We invite applicants for a PhD position in luminescence physics at the Department of Physics (DTU Physics), Technical University of Denmark.

The positions will push forward the emerging field of Geophotonics — a novel paradigm that explores the interaction of light with natural crystalline materials to decode the dynamics of Earth's surface.

The positions offer a unique opportunity to contribute to fundamental advances in solid-state physics, while applying luminescence-based techniques to pressing questions in Earth system science.

The positions are funded by the ERC Advanced Grant LUMIN. This cutting-edge interdisciplinary project aims to understand charge transport in the natural mineral feldspar, unlocking new ways of measuring the rates of Earth surface processes — from weathering and erosion to sediment transport and landscape evolution.

Your research will focus on Confocal microscopy of point defects and trapped charges for applications in luminescence thermochronometry and rock surface dating.

You will be part of the dynamic and interdisciplinary LUMIN team, which includes engineers, scientists, postdocs, and PhD students working collaboratively at the interface of physics and Earth science.

This project offers a rare opportunity to engage in groundbreaking research with high impact across both academic and industrial domains. The scientific outcomes are expected to be significant in:

• Earth system science – by improving models of Earth surface evolution and enabling better predictions of landscape response to climate change.
• Engineering and applied physics – including the design of next-generation artificial phosphors and radiation dosimeters for use in medicine and other industries.

Responsibilities and qualifications
The exact research focus will be shaped in dialogue with you, depending on your expertise and interests. You are expected to be an independent researcher and take the lead on the project assigned to you. You are curious, problem-solving oriented and passionate about working in a team. You will lead the publication of results in high-impact scientific journals.

You have a strong background in physics, geophysics, materials science, computation, engineering, or a related discipline. Hands-on research experience in one or more of the following areas will be considered an advantage:

• Luminescence confocal microscopy and image processing
• Optical bench instrumentation – set up and alignment
• Scientific software development
• Lasers

You should possess strong communication and academic writing skills in English.

You must have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree.

Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see DTU's rules for the PhD education.

Assessment
The assessment of the applicants will be made by a hiring committee headed by Prof. Mayank Jain.

If you are applying from abroad, you may find useful information on working in Denmark and at DTU at DTU – Moving to Denmark. Furthermore, you have the option of joining our monthly free seminar “PhD relocation to Denmark and startup “Zoom” seminar” for all questions regarding the practical matters of moving to Denmark and working as a PhD at DTU.

Application procedure
Your complete online application must be submitted no later than 25 June 2026 (23:59 Danish time). Applications must be submitted as one PDF file containing all materials to be given consideration. To apply, please open the link "Apply now", fill out the online application form, and attach all your materials in English in one PDF file. The file must include:

• A letter motivating the application (cover letter)
• Curriculum vitae
• Grade transcripts and BSc/MSc diploma (in English) including official description of grading scale

You may apply prior to ob­tai­ning your master's degree but cannot begin before having received it.

Applications received after the deadline will not be considered.

All interested candidates irrespective of age, gender, disability, race, religion or ethnic background are encouraged to apply. As DTU works with research in critical technology, which is subject to special rules for security and export control, open-source background checks may be conducted on qualified candidates for the position.

At DTU Physics, we perform research, teaching, and innovation in experimental and theoretical physics with the overall aim to benefit society. We contribute to the transition to sustainable energy via research and innovation in catalysis, Power-to-X, and nuclear energy solutions. We design and develop new functional materials, contribute to advances in geosciences and life sciences, and we develop and exploit quantum physics and quantum technologies.

The Luminescence Physics and Technologies section (UMPHYS) where the PhD is hosted offers a vibrant, collaborative, and international research environment. Colleagues come from diverse backgrounds and nationalities, creating an inclusive and inspiring atmosphere where knowledge sharing and interdisciplinary work are highly valued. The section has state-of-the art laboratories for measuring defect-based luminescence from wind bandgap materials.
