Master Projects

Immediate MS projects are available in Microtechnique and Bioengineering for the 2022-2023  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 for Chiral Metasurfaces

Description: Metasurfaces offer the possibility for manipulating light at the nanoscale. This disruptive technology can be used for a wide field of applications. However, challenges in designing the best possible metasurfaces persist and cannot keep up with the demand for advanced optical functionality. This project aims to tackle the optical design challenge of metasurfaces for chiral sensing. We want to use modern machine learning approaches with high quality optical simulations to find the metasurfaces suited best to characterize chiral molecules such as DNA, drugs or proteins with high accuracy and low sample volume.

Who we are looking for: We are looking for a motivated student curious to explore the limits of inverse metasurface design towards the new regime of chiral sensing. Since this endeavor is mainly of computational and theoretical nature, we are looking for a student with high affinity towards programming and prior experience with machine learning.

What we offer: We offer a deep insight into photonics, optics and cutting-edge nanotechnology. Throughout the project, you will learn essential skills related to optical design, metasurfaces, and deepen your understanding of machine learning approaches. High performance equipment with up-to-date GPU.
Additionally, we appreciate a friendly atmosphere and offer a pleasant and stimulating working environment.

Single cell biosensing

Duration: Six to nine months


In this interdisciplinary project, we integrate our on-chip sensor technologies with micro/nanofluidic systems for efficient analyte trapping and manipulation. Particularly, we leverage a microfluidic live cell culture platform and nanophotonic biosensors, which enables real-time cell analysis in a label-free manner under physiological conditions. The main goal is to build a versatile and robust technique for high-throughput and multiparametric single-cell secretion analysis that can pave the way for a wide range of biomedical applications. Basic knowledge in biology, optics &amp; microscopy, and familiarity with the micro/nanofabrication processes is required. Previous experience with cleanroom work and/or handling live cells is a plus.
