Project Acronym XS-Meta
MSCA Grant Agreement 956401
General description of the Project
XS-Meta is an Innovative European Training Network project with the main objective of training a new generation of researchers in concurrent material-structure design of high-technology structural systems, using functionally graded 3D-printed metamaterials.
The scientific challenge in XS-Meta is to take advantage of the metal 3D printing technology to perform a change of paradigm on how engineering structural design is performed, integrating the design of the metamaterial structure at the subscale with the engineering design of the component to develop a new generation of high-performance components. XS-Meta addresses the multiple scales of the problem, from microstructure of the material at the grain level, to the continuum-based engineering design of industrial components.
XS-Meta involves 11 partners from 7 different countries, including reference research groups in 7 leading academic institutions, one public research institute and 3 companies. XS-Meta involves different fields, from machine learning to computational and experimental materials science, manufacturing, applied mathematics, computational mechanics, and software engineering.
In the framework of this ITN, 14 early stage researchers (ESR) will be recruited with the purpose of developing research leading to a doctoral thesis. The specific profiles are listed below. The duration of each contract and of the thesis will be of 36 months. Starting date is expected between September 1st 2021 to March 1st 2022. Exact dates will be agreed between the selected candidates and the recruiting institution.
Selected candidates will be offered a fixed-term 36-month contract with the applicable benefits for the institution and country, including health coverage. Standard competitive EU-MSCA salaries are offered. The salaries are adjusted to each country living standards. Additional mobility and family allowances will be paid on the top of the salary.
To apply for these H2020-MSCA training positions, applicants must fulfil the following MSCA criteria:

- Applicant with already ESR status: Applicants must fulfill the requirements for enrolling in the PhD program of the hosting institution (or the associated academic institution in case of industry hosts). At the time of recruiting, an applicant who initiated a research career must be in the first four years of their research careers and cannot have been awarded a doctoral degree.
