Bertrand graduated from Ecole Normale Supérieure (Ulm) and has a Ph.D. in physics. Before joining Riskdata in 2000, Bertrand was conducting experimental research in plasma physics. He was dealing with collecting and analyzing large quantities of data stream coming from ionospheric radars. In 2016 he co-founded Quarisma Finance.
How this background allowed him to flourish in the risk management industry is still a mystery.
