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 staff members in Lund, Helsingborg, and Malmö. We are united in our strive to understand, explain, and improve our world and the conditions of human life.

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 significance for 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 critical and analytical thinking, solving problems independently using appropriate methods, 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 dissertation and a doctoral degree. More information about being a doctoral student at LTH can be found at lth.se.

Subject and Project Description

The upcoming launch of the European Spallation Source ERIC (ESS) represents a fantastic opportunity for science, opening new pathways to investigate and understand the internal structures and processes of materials, as well as to understand our past and the history of our universe. Neutron imaging (radiography and tomography) will be possible at the Odin instrument and, in combination with the unique nature of the ESS source, will provide new perspectives on materials and structures through the possibility of hyperspectral, multi-dimensional images containing intricate details about the distribution of chemistry, composition, deformation, and temperature. This project is part of the "Pillars for Imaging" initiative, aiming to demonstrate capacity and support the development of the ecosystem around the Odin instrument. Furthermore, the project will contribute to building a foundation for neutron imaging science at ESS from "beam-on-target" and beyond 2030, by establishing and demonstrating important 3D tomographic reconstruction methods to utilize Odin's capacity to address scientific questions and challenges across a broad spectrum of science.

Responsibilities

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

The responsibilities include:

• 3D/4D tomographic reconstruction of multi-/hyperspectral time-of-flight (ToF) neutron imaging data,
• exploration of best strategies for tomographic reconstruction of ToF transmission data and noise reduction methods,
• development of tomography and ToF data fitting algorithms,
• forward modeling of neutron/X-ray tomography at Odin,
• development of and participation in early scientific experiments at Odin,
• material analysis with ToF tomography and dual X-ray/neutron tomography using Odin (including image reconstruction and data analysis).

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