Are you passionate about using experimental physics and mathematical methods to accelerate the green transition and address climate change? Do you want to transform the way we conduct and interpret tomorrow’s fusion experiments? Do you have a background in plasma physics, computational physics, inverse problems, or tomography? 

Then this PhD opportunity at the Technical University of Denmark (DTU) might be the perfect fit for you. We're seeking a highly motivated PhD student to join an interdisciplinary collaboration with experts in plasma diagnostics, computational plasma physics, and tomography.

Responsibilities and qualifications
This PhD project aims to build a next-generation framework for measurements of energetic particle distribution functions by tomographic inversion of measurement data. You will encode prior knowledge of the collisional processes in tokamak fusion plasmas using sophisticated numeric simulation codes, which will enable you to analyze data from tokamak experiments. You will be part of a team pursuing the development of novel integrated data analysis diagnostic tools that address key challenges in the field of energetic particle physics in fusion plasmas, such as instability drive by energetic particles and anomalous energetic particle transport due to instabilities. 

The project offers an excellent opportunity for interdisciplinary work within plasma diagnostics, tomography and computational plasma physics. We are looking for a candidate with extensive experience in these disciplines. The successful candidate will have a MSc in Physics, or related areas, as well as a general interest in mathematical and computational physics. The successful candidate will display good communication skills in English, both written and spoken, be innovative and be able to work both independently and in cross-disciplinary teams, as well as with international academic collaborators.

You will be assessed against the responsibilities and qualifications stated above and the following general criteria:

• Knowledge in plasma physics, tomography and inverse problems, or computational physics, or preferably several of these fields
• Knowledge of programming
• Communication skills

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 . 

We offer
DTU is a leading technical university globally recognized for the excellence of its research, education, innovation and scientific advice. We offer a rewarding and challenging job in an international environment. We strive for academic excellence in an environment characterized by collegial respect and academic freedom tempered by responsibility.

Salary and appointment terms 
The appointment will be based on the collective agreement with the Danish Confederation of Professional Associations. The allowance will be agreed upon with the relevant union. 

The period of employment is 3 years. The starting date will be as soon as possible according to mutual agreement.

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 26 January 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.

Department of Physics
At the Department of 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 fission and fusion 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.

Technology for people
DTU develops technology for people. With our international elite research and study programmes, we are helping to create a better world and to solve the global challenges formulated in the UN’s 17 Sustainable Development Goals. Hans Christian Ørsted founded DTU in 1829 with a clear mission to develop and create value using science and engineering to benefit society. That mission lives on today. DTU has 13,500 students and 6,000 employees. We work in an international atmosphere and have an inclusive, evolving, and informal working environment. DTU has campuses in all parts of Denmark and in Greenland, and we collaborate with the best universities around the world.
