The Braunschweig International Graduate School of Metrology together with the Technical Cooperation of PTB offer the opportunity for currently two PhD scholarships each year for students engaged in natural sciences or engineering. The funding is provided by the German Federal Ministry for Economic Cooperation and Development (BMZ) to support developing and emerging countries (please see full list of partner countries) in the field of quality infrastructure. Initially, funding will be granted for one year. Given that it typically takes three years to complete a doctoral thesis PTB will be committed to obtain a follow-up funding. The size of the grants is comparable to grants provided by the German Academic Exchange Service (DAAD). The scholarships will be located at TU Braunschweig.
An excellent academic record and fluent English are prerequisites; skills in the German language are welcome. The submission should include CV, transcripts of the most important documents of professional qualification and a letter of application. B-IGSM promotes the professional equality of women and men and is thus especially interested in applications from women. Disabled persons will be given priority if they have the same occupational aptitude. Any granting of a scholarship has to be approved by the International Office of TU Braunschweig taking into account the Promotionsordnung (PhD Regulations) of the respective faculty where the scholarship will be located.
Please note that any application needs to be submitted via the application portal of B-IGSM.
Integrated Wearable Biophotonic Sensor Systems for Point-Of-Care Medical Diagnosis
The development of novel sensor systems for Point-of-Care medical diagnosis has been becoming an active new area of nano-optoelectronics. In particular the integration of nanoscale optical devices (e.g., nano-light-emitting diodes (nanoLEDs) or laser diodes in the UV spectral range) opens up many new possibilities for biophotonics.
Wearable, multifunctional sensor technology would be highly desirable in many cases such as ambulatory monitoring and disorder observation in both clinical and home use. The aim of this project is to develop highly integrated, wearable optical sensing systems integrated with blood oxygen saturation, blood pressure or other measurements by using LEDs. This non-intrusive, non-invasive, robust and low-cost diagnostic tool can continuously deliver us information of our body condition, which will be further used as a basis for continuous ambulatory health monitoring.
As will become clear below, the measurement techniques for various health monitors (e.g., blood pressure and blood sugar levels) in a human depend on many cross-correlations and will be influenced by many parameters, which are not directly related to the measurement itself. Assessing the measurement uncertainties to evaluate the reliability of health monitoring data on the basis of a full metrological analysis therefore is a major ingredient of future point-of-care medical technology. Therefore, besides the development of optical health monitoring systems (i.e., including both hardware and software), the metrological aspects of health monitoring will be a major focus of this project. Novel monitoring systems will not only be developed, but also their measurement uncertainties will be determined quantitatively in order to build trustable health monitoring systems.
The Institute of Semiconductor Technology (IHT) at Technische Universität Braunschweig operates strong research programs on GaN optoelectronics and nanoelectronics, including GaN epitaxy, material analysis, LED development and optoelectronic systems, in close collaboration with industrial partners.
The project will be embedded in the excellent research environment at IHT, including the epitaxy competence center (ec2), operated in close collaboration with Osram Opto Semiconductors GmbH, as well as the Laboratroy of Emerging Nanometrology (LENA), a research center devoted to the development of nanometrology, in close collaboration with our core partner Physikalisch-Technische Bundesanstalt (PTB) Braunschweig.
