 The research will be carried out as a collaboration between the research group at the University of Gothenburg lead by Mattias Goksör and Caroline Adiels, and Victor Torres Company at the Calmers University of Technology. The groups focus on optical manipulation, microfluidic and imaging for applications in biological physics, and laser frequency combs, integrated optics and optical communications respectively.

Job assignments

We seek applicants for one PhD positions at the Physics Department of the University of Gothenburg. The successful candidate will be trained in experimental and computational optics, statistical physics and machine learning. Previous experience with experimental and computational methods in these fields will be considered a plus.

The goal of the research project is to use two phase-coherent frequency combs in order to implement a new linear microscopy technique. The technique shall offer diffraction-limited spatial resolution and sub-100 ns temporal resolution, initially using well-established electro-optic combs operating in the 1.5-µm band. The microscopy technology will be implemented for single-cell applications by combining the microscope with microfluidics.


To be eligible for third-cycle studies, the applicant must meet both the general and specific entry requirements:

A person meets the general entry requirements for third-cycle courses and study programmes if he or she:
1. has been awarded a second-cycle qualification,
2. has satisfied the requirements for courses comprising at least 240 credits of which at least 60 credits were awarded in the second-cycle, or
3. has acquired substantially equivalent knowledge in some other way in Sweden or abroad.

To meet the specific entry requirements for third-cycle studies, applicants must:
1.  have a second-cycle (advanced-level) degree in a relevant* subject area in the natural sciences, or
2. have completed studies for at least 60 higher education credits at a second-cycle level in relevant subject areas in the natural sciences, or
3. have completed a corresponding programme of relevance to the planned third-cycle programme, in Sweden or in another country, or have equivalent qualifications.

*Relevant for the planned third-cycle education

The specific entry requirements also include an acceptable command of spoken and written English. Guidelines for assessing English proficiency may include a minimum score of 550 on the TOEFL test (or 213 on the TOEFL-CBT, or 79 on the TOEFL-iBT).
