PhD: Optical Nanoscopy at Cryogenic Temperatures

Department/faculty: Applied Sciences
Level: Master degree
Working hours: 38 hours per week
Contract: 4 years
Salary: €2222 to €2840

Applied Sciences

The Faculty of Applied Sciences is the largest faculty of TU Delft, with around 550 scientists, a support staff of 250 and 1,800 students. The faculty conducts fundamental, application-oriented research and offers scientific education at the bachelor, master and doctoral levels. The faculty is active in the fields of Life and Health Science & Technology, Nanoscience, Chemical Engineering, Radiation Science & Technology, and Applied Physics.

The position is in the Department of Imaging Physics of the Faculty of Applied Sciences. This department performs cutting-edge research spanning the range from understanding the basic principles underlying imaging technology to automated image analysis.

The Quantitative Imaging (QI) group performs fundamental and applied research in sensing (imaging systems), processing, analysis, and interpretation of multi-dimensional images. The research is applied in three multidisciplinary programmes: medical image processing, biomolecular imaging (light and electron microscopy), and industrial imaging. These programmes are conducted in close collaboration with partners in academia (including several university medical centres), industry, and governmental research institutes.

Job description

The researcher will work in a team of experimentalists and theorists who share the common goal of imaging at the nanometre scale. She/he will work at the interface of the team designing, performing experiments, and developing modelling for data analysis. In order to achieve very high spatial resolutions from single molecule emitters, the wavefront of the light must not be disturbed by optical aberrations. In reality, such aberrations are always present, but only at our targeted high resolution at cryogenic temperatures do they play a crucial role. Therefore, the candidate will develop adaptive optics instrumentation and algorithms to measure the wavefront distortion and subsequently correct the distortions. We will use spatial light modulators to shape the wavefront.

The research will be performed at the Department of Imaging Physics in the Faculty of Applied Sciences at Delft University of Technology.


The candidate must hold an MSc degree in Physics. The candidate should have a background in experimental physics using high-end technical equipment and should have a track record of measuring, analysing, and comparing data to model predictions. Experience with microscopy, optics, fluorescence, and/or simulation packages is beneficial but not required.

Conditions of employment

The TU Delft offers a customisable compensation package, a discount for health insurance and sport memberships, and a monthly work costs contribution. Flexible work schedules can be arranged. An International Children’s Centre offers child care and an international primary school. Dual Career Services offers support to accompanying partners. Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities.
As a PhD candidate you will be enrolled in the TU Delft Graduate School. The TU Delft Graduate School provides an inspiring research environment; an excellent team of supervisors, academic staff and a mentor; and a Doctoral Education Programme aimed at developing your transferable, discipline-related and research skills.
