for Auriel Capital LLP. In October 2008 Julian moved to the University of Aberdeen as a lecturer where he was then promoted to senior lecturer. Julian has published widely on the topics of financial regulation, risk management and portfolio management. His main interests lie in market microstructure, regulating complex derivative securities and the impact of the liquidity of these instruments on the cost of capital for individuals, companies and governments. Julian’s work has been commented on and referenced in the Financial Times, the Press and Journal and OECD publications.
A keen user of information technology, Julian’s recent research work has focused on applying regulatory theories, audit processes and risk management techniques to information security problems. Julian was the economics work package leader and Aberdeen principal investigator for the Technology Strategy Board project ‘Cloud Stewardship Economics’ led by HP Labs in Bristol and is currently the overall scientific director and work package leader for the European Commission FP7 project "SECurity ecONMICS " which focuses on information security and critical infrastructure, partnering with National Grid (the UK bulk electricity transmission operator), ATOS research (a large global consultancy) and the University of Trento (where Julian is a visiting member of faculty) among others. Julian is currently a standing member of the scientific committee for the workshop on the economics of information security (WEIS). During his time in Aberdeen, Julian built the Thomson Reuters EIKON financial information room for the University of Aberdeen’s new library and organized advanced workshops on market microstructure and liquidity on the Isle of Skye.
Julian Williams started at Durham University Business School in January 2014. He has published widely on the topics of financial regulation, risk management and portfolio management. His main interests lie in market microstructure, regulating complex derivative securities and the impact of the liquidity of these instruments on the cost of capital for individuals, companies and governments.
