Associate professor. Associate editor for Quantitative Finance, Applied Mathematical Finance, Journal of Economic Interaction and Coordination, Journal of Statistical Mechanics: theory and experiments.
- Agent behaviour (trader, investment fund, programmer). Recently, my interest has focused on agent-resolved data and aims at understanding what triggers activity and characterizing collective optimization in very heterogeneous populations.
- Statistics: I have introduced a new way to build nonparametric statistics for location and distribution equality tests, called r-statistics. One paper is about their power and another about their efficiency as an estimator of Sharpe ratios.
- Machine learning applied to financial data and fundamental economic data. E.g. Google Trends: see a comment and a paper.

Source codeThere is no reason to open-source mathematical computations and not computer code when submitting a paper. My repositories may be found on github.com. Some recent contributions:
- sharpeRratio (), an R package available on CRAN that implements the moment-free estimator of this preprint . A Python package of the same estimator, written by by Amir Sani, is available on pypi.
- ReplacementBootstrap, an R package available on github.com repository that implements an max-entropy based bootstrap procedure, written in collaboration with Amir Sani. See this paper.
Teaching resourcesCurrent courses
- Physique des marchés (2012-), a mechanistic approach to financial market modelling and algorithmic trading, Applied Mathematics option for third-year students of CentraleSupélec.
- Financial Big Data at EPFL (Master in Financial Engineering) (2016-). The whole aim is to teach how to deal with annoyingly big data, or annoyingly computationally intensive calculations (hint: clean, simplify, distribute, accelerate).
- Algorithmic Trading (2018-), MSt in Quantitative Finance, Solvay Business School, Brussels, Belgium. In short, big data and machine learning applied to trading.
- Big data, MSt in Quantitative Finance, Solvay Business School, Brussels, Belgium (2017)
- I have been teaching a lecture entitled “Inefficient Markets” at HEC Lausanne for 5 years. It was about why financial markets cannot be efficient. The course plan was as follows: 1) financial markets deconstruction (behavioural finance), 2) reconstruction (agent-based modelling), 3) the art of speculative strategy backtesting. Lecture slides are available there.
InternshipsI will gladly supervise Master theses on a topic that is related to my interests (and, incidentally, abilities). Please check that yours are compatible with mine before contacting me.
