Lecturer in Finance and director of the MSc Finance (Asset Management) in Cork University Business School, University College, Cork. Research interests focus on quantitative investment strategies, portfolio management and risk analysis across multiple asset classes. I focus on research that is both suitable for publication in high ranking journals and has practical impact on the finance industry. My research and teaching is informed by significant industry experience as a quantitative  investment manager, with recognized excellence in both the traditional (Best UK Equity Fund – Financial Times) and alternative (Best Equity Market Neutral Fund – Euromoney) sectors. I co-founded Aphelion Capital, an equity based hedge fund manager which reached $1.2bn asset under management.
