Vacant job

Lund University was founded in 1666 and is consistently ranked among the world's leading universities. We have approximately 46,000 students and 8,500 employees in Lund, Helsingborg, and Malmö. We are united in our strive to understand, explain, and improve our world and the conditions of people.

Description of the Department

Strength of Materials was the first department established at LTH and is today part of the Department of Civil and Environmental Engineering. The department operates in an international environment and maintains contacts with research organizations and companies both nationally and internationally. Today, the Department of Strength of Materials consists of approximately 25 employees, of whom about 15 are doctoral students. The working atmosphere is open and welcoming, striving to provide every employee with the opportunity to develop both personally and professionally.

The subject of Strength of Materials deals with methods and principles for describing deformable bodies. It is a fundamental subject within mechanical engineering and of basic importance to related disciplines. The problems and issues addressed within Strength of Materials have clear relevance for industrial applications.

Research in Strength of Materials at LTH is particularly focused on constitutive mechanics, numerical methods, microstructural mechanics, structural optimization, and experimental methods. The department also has strong activity in X-ray and neutron methods for materials research.

Being a Doctoral Student

As a doctoral student, you are both admitted as a student and employed at Lund University.

As a research student, you are trained in a scientific approach. This can be briefly described as gaining practice in thinking critically and analytically, solving problems independently using appropriate methodological choices, and developing research ethics awareness. Additionally, doctoral students are given the opportunity to work on projects, develop leadership skills, and enhance pedagogical abilities. Throughout your studies, you are guided by supervisors. The doctoral studies conclude with a thesis and a doctoral degree. More information about being a doctoral student at LTH can be found on lth.se.

Subject and Project Description

This doctoral project is part of the "RAPTOR" project, funded by the NovoNordisk Foundation, and is a collaboration between Lund University, the University of Copenhagen, and the Technical University of Denmark. The overarching goal of the RAPTOR project is to develop the next generation of foundational models for the analysis of 3D volumetric data to enable accelerated classification, segmentation, and quantitative characterization of the multiscale structures found in X-ray microtomography images. The development and training of the foundational model is already underway and is based on large volumes of existing data from various sources, including synchrotron and laboratory micro-CT scanners, medical imaging datasets, and electron microscopy. During the project, RAPTOR will be further developed and applied to materials and biomedical research challenges.

In this doctoral project, you will contribute to the development of RAPTOR and related methods, with a particular focus on utilizing the model to classify, segment, and quantitatively characterize the multiscale structures and processes in materials, including metals, fiber-based materials, and porous/granular materials. You will develop protocols and pipelines for scanning, curation, and analysis of large 3D datasets to explore material structures and heterogeneity. You will also develop and perform in-situ experiments with 4D X-ray tomography to explore the relationships between structure, properties, and processes.

Responsibilities

Your primary focus will be on your doctoral education, which includes participation in research projects, doctoral education courses, seminars, and conferences.

The responsibilities include:

• development of strategies for high-throughput 3D/4D X-ray tomography to study material structures and heterogeneity at multiple scales;
• development of in-situ/operando experiments to study material processes under, for example, mechanical, thermal, or fluid loading;
• development of efficient image processing/analysis methods for large volumes of 3D/4D data, including classical and machine learning-based methods;
• participation in the development of the RAPTOR model;
• execution of experiments with X-ray tomography in laboratory and synchrotron facilities;
• establishment of protocols for curation of large datasets;
• material analysis using 3D/4D X-ray tomography and image analysis;
• statistical analysis of large volumes of 3D/4D datasets in connection with, for example, mechanical test data, and linking this to modeling/simulation within solid mechanics.

The responsibilities may also include participation in teaching and other departmental activities (however, max 20% of working time).
