Activities

Within TotalEnergies OneTech, the BioHub roadmap aims to provide competitive bio-based raw material alternatives for the production of biofuels (particularly SAF) that comply with current regulatory requirements and volume demands. Understanding the evolution of various factors such as climate change, the bio-based raw material supply chain, sustainable carbon use, and the management of agro-agricultural resources and non-recovered waste are key to producing aviation biofuels sustainably

Quantifying global Bio Feedstocks presents several challenges: data availability, high biomass variability and competition between different usages which can lead to inaccurate estimates. Furthermore, the existing studies and models concerning biomass availability are often difficult to compare, as they apply different criteria (e.g. technical, economic or sustainable) to overall potentials and these studies are not harmonized from one study to other nor always transparently documented.

Aware of the importance of having reliable data on the availability of global biomass, the Upstream Bio Feedstocks team has developed an internal methodology to support TotalEnergies' ambition in bio-based molecules and achieve carbon neutrality by 2050.However, it is critical to also estimate potential biomass availability at future horizons (e.g. 2030, 2040 or 2050) since this assessment may be integrated into TotalEnergies strategic portfolio.

The Upstream Bio Feedstocks team from the Biofuels program is looking for a motivated postdoc/young scientist candidate to:

• prospect biomass availability by machine learning tools (IA)
• estimate potential biomass by machine learning approach while quantifying uncertainty and correcting bias in specific time horizons.
• Build spatial and temporal dynamic models

The position is based at Solaize (Lyon) and we propose a 18-month fixed-term private law contract to start in September 2025.

Candidate Profile

This position is for you if:

• You hold a PhD in Computer Sciences (less than 3 years) or equivalent practical experience or related technical field
• You demonstrated expertise in machine learning research
• You have strong mathematical skills, ability to formulate a research problem, design, implement and communicate solutions
• You are comfortable with modelling tools like Aspen, Python,
• You are fluent in English and French could be an option.
• You have good communication skills and you are able to work autonomous
