Competition Funded PhD Project (European/UK Students Only)
Sustainability and human wellbeing depend on resources from marine and freshwater systems, and to monitor how they are changing, a range of observations are needed. In situ measurements of physical water properties like temperature and salinity are almost trivial, but higher-level sensors that address biogeochemical properties, or even trophic levels, are often complicated, expensive or need expert operation. Therefore, there is a desperate need for instrumentation that can deliver in-situ, real time information from physics to biology in aquatic ecosystems supporting researchers, industry, policy makers and the public. A recent technological development of ours that could address this problem is the realisation of a passive “artificial tongue” device capable of detecting and classifying a myriad of complex chemical mixtures in real-time.
In this project, you will use this new class of nano-scale sensor in an aquatic environment for the first time. Through the development of a portable tongue device specifically tuned for aquatic field measurements you will aim to demonstrate a versatile, low- power, high-resolution optical sensor array capable of classifying and identifying a range of physical, biological and ecosystem indicators.
You will join an exciting multidisciplinary project team and will spent the first year in an optics lab at the University of Glasgow to characterise the optical performance via transmission/absorption spectrometry. The aim will be to start with relatively straight forward measurements like temperature before aiming to capture biogeochemical measurements like dissolved oxygen, total and dissolved carbon dioxide, nitrate, nitrite, ammonium and pH. This work involves training in fabrication techniques including; electron-beam lithography, metal-evaporation; scanning electron microscopy; and atomic-force microscopy. You will also be trained in transmission/absorption spectrometry to characterise the sensor’s optical performance. In subsequent years, you will test the instrument outside of the lab in more challenging environments and will work more closely with marine scientist in Glasgow and St Andrews testing the instrument in several environments and settings (research, survey, industry). You will test the long-term stability of the instrument and work through real-world examples of how the measurement of concurrent parameters can improve our understanding of small-scale processes in the marine environment. You will be trained in physical, optical and biological marine data collection and will develop skills in computer programming using Matlab.
This project is part of the Scottish Universities Partnership for Environmental Research (SUPER) Doctoral Training Partnership (DTP) and you will get additional interdisciplinary training through this partnership.
We are looking for a scientist with a good degree (BSc/MSci 2(1) or above, or MSc) in a relevant field, e.g. optics, engineering, physics, physical oceanography. Applicants with degrees in other subjects are invited to discuss their qualifications with the supervisors. A masters-level degree is an advantage.
