About the Project

Short overview of PlasmACT:

The PlasmACT network brings together 5 beneficiaries and 10 associated partners, located in 5 different countries (Germany, France, Netherlands, Belgium, and Luxembourg). Eight Doctoral candidates will enjoy a multi-disciplinary and international environment with plenty of training opportunities and exchange with all institutions involved in the network.

Project Description:

The quality of human (and veterinary) health care systems substantially depends on key innovations. Often, these were driven by the field of physics, followed by interdisciplinary and inter-sectorial actions in engineering, chemistry, biology, and medicine. By using beyond state-of-the-art plasma multijet technology, the primary technical objective of PlasmACT is to support skin cancer prevention by medical gas plasma therapy of Actinic Keratosis.

This project will be supervised by Dr. Eric Robert, CNRS Research Director, head of the plasma for biomedical applications group at GREMI. The PhD candidate will take care of the plasma jet's physical and electrical characterization, optimization, and safety evaluation. The student will compare different configurations of plasma jet and multijet reactors. The student will learn to use an ample variety of instruments and techniques such as iCCD cameras, Schlieren, optical emission and absorption spectroscopy, electrical high voltage measurements, infrared cameras. The data and insight acquired by the student will contribute to the improvement of the multijet technology and to the final development of a medical device based on this. The PhD student will also acquire knowledge on EU medical devices guidelines with a special focus on novel international guidelines for plasma medical devices. In addition, two secondments to an academic and industrial partner institution are already planned to broaden the network and differentiate the student's skills and knowledge. Furthermore, the project provides ample opportunities for professional exchange and networking with other academic and industrial partners. At the end of the project, the PhD student will likely have acquired the following competences:

-             Research and Development methodology

-             Advanced knowledge in cold plasma physics

-             Knowledge in medical devices international standards

-             Presentation and reporting skills

-             European network of contacts both in the academic and industrial sector

The expected starting date is in June 2024.

About GREMI:

GREMI is a joint laboratory of CNRS and the University of Orleans. Research focuses on plasma and laser processes and their applications in various fields: e.g., energetics, materials, microelectronics, nanotechnologies, biology (medicine, agriculture, and cosmetics), metrology, radiation sources, propulsion, transport, and environment. GREMI gathers 22 tenured researchers and research faculty members, about 25 doctoral and post-doctoral researchers, and 11 CNRS engineers, technicians, and administrative staff. In addition, GREMI is associated with Polytech’Orléans engineering school, one of three faculties at the University of Orléans. Founded in 1306, the University of Orléans is one of the oldest European universities and currently enrolls 19,000 students.
