Niamh is using her Chemistry background in the development of a microfluidic paper-based analytcial device for the detection of nutrients such as nitrite. Her interdisciplinary research integrates chemistry, mechanical engineering and oceanography, utilising metal organic frameworks as a sensing material and building an effective device.
Nutrient molecules such as nitrate are the foundations of the naturally occurring life cycles within the oceans and seas. However, an excess of these nutrients resulting from human activity (such as from sewage discharge) result in the formation of toxic algal blooms that suffocate and pollute the coastal waters. Therefore, measuring the concentration of the nutrients are essential for the understanding and safeguarding against the harmful pollution.
Ordinarily, nutrient levels are recorded by transporting a sample to a lab for analysis, where costs and availability of transport limits the number and frequency of these measurements. Performing in-situ testing using devices based on lateral flow systems would offer a cheaper alternative for the widespread testing.
As a sensing element, metal organic frameworks (MOFs) will be utilised as a porous, easy to synthesise solid that can be rationally designed as a receptor for specific molecules, like the target nutrients.
The MOF-based lateral flow device should be user-friendly so that they can be used by non-experts and should be capable of detecting nutrients at typical environmental concentrations.
Niamh graduated from UoS with First Class Honours in MCHEM Chemistry with 6 month placement in June 2022. After taking a year in hospitality, Niamh has returned to the University of Southampton to pursue a PhD, combining her chemistry knowledge with mechanical engineering and oceanography for developing microfluidic paper-based analytical devices.
Niamh's work has been recognised with two poster competition awards, highlighting the impact and multidisciplinary nature of her research.
In addition to her research, Niamh is actively involved in teaching within the chemistry department. She demonstrates in the undergraduate teaching laboratories for first and second year chemistry students. She also teaches chemistry theory in a workshop designed for those undertaking a Science Foundation Year.
Outside of academics, Niamh is an active member of the Southampton Spitfires, the University Ice Hockey Club. Previously, she has held a social secretary role, but is now President for the club in the year 2025/2026.
