Postdoc in Capacitive Micromachined Transducers

A postdoc position in Micromachined Ultrasonic Transducers is available in the MEMS-Applied Sensors group headed by Prof. Erik V. Thomsen, Department of Micro- and Nanotechnology, DTU Nanotech. The group is focused on developing miniature ultrasonic transducers for use in medical imaging. The group works on all aspects of transducer design, fabrication and characterization and with development of ultrasound probes.
Recent years have seen the development of capacitive micromachined ultrasonic transducers (CMUTs) based on silicon technology. Realizing such transducers requires array and process design. To enable medical imaging, the transducers are assembled into ultrasound probes. The research field is highly interdisciplinary, combining nano fabrication, acoustics, electronics and physics-based analysis.
Responsibilities and tasks
The research in this project is focused on CMUT transducers for 3D medical imaging with special emphasis on transducers for Super Resolution Imaging (SRI).
Super resolution imaging with ultrasound is a new groundbreaking methodology enabling a true leap in the diagnosis of cancer and diabetes. It currently attains a 10 micrometer resolution by using ultrasound tracking of contrast agents. This opens a whole new and exciting field for investigating human micro-vascular physiology and diagnostics. You will be part of a larger project which has the ambition of translating SRI from experimental 2D imaging of small, immobilized rodents to human clinical use in full 3D.  The project develops new silicon based probes, a new flexible scanner, imaging and motion estimation schemes, and conducts human trials on cancer patients. The developed equipment and methods makes it possible to introduce a new, inexpensive 3D imaging scheme on the market that is usable for SRI and 3D abdominal ultrasound imaging with a full 3D visualization of flow.
Your responsibility will be to design CMUT transducers for 3D ultrasound using tools such as COMSOL, MATLAB, Mathematica and PZFlex. You will also be responsible for development of ultrasound probes for medical imaging. This task is aimed at encapsulating the developed CMUTs into a fully functional ultrasound probe that can be directly coupled to an ultrasound scanner. Being in a research environment, you will of course contribute to our ongoing research and to the supervision of students.
The project is undertaken in close collaboration with DTU Electrical Engineering, Rigshospitalet and BK Ultrasound.
Candidates should have a PhD degree or equivalent.
To be a successful candidate for this project, you should have a PhD degree in physics or nanotechnology and have extensive experience working with cleanroom technologies (including thin film deposition, pattern generation, etching and material analysis) for the fabrication of capacitive micromachined ultrasonic transducers. It will be an advantage if you have experience in the design, fabrication and test of ultrasound probes, as this is one of the tasks in this project.
Furthermore, you should have experience in lumped element modelling and programming skills in tools like Matlab, Mathematica, PZFlex and COMSOL.
To fit in the research group, we expect that you:

    are driven by exploring boundariesenjoy working with complex topicsare motivated by both personal and team accomplishmentsthrive on collaboration and teamwork

You should furthermore be highly motivated, a teamplayer, ambitious, and have a high scientific standard.
