Offer Description

The Doctoral Candidate (DC13) will be hired for two consecutive 18-month periods as part of the “Bridging Models at Different Scales To Design New Generation Fuel Cells for Electrified Mobility (BLESSED)” project which is funded through the Horizon Europe Marie Skłodowska-Curie Actions (MSCA) Doctoral Networks. The DC13 individual project will be realized at: (a) the R&D Division of Matgenix in Charleroi, Belgium, under the supervision of Prof. G.-M. Rignanese and Dr. D. Waroquiers, and (b) the Department of Chemistry of the University of Crete (UoC) under the supervision of Prof. G. Froudakis. DC13 will be enrolled in the PhD program of the University of Crete, Greece. A one-month secondment at the Statistics section within the Mathematics Department at Imperial College in London/UK is foreseen.

Microporous layers (MPL) is known to improve the PEMFC (Proton Exchange Membrane Fuel Cell) efficiency, especially under wet operating conditions but explanations for this improvement are still under debate, with the process being not yet fully understood. This hinders the development and optimization of new MPL compositions with superior performance. The objective of DC13 is to improve the efficiency of MPLs, especially under wet operating conditions, by developing atomistic models of MPL materials and performing ab-initio MD simulations of the water-MPL surface interactions.

To this end, DC13 will (i) develop realistic atomistic models of MPL materials with different compositions to perform ab-initio molecular dynamics (MD) simulations of water molecules on MPL surface models, (ii) construct a DB of MPL materials and compositions with different model systems at different scales, (iii) validate a multi-scale methodology combining ab-initio simulations with machine-learning (ML) to perform classical MD on large water-MPL surface models, (iv) better understand the performance improvement brought up by MPL in PEMFC systems, (v) identify the important parameters of compositions and porosities to propose new candidate MPL systems with potentially better performance.

Additional Information

Benefits

The selected candidate will receive a salary in accordance with the MSCA regulations for DCs. The gross salary includes a living allowance (€3400 per month subject to MSCA Country Correction Coefficient, namely 100% for Belgium and 81,6% for Greece), a mobility allowance (€600 per month) and a family allowance (€660 per month), if the researcher has family (‘Family’ means persons linked to the researcher by (i) marriage or (ii) a relationship with equivalent status to a marriage recognized by the legislation of the country where this relationship was formalized or (iii) dependent children who are actually being maintained by the researcher). The guaranteed (EC) funding is for 36 months.

Eligibility criteria

Applicants can be of any nationality and must hold a Master of Science degree (or equivalent) in Engineering, relevant to the aforementioned topics. They need to fully respect the following eligibility criteria:

(a) Must be doctoral candidates, i.e., not already in possession of a doctoral degree at the date of the recruitment.

(b) Must undertake transnational mobility. Researchers must not have resided or carried out their main activity (work, studies, etc.) in Belgium for more than 12 months within the 36 months immediately before their date of recruitment. Compulsory national service, short stays such as holidays, and time spent as part of a procedure for obtaining refugee status under the Geneva Convention are not taken into account.

Selection process

The candidates should send a CV, cover letter, BSc and MSc degrees (certified copies plus translation in English), examples of your coding in python packages (e.g., github/gitlab links) and two letters of recommendation. Copies of publications could be sent later on, upon request. Personal interviews might be asked.

All applications must be mailed to both david.waroquiers@matgenix.com  and frudakis@uoc.gr with subject: “BLESSED-DC13-Application”.

The outcome of the evaluation process will be announced by end of July 2023. The contract is expected to start on the 1st of September 2023.

Additional comments

During the first 18-months period, DC13 will be working at the R&D Division of Matgenix in Charleroi, Belgium. Within a team with a strong expertise in computational materials science and chemistry, workflow automation and machine-learning, DC13 will have the opportunity to learn, develop and apply state-of-the-art techniques for high-throughput simulations as well as specific machine learning models tailored to materials and chemistry. This will provide a step stone for the benefit of the BLESSED project.

The second 18-month period DC13 will be working in the Computational Chemistry group of Chemistry Department of the University of Crete. Taking advantage of and using the strong expertise of the group in various fields of computational chemistry and materials science (ab-initio quantum chemistry techniques, Monte Carlo and Molecular Dynamic simulations together with Machine Learning etc.) for the benefit of the project BLESSED is expected. The UoC provides an HPC computing environment which is available for use in connection with process modeling of the project.
