Postdoc in Photonic Nanostructures for Biosensing Applications – DTU Electro
Kgs. Lyngby, Denmark
Job Description

Are you passionate about working on an interdisciplinary project, developing a new platform for fast and accurate pathogens detection? 
The Department of Electrical and Photonics Engineering (DTU Electro) at Technical University of Denmark is actively seeking for a highly motivated and skilled postdoctoral researcher to join the “Quantum Photonics in Low-Dimensional System” group. This project is funded by a Novo Nordisk Foundation Exploratory Interdisciplinary Synergy Programme and led by Associate Professor Sanshui Xiao, in collaboration with groups of Yi Sun (DTU Health Tech) and Jan Gorodkin (University of Copenhagen). The primary objective is to use recent advances in bioinformatics, molecular diagnostics (including a novel non-enzymatic amplification technology (NISDA) recently published [1] and patented), and photonic engineering to develop a lab-on-chip platform for rapid and accurate pathogens detection for massively parallel multiplex screening. 
You will work on the concept of the bound states in the continuum [2,3] in optical nanostructures to develop a new photonic device to enhance fluorescence emission of dye molecules and eventually to improve the detection sensitivity. The photonic device will then be integrated with lab-on-chip devices provided from DTU Health Tech. This research will be conducted within the framework of an exciting interdisciplinary project, providing you with unique opportunities for collaboration.
Responsibilities and qualifications
As a postdoc, your main responsibility will be to design, fabricate and characterize a nanostructure platform to enhance the sensitivity of the optical sensor for pathogens detection. More specifically, this will include:

• Developing a new nanophotonic platform to enhance fluorescence emission of dye molecules using COMSOL (based on finite element method, FEM);
• Nanofabrication of a proposed device using different thin film deposition techniques, photo- and/or E-beam lithography, and reactive ion etching. Visual inspection of fabricated structures using SEM, AFM;
• Optical characterization of obtained devices using reflectance and PL measurements;
• Publish research findings in top-tier scientific journals and present at international conferences;
• Interest in the supervision and mentoring of students;
• Participate in project-related activities and meetings;

You will benefit from the DTU clean room facilities. You are expected to have an excellent understanding of nanophotonics, optical spectroscopy and optical biosensing.  You can work independently and communicate efficiently with a team of experts in the field. 
As a formal qualification, you must hold a PhD degree (or equivalent). 
We offer
DTU is a leading technical university globally recognized for the excellence of its research, education, innovation and scientific advice. We offer a rewarding and challenging job in an international environment. We strive for academic excellence in an environment characterized by collegial respect and academic freedom tempered by responsibility. 
Salary and terms of employment 
The appointment will be based on the collective agreement with the Danish Confederation of Professional Associations. The allowance will be agreed upon with the relevant union. The period of employment is 14 months.
