Her area of specialisation was derivatives and financial engineering.

Martha is interested in whether investors can achieve the benefits of international diversification indirectly by investing in internationalised firms.  Although home bias is widespread in investments, it may be overstated if this indirect exposure is not counted as foreign investment.




Dr O’Hagan-Luff has conducted research in firm internationalisation, behavioural finance, and entrepreneurship. Her current research interest are in sustainable finance, ESG investing and green bonds. Her research contributes to the Sustainable Development Goals 3, 8 and 13.
