2 Missions


In this project, within ESIEE School of Engineering, a founding member of Université Gustave Eiffel, the ESYCOM and LIGM laboratories join forces with the young start-up IZONICS, whose aim is to advance the maturation of an innovative technology for low-cost and effective detection and recognition of microplastic particles in water [1].

This technology is based on a combination of Raman spectroscopy and microscopic imaging [2, 3].
While Raman spectroscopy is fairly well mastered today, its effective combination with microscopic imaging has yet to be fully exploited. However, this combination could bring several advantages, from faster processing to the possibility of developing new methods for the analysis of microscopic images [4].

The objective of this project is to work and implement complete and efficient methods for the detection and recognition of particles, to offer new opportunities and applications for water analysis.

Several steps will have to be carried-out, such as validation of the parameters of the data acquisition
chain, evaluation and development of data analysis methods, and definition and implementation of
demonstration applications. A significant part will also be devoted to the creation of the dataset (non-existent today for the microscopic imaging part).

If the candidate is interested, he can optionally contribute to the implementation part of the
hardware system.

3 Activities


– join a research lab to conduct innovative R&D and join a startup team to contribute to its developement
– conduct research in the field of data analysis in the field of AI-based methods applied to microplastic particle detection and recognition
– participation in the implementation and prototype validation
– coordination of development outsourcing
– supervision of internship students can be considered
