Third-cycle subject: Applied Physics      

The project will be performed in the Exp Biomolecular Physics group, dept Appl Physics. The research focus of the group is on fluorescence-based ultrasensitive and super-resolution imaging and spectroscopy techniques for molecular and cellular studies, method development as well as applications in fundamental biophysics and towards clinical applications. Within this framework the aim of this project is to develop a new method based on fluorescence blinking, allowing biomedically relevant cellular conditions to be monitored in cells. The project is highly interdisciplinary, and spans both experimental (optics/photonics, spectroscopy/imaging, chemistry, cell and molecular biology), as well as theoretical work (modelling/data acquisition/programming). The project will also include collaboration with biomedical research groups.

Supervision: Prof Jerker Widengren is proposed to supervise the doctoral student. Decisions are made on admission

Admission requirements

To be admitted to postgraduate education (Chapter 7, 39 § Swedish Higher Education Ordinance), the applicant must have basic eligibility in accordance with either of the following:

• passed a second cycle degree (for example a master’s degree), or
• completed course requirements of at least 240 higher education credits, of which at least 60 second-cycle higher education credits, or
• acquired, in some other way within or outside the country, substantially equivalent knowledge

Moreover, the applicant should have:

• A MSc degree in Engineering Physics, Biomedical physics or related subject
• Hands-on experience from advanced fluorescence spectroscopy/imaging
• Good programming skills (e.g. Python, Matlab)
• Strong motivation and interest in biomolecular physics and interdisciplinary research

In addition to the above, there is also a mandatory requirement for English equivalent to English B/6.

Selection

In order to succeed as a doctoral student at KTH you need to be goal oriented and persevering in your work. During the selection process, candidates will be assessed upon their ability to:

• independently pursue his or her work
• collaborate with others,
• have a professional approach and
• analyze and work with complex issues.
• Good skills in English (spoken / written) as we work in an international environment

After the qualification requirements, great emphasis will be placed on personal skills. 

Target degree: Doctoral degree

Information regarding admission and employment

Only those admitted to postgraduate education may be employed as a doctoral student. The total length of employment may not be longer than what corresponds to full-time doctoral education in four years’ time. An employed doctoral student can, to a limited extent (maximum 20%), perform certain tasks within their role, e.g. training and administration. A new position as a doctoral student is for a maximum of one year, and then the employment may be renewed for a maximum of two years at a time. In the case of studies that are to be completed with a licentiate degree, the total period of employment may not be longer than what corresponds to full-time doctoral education for two years.

As a doctoral student, you are entitled to a workplace with many employee benefits and monthly salary according to KTH’s Doctoral student salary agreement. Read more about Doctoral studies (PhD) | KTH | Sweden.
