PhD Position - information-age microscopy / wavefront shaping

Biomedical Photonic Imaging - University of Twente

Dr. ir. I. M. Vellekoop –

PhD position – Information-age microscopy

Within the Biomedical Photonic Imaging research group of MIRA – the Institute for Biomedical Engineering and Technical Medicine we have a PhD position in the research area of complex wavefront shaping and computational imaging.

Job description

Complex wavefront shaping is a young and rapidly expanding research field. One of its aims is to obtain sharp images of objects hidden deep inside opaque scattering media. This exciting field combines aspects of scattering theory, computational imaging, adaptive optics and holography.

This project aims to develop a microscope that can image at unprecedented depths inside non-transparent biological tissue without loss of resolution. Important challenges include developing a better understanding of wave propagation in tissue through experiments, simulations, and theoretical analysis, as well as implementing algorithms for image reconstruction and for focusing light deep inside scattering tissue. Funding for this project was obtained from the European Research Council.

You will work on fundamental aspects of imaging in the presence of scattering. As a PhD student, you will develop image reconstruction algorithms, novel simulation strategies, and approaches for focusing light inside stochastic scattering media. You will work closely together with experimentalists to demonstrate these novel concepts in proof-of-concept optical experiments. Depending on your interests, you may also conduct optical experiments yourself.

Your profile

We are looking for a quick thinker with strong analytical skills. You should have a Master’s degree in Physics, Applied Mathematics, Electrical Engineering, or related field, as well as an affinity for mathematical problem solving. Advanced programming skills in e. g. MATLAB, Mathematica, Python or C++ are essential.

Information and application

For further information you can contact Ivo M. Vellekoop

Candidates are invited to upload their application, including a letter of motivation, CV, a transcript of MSc grades and names/contact information of 2 or more references to before December 1 2016. An interview and presentation will be part of the selection procedure. Candidates must motivate their interest and fitness for this particular project. Applications with non-specific motivation letters are not taken into consideration.

Our offer

We offer a very challenging project in an inspiring environment. The assignment is four years, the length of the PhD program in the Netherlands, with a go/no-go assessment at the end of the first year. The candidate is expected to finish the project with a PhD thesis and disseminate the results through patents (if applicable), publications in scientific peer-reviewed journals and present at international conferences.

In accordance with the Collective Labour Agreement for Dutch Universities, the gross monthly salary for a PhD increases from € 2.174,-- in the first year to € 2.779,-- gross per month in the final year, plus a holiday allowance (8%), an end-year bonus (8,3% of the annual salary) and a number of additional benefits. The University of Twente provides excellent campus facilities, and actively supports professional and personal development.

The organization

The University of Twente. We stand for life sciences and technology. High tech and human touch. Education and research that matter. New technology which drives change, innovation and progress in society. The University of Twente is the only campus university in the Netherlands; divided over six faculties we provide more than fifty educational programmes. The University of Twente has a strong focus on personal development and talented researchers are given scope for carrying out pioneering research.

Within the TNW Faculty (Faculty of Science & Technology) of the University of Twente some 700 staff members and 2000 students are involved in training and research on the interface of chemical technology, applied physics and biomedical technology. Fields of application include sustainable energy, process technology and materials science, nanotechnology and technical medicine. Research, which enjoys a high profile both at home and internationally, has been accommodated in the multidisciplinary research institutes MESA+ and MIRA. The faculty works together intensively with industrial partners and researchers in the Netherlands and abroad and conducts extensive research for external commissioning parties and funders.
