About the Department

The Department of Materials Science and Engineering aims to be an environment for successful and valuable research and education with a focus on materials science solutions for important societal challenges. Our department is an exciting workplace with research in a broad technology-related area, from basic research to large-scale applied research, and close contacts with students through the department's involvement in engineering and master's programs. Our research and teaching are conducted within seven divisions with different research focuses, as well as a division that provides support and service. The department is an international place to work, and has around 230 active co-workers.

About the division

The Division of Applied Mechanics is part of the Department of Materials Science and Engineering at the Ångström Laboratory. We conduct research in experimental and computational mechanics with application areas primarily within the life sciences, materials and structural development, and energy-related fields. The research carried out is multidisciplinary and ranges from applied projects in close collaboration with industry to academic fundamental research. A doctoral degree in the field provides many exciting future opportunities both in academia and in industry, nationally as well as internationally.

Project description

The sky-rocketing prevalence of impact-induced bone fractures, driven by an aging population and a growth in traumatic incidents such as traffic collisions and critical falling, is leading to a higher demand for bone repair methods. Biodegradable metal alloy 3D-printed lattice scaffolds are aimed to sustain mechanical loads and at the same time stimulating bone growth into the lattice while the lattice itself degrades and eventually the injured location is completely replaced by newly formed bone.

With financial support of the Swedish Research Council, [SW1] the research project focuses on the development and implementation of high-performance numerical algorithms for multiphysics simulation of impulse-initiated fractures in porous structures using phase-field models. Phase-field theories are beneficial due to their flexibility in capturing coupled physical phenomena across multiple length and time scales. The developed algorithms will primarily be implemented on computer clusters to simulate porous and/or randomly structured heterogeneous materials soaked in fluids with the aim of designing implants for the treatment of severe bone fractures and tissue regeneration. A natural part of the project is to conduct sophisticated experiments using ultra-high-speed MHz X-ray in-situ imaging of bone/lattice systems soaked in fluid and subject to impulse loads at the ESRF synchrotron to support the computer simulations.

A long-term goal is to provide useful numerical engineering tools to Swedish industry for an optimal design of load-bearing structures with complex geometries in harsh environments.

Duties

The main duty for a doctoral student is to devote themselves to their research studies which includes participating in research projects and PhD courses. The work duties can also include teaching and other departmental duties (no more than 20%).

Being a PhD student means independently running projects within a specific subject. You collaborate on an ongoing basis with other doctoral students and researchers to create results within various projects and have one or more supervisors for support during your doctoral studies. However, you work independently to a great amount, e.g. by working in a laboratory environment and writing articles for journals and for results for your doctoral thesis. Usually some form of half-time seminar is included after about half of the doctoral studies.

When you are admitted to doctoral studies, you are offered employment as a doctoral student. A position as a doctoral student at Uppsala University corresponds to full-time PhD education for four years.

Your tasks involves activities from theoretical development in material modeling, to programming in-house developed codes, as well as conducting experiments locally and nationally (in larger facilities such as synchrotrons).

Requirements

• Master’s degree in Engineering Physics, Mechanics, Computational Science or related fields, or other equivalent education
• Documented experience and knowledge in mechanics
• Good oral and written skills in English.

Rules governing PhD students are set out in the Higher Education Ordinance (1993:100) chapter 5, §§ 1-7 and in Uppsala University's rules and guidelines.

Additional qualifications

• Documented experience and knowledge physics, and scientific programming
• Proficiency in mathematical modeling/analysis
• One or more of the following subjects: continuum mechanics, computational mechanics, numerical analysis for differential equations, numerical linear algebra, thermodynamics, and programming languages such as Python, C/C++, Fortran or Matlab. [SW2]

Great emphasis is put on personal qualities such as the ability to independently plan and carry out work. You have a good ability to work towards set goals and you work focused to achieve them. In this, you have an ability to focus, even during periods of high workload. You have good communication skills, where through this quality you cooperate well with others. You also have a good ability to write academic text.

Your application must include

• A short cover letter in which you describe yourself, why you want to do a PhD and why you are suitable for this position. 
• CV (max 2 pages)
• A certified copy of your master's degree and your course grades.
