Matthieu Wyart

Wyart studied physics, mathematics and economics at the Ecole Polytechnique in Paris and obtained a degree with honors in physics in 2001. In 2002, he received a diploma in Advanced Studies in theoretical physics with highest honors from the École normale supérieure in Paris. He then joined Jean-Philippe Bouchaud and Marc Mézard at the Service de Physique de l'Etat Condensé (SPEC) at Saclay Nuclear Research Centre (CEA Saclay) in Paris as a doctoral student.{{Cite journal|last1=Bouchaud|first1=Jean-Philippe|last2=Gefen|first2=Yuval|last3=Potters|first3=Marc|last4=Wyart|first4=Matthieu|date=April 2004|title=Fluctuations and response in financial markets: the subtle nature of 'random' price changes|url=http://www.tandfonline.com/doi/abs/10.1080/14697680400000022|journal=Quantitative Finance|language=en|volume=4|issue=2|pages=176–190|doi=10.1080/14697680400000022|arxiv=cond-mat/0307332|s2cid=219718300|issn=1469-7688}} In 2006, he gained a PhD in theoretical physics and finance for a thesis on electronic markets titled On the rigidity of amorphous solids. Price fluctuations, Conventions and Microstructure of Financial Markets.{{Cite thesis|title=On the rigidity of amorphous solids.

In particular, some of his recent research is focused on the classification of the elementary excitations controlling the linear and the plastic response in amorphous materials.{{cite journal|last1=Ji|first1=Wencheng|last2=de Geus|first2=Tom W.
