About us

Inside Loop provides consultancy in mathematics and computational physics. Our core business is the development of algorithms for mathematics and computational physics. We have experience into turning ideas coming from academic research into industrial products. We also can help you bring up to date your scientific code to the latest technologies. Our products enforce:

  1. Correctness: Scientific software is not just about giving back numbers to the user. Their results needs to be reliable. That’s why all Inside Loop numerical algorithms extensively use Unit Testing to be checked against analytical solutions.
  2. Maintenance: Softwares always tend to live longer than expected. That’s why their maintenance cost should be as low as possible. At Inside Loop, we strongly believe in keeping software architecture simple. In our design, flat hierarchies and simple classes are favoured over deep inheritance trees.
  3. Performance: Wether you have high computation requirements, or your program needs to run on energy efficient devices, you need software designed with performance in mind. That’s why we favour Data-oriented design in our applications.

We also provide training in scientific software development.




Schlumberger is the world’s largest oilfield services company. We provide consultancy in reservoir simulation and uncertainty quantification for their main research laboratory SDR located in Cambridge, MA (USA) close to MIT and Harvard.


Teclis Instruments is the leader in innovation for instruments market of physical chemistry of surfaces and interfaces since 1991. We develop their image-analysis based software to compute surface tension.

Wolfram Research:

Founded by Stephen Wolfram in 1987, Wolfram Research develops Mathematica, the leading computer algebra system and numerical software available on the market. We provide training in Mathematica to their clients.



François Fayard:

François graduated from École Normale Supérieure de la rue d’Ulm (Paris, France), where he passed the Agrégation in Mathematics and worked on the Boltzmann equation with Pierre-Louis Lions and Cédric Villani. He has 9 years of experience in teaching mathematics and computer science to students preparing the entrance exam to École Polytechnique, ENS, ESPCI, École Centrale and Agronomical Schools. He later joined SDR, the main research center of Schlumberger (Boston, MA, USA), where he worked with T.S. Ramakrishnan on reservoir simulation, developing numerical code and working on analytical solutions to partial differential equations.
