Professor Cyril Grunspan was born in Paris in 1971. He studied mathematics at the Lycée Louis-le-Grand and at the Ecole Normale Supérieure. He started his first PhD thesis in number theory at the University of Caen before leaving for Budapest to be a professor of mathematics in a French school in Budapest as part of his national service. Victim of a brutal and unexpected health accident, he gradually recovered and decided to resume a thesis in mathematical physics under the direction of Mr. Benjamin Enriquez. He defended his PhD thesis “Discrete Toda Theory and Quantum Homogeneous Spaces” in 2001 at the Ecole Polytechnique. His research then focused on Hopf-Galois extensions in link with quantum torsors, a notion he defined and deepened.
Several post-doc positions led him to Israel and Italy. There, he discovered the world of publishing. He volunteered as editorial director of a young publishing company and created a collection of short biographies of famous writers. In this collection, he wrote a short biography of Marcel Proust.
Afterwards he went back to France, he was for some time a professor of mathematics in a preparatory class for the “Grandes Écoles”. Then, he discovered financial mathematics and decided to study it extensively at the University of Paris VII.
Then, he moved to London and worked as a quantitative analyst in the interest rate market for an investment bank. He resigned in 2010 due to a family-related event and accepted a position of an associate professor at ESILV (École Supérieure d’Ingénieurs Léonard de Vinci), an engineering school located at Paris-La-Défense.
In 2012, he became head of the financial engineering department at ESILV and was the key player in the development of new areas of studies: actuarial science and fintech.
Under his initiative, ESILV became the first engineering school in France to give courses on bitcoin and crypto-currencies, the first school in the world to certify diplomas in the blockchain (in collaboration with Paymium) and the first school to offer blockchain programming courses.
Many companies, start-ups and institutions such as the Banque de France have been collaborating with the school and its students.
Cyril Grunspan is also the author of several articles on bitcoin (mostly visible on his Linkedin profile) and is regularly invited to participate in conferences on this topic. He discovered IOTA last year, wrote an article on his blog and reprinted on Linkedin. (English translated version), in addition to this he is co-organizer of the “Paris cryptofinance seminar”.
As if all of this was not enough, he recently published a paper with Ricardo Perez-Marco which corrects the mathematical part of Bitcoin’s founding whitepaper by Satoshi Nakamoto.
On joining IOTA
As a modest mathematician fascinated with crypto currencies and distributed ledger technology, the discovery of IOTA and Serguei Popov’s whitepaper last year has been a revelation.
For the first time it is possible to get rid of centralized miners who ruin the decentralized governance model of Bitcoin and other blockchains.
The idea of making validation an intrinsic property of using the network is a brilliant idea.
The IOTA whitepaper is interesting in many ways, I particularly like the use of the theory of large deviations as well as the utilization of random walks on Markov chains to study the underlying protocol.
All of this make me want to study IOTA deeply, even if I know that the mathematics behind IOTA is far more complex than the maths behind Bitcoin.
We are very happy to have Cyril join the IOTA roster, his broad expertise in numerous fields of mathematics is going to be very valuable as we are entering the next phase of IOTA development. As a mathematician he will work along side IOTA co-founder Serguei Popov, and his main focus will be on the fundamental mathematics of Tangle as well as formulas for a long planned new IXI module on top of IOTA which will greatly extend IOTA’s functionality.
