Dr Aline Métris

Originally a biotechnologist, now working in the field of predictive microbiology. Joined the Institute of Food Research in 2000.
Graduated in Chemical Engineering, her PhD was on the modelling of biofilters, biological reactors to filter polluted air.
Since joining the Institute, has been participating in several projects funded by UK government and EU for the development and validation of mathematical models.
Her current activities concern the development of modelling at the single cell level and linking Predictive Microbiology to risk assessments.

Main interests:

Databases on microbial responses to food environments.
Modelling the variability of the growth kinetics of food pathogens within a same population.
Integrate databases information and modelling techniques with low number of cells into risks assessments.
Use the bio-chemical constraints of the metabolic network of the bacteria to predict their growth.
