Research project

Development of fiber optic probes for monitoring critical quality attributes of bioprocesses

Description

A PhD project is offered within the research teams of Professors Younès Messaddeq (Department of Physics, Engineering Physics, and Optics; https://ymlab.ca/) and Alain Garnier (Department of Chemical Engineering) at Université Laval. This project is part of an initiative supported by the Eastern Canada Pandemic Preparedness Hub to accelerate vaccine production in Canada. It focuses on developing innovative strategies for monitoring the quality of cell cultures used in the production of viral vectors and recombinant proteins. The research environment is enriched by collaborations with renowned research centers such as CERVO, as well as by strategic partnerships with governmental and industrial organizations, including the National Research Council of Canada, INO, and Ivano Biosciences.

The main objective of this research project is to develop fiber optic probes for in situ and real-time monitoring of bacterial cultures in bioreactors. These probes will aim to measure critical parameters of biomanufacturing processes, such as biomass, culture medium components, and metabolites, to promote efficient optimization and rigorous production control. Specifically, probes based on Raman spectroscopy will be designed, manufactured, and tested. Performance will be validated on various bioreactor formats and different bioprocesses.

Tasks include:
- Fabrication of fiber optic probes
- Optical spectroscopy (Raman)
- Bioprocess monitoring
- Data acquisition and chemometric analysis
