Charles-Albert Lehalle

I'm a mathematician (PhD on stochastic and nonlinear control using artificial neural networks, directed by Pr Robert Azencott).

I'm the main author of OCAMAWEB (an ongoing version is available here: OCAMAWEB) which is a literate programming tool in ocaml. I initially built it for Matlab code. Now it has configurations files to work with awk, SAS, S-plus, and a lot of other languages.

I worked :

  • 4 years at the Renault Research Center - as Research Engineer
  • 5 years at MIRIAD Technologies (French SME dedicated to online diagnosis and monitoring of huge dataflows) - as Head of the algorithmic devlopments and advanced studies
  • 2 years at EXANE-BNP-PARIBAS in the Trading & Arbitrage research team

Now I work at CA Cheuvreux (CALYON group) as head of the quantitative research team. Our research are mainly focused on high frequency trading, statistical arbitrage, market microstructure and algorithmic trading.
