Eduardo is a researcher at the Centre for Complexity Science, Imperial College London. He also works within the financial services industry, developing quantitative methods for risk management and portfolio investment strategies.
His research is centred on the Financial Risk of Complex Systems, and it is fundamentally inspired by S. J. Gould’s structure of evolutionary theory and von Neumann’s automata theory. This effectively translates into constructing methods and frameworks centred on the development and implementation of evolutionary dynamic, nature inspired, quantitative methods to enhance the identification - and mitigation - of systemic, market, credit and liquidity risks within the financial markets and economic systems.
He has nearly 30 years of experience within the global financial services industry in the development and implementation of mathematical finance models and stochastic analysis to enable valuation and pricing of cash and derivative financial instruments, risk quantification strategies, and trade structuring.
Among past positions, he was the Head of Risk, Valuation and Governance of Lehman Brothers International Europe since its first day of administration, as well as the Head of Model Risk Methodologies for PwC’s Financial Services Risk and Regulation practice, and the Leader for the European Structured Finance Group for PwC’s Eurofirms.


To interact and collaborate with remarkable world researchers - with uniquely diverse academic traditions and background - in order to dialogically share new ideas and theories. Through this process, to contribute to the dissemination of complexity inspired methods to a wider audience within the financial industry and capital markets.


  • The dynamics of bankruptcy of companies as a result of ‘Punctuated Equilibrium’ events

    The research adopts a framework where companies are equivalent to nested organisms which are released into the wider environment upon bankruptcy. When comparing to real data, we aim to quantify and to better understand the impact of such dynamics to the resilience of the economic and financial systems.
