PhD Position

PhD Position – Dielectric metasurface devices and systems

Metasurface optics is a powerful platform for realizing next-generation biomedical sensing and imaging technologies. This multi-disciplinary project aims to develop novel all-dielectric metasurface devices and integrate them into ultra-compact systems for optical and infrared biosensing applications. The project will involve experimental nanophotonics with state-of-the-art equipment, nanofabrication in EPFL’s world-leading cleanroom facilities, smart data analysis and bioanalytical methods. The student will be able to not only work on cutting-edge research projects but also interact with world-leading industry companies for high-impact applications. Applicant’s experience in photonics, metasurface optics, nanofabrication, experimental and computational skills are preferred, but not required. We are looking for young and talented people to join our vibrant group.

Master Projects

Immediate MS projects are available in Microtechnique and Bioengineering for the 2019-2020  academic year. Projects are on the development of lab-on-a-chip nano-biosensors. The students will be exposed to nanophotonics, nanofabrication, microfluidics, cellular/molecular biology.

For students interested in Master projects or semester projects, the following projects are available to be performed in the summer or during academic semesters. Please send your questions, CV and your availability to the corresponding supervisor.

Machine learning and signal processing for nanoplasmonic biosensing

Recently, we have achieved successful integration of microfluidic live cell culture technique with the nanoplasmonic biosensor, which enables real-time cell analysis in a label-free manner under physiological conditions. In the meantime, we are developing high-end imaging techniques for high-throughput and multiplexed biosensing platform, to further implement it in broader biomedical applications (e.g. single cell analysis, screening for cell therapy). Therefore, it is essential to equip the platform with robust and reliable signal processing to realize ultra-sensitive biodetection.

This opportunity is suitable for an internship or a master’s project.

3D Nanofabrication

3D nano-structures are extremely attractive due to their unique interaction with light as well as their biomimetic properties. In this project, students will participate in hands-on development of high throughput, large scale 3D fabrication methods as well as the optical characterization of the structures for various applications. Techniques involved are: Micro-nano fabrication methods, metrology including SEM & AFM, optical characterization and spectral measurement. This project is available as Master or semester project based on student’s schedule.

Microfluidic protein detection with biosensors

In this interdisciplinary project, we design fabricate & integrate microfluidic platforms that will be used to detect proteins with our custom made biosensing technology. The platform will be used to collect real-time multiplexed data from biomolecules. The techniques involved are: microfabrication methods, soft-lithography, and microfluidic systems.

Nanoimprint lithography

Developing a low-cost fabrication technic empowers transferring technology from university to industry. This project is about moving from expensive and time-consuming ebeam lithography to nanoimprint lithography (NIL). Students will participate in the fabrication process as well as the optical characterization of the structures for various applications. Techniques involved are: Micro-nano fabrication methods, metrology including SEM & AFM, optical characterization and spectral measurement. This project is available as a Master or semester project based on student’s schedule.
