Research groups and centres


Samsun Nahar obtained her MSc degree in Polymer Science from the University of Potsdam in 2007. She completed her PhD (2008-2012) in Food Process Engineering at ETH Zurich, Switzerland with thesis entitled ‘steady and unsteady flow characterization of non-Newtonian fluids in elastic tubes’ utilizing Ultrasonic Velocity Profiling (UVP) technique for the flow field investigation and computer tomography (CT) method for the corresponding tube shape analysis. Following her PhD, Dr Nahar worked as a Postdoctoral Research Fellow at the Dept. of Chemical and Process Engineering (University of Surrey, UK) on Engineering understanding of ‘swallowing process and food (non-Newtonian fluid) rheology’, and at National Centre of Excellence for Food Engineering (NCEFE, Sheffield Hallam University, UK), on ‘technology development for biopolymer extraction and characterization from agro/food waste’. In 2019, she joined as a Lecturer at the ThermoFluids subject group (Department of Engineering and Mathematics, Sheffield Hallam University). During this time, she was responsible for teaching and assessment duties for undergraduate & postgraduate programme, and final year project supervision.

In 2021, Dr Nahar joined the Perpetual Plastic for Food to Go (PPFTG) project team at the Wolfson School of Mechanical, Electrical and Manufacturing Engineering, Loughborough University, working as a Postdoctoral Research Associate (PDRA) to develop a standard cleaning process for reusable FTG plastic packaging. A UV fluorescence detection system will be utilized and validated against industrial standards leading to improving the reuse value of plastic packaging.
