  2016 - maintenant BIG DATA ANALYSIS:
  - Computation of the main metrics (power, heart rate, speed…) and complete analysis of the training or race sessions
  - Determination of new rider parameters such as workload, shape, physical capacities, …
  - Finding specific patterns on the data to avoid overtraining and to estimate further progress
  - Computation of the optimal training plan such that the rider reach his best shape on the d-day
  
  PHYSICAL MODELLING:
  - Creation of a model to compute the theoretical power of the rider given aerodynamic and physiological rider capacities as well as the GPS coordinates and the weather conditions
  - Machine learning algorithms to determine the aerodynamic feature (i.e. the drag coefficient) of the rider
  
  PROFESSIONAL TEAM ALGORITHMS:
  - Creation of algorithms to simulate specific types of stage or race scenarios
  - Computation of the optimal power distribution for an individual or team time trial
  - Determination of the optimal strategy for the team and his leader in the final climb of a mountain stage
