About Me

A Swiss national whose family background extends to the UK and Greece, I have lived in five European countries and in the USA, acquiring an acute cross-cultural awareness and a truly international perspective.

Following a Master’s degree in Economics from H.E.C. Lausanne and an MBA at London Business School, I spent the first 17 years of my career as Managing Director reshaping companies acquired by an international group, before focusing solely on the business integration of broad-scale international mergers and acquisitions, in a number of different industries, over two decades.

Author of “Perfect M&As – The Art of Business Integration”, I have lectured to Executive MBA classes as well as Management Development programmes at HEC Paris, London School of Economics, Manchester Business School, and since 2016 at University of Oxford (Saïd Business School).
