Research Topics

Current professional interest and research activity in chemical engineering especially in relation with environmental goals, eco-design of bio-chemical processes, impact and risk assessment and pollutant emission modelling.


Sustainable bio-chemical technologies through environmental assessment and eco-design approaches:

- Development of integrated modelling platforms for predictive and parameterized LCA dedicated to eco-design of bio-chemical processes. Platforms couple specialized and homemade IT tools for

Process Modelling & Simulation - LCA - Efficient Multi-Objective Optimization  


Methodological developments, new models and IT tools in Sustainability science:

- Building a new Life Cycle Assessment method (dynamic LCA) by including time dimension in value chains’ representation and dynamic functioning of processes;

- Thermodynamics-based assessment methods (Emergy, Exergy) - development and application in the field of industrial processes. 


Environmental impact and risk assessment of materials:

Application of thermodynamic, geochemical and mass transfer modelling to assess the environmental behaviour of materials under various environmental conditions - modelling of pollutants emission from materials, wastes and soils, and of the impact of pollutant release on water sources.



Teaching activity in the department of Process Engineering and Environment, INSA Toulouse. Teaching areas:

-chemical engineering

-environmental assessment tools (LCA) and eco-design of processes.
