Meet the people who make up STEM Faculty.
Senior Lecturer In Electronic Engineering and Bionanotechnology
Dr Sotiria Psoma received her MSc and PhD from the Institute of BioScience and Technology of Cranfield University. Her MSc by Research was carried out in the field of biosensors and nanotechnology. The main focus of her doctoral thesis was the development of optical biosensors for clinical and environmental applications using enzymatic reactions and immobilisation techniques, fluorescence spectroscopy, bioelectronics and fibre optics. Sotiria has a first degree in Electronic Engineering from the Piraeus University of Applied Science in Athens, Greece.
For over 30 years, Dr Psoma has gained substantial experience in the development of optical biosensors, micro-nano-biosensors and bioengineering applications for healthcare. Before joining the Open University in September 2018, Dr Psoma worked as an Experienced Research Scientist at Cambridge Display Technology Limited, in the field of biosensors/sensors. During her career she participated in national and EU research projects with international collaborations and she held a number of senior research and teaching positions. She worked in the Engineering Department of the Rutherford Appleton Laboratory (Marie Curie Fellow), the Gray Cancer Research Institute at Mount Vernon Hospital/Northwood, the Department of Pharmaceutical Studies at the University of Nottingham and the University of Western Macedonia in Greece.
Between 2011 and 2017, Dr Psoma held the honorary post of Visiting Professor in Nanotechnology/BioMEMS at EPFL (École Polytechnique Fédérale de Lausanne), School of Engineering, Institute of Microengineering in Switzerland and she closely collaborated with Professor Nico de Rooij in SAMLAB.
Sotiria is a member of the international Editorial Advisory Board of the Open Access Books ToolKit (OAPEN Foundation, Netherlands and Springer Nature Publishing).
Since 2021, Dr Psoma holds the position of Visiting Academic at the School of Aerospace, Transport and Manufacturing of Cranfield University.
The research interests of Dr Psoma are focused on harnessing the power of engineering and nanotechnology for developing low-cost, reliable, highly stable optical biosensors for healthcare applications. This is part of a multidisciplinary research effort aimed at exploring and developing aptamers, biocompatible materials and polymers, novel immobilisation techniques, microfluidics and bioelectronics for the construction of smart micro-biosensors towards personalised medicine.
The five major strands of Dr Psoma’s research portfolio are:
1. Basic understanding of the interface of biological materials with transducers in biosensor technology and immobilisation techniques
2. Aptamer technology in combination with Nanotechnology for biosensor applications
3. Development of 3D models with integrated fluidics and OLED/OPD electronics
4. Utilisation of fluorescence spectroscopy in optical biosensor field
5. Continuous monitoring and multi-analyte portable devices for diabetes management and healthcare applications
6. Computational analysis and design of microchambers and microfluidics for biosensor applications
7. Energy harvesting from the human body for self-powered biosensors
Sotiria is the founder of the European Wearables and Biosensing Network with aim to foster innovation, collaboration and synergy across diverse fields. The Network mission is to bring together diverse stakeholders including academic research institutions, RTOs, healthcare profesionals, patient associations, industry and policy makers, empowering them to shape the future of wearable and biosensing technology.

Dr Psoma is Chair of COST Action CA25148: Nanobiosensor Technology for Next-Generation Wearables: Towards Personalized Healthcare (WEARSENSNET), a European network dedicated to advancing wearable nanobiosensor technologies for real-time, non-invasive healthcare monitoring. The four-year project (2026–2030) was approved by COST in May 2026.
The Action brings together experts from academia, industry, healthcare, and policy to address key challenges in wearable biosensing, including sensitivity, system integration, multiplexed biomarker detection, and data analytics. Through WEARSENSNET, Dr Psoma leads a multidisciplinary community focused on accelerating innovation in personalized healthcare, supporting research collaboration, knowledge exchange, and the development of next-generation wearable diagnostic technologies. The Action also places a strong emphasis on training and empowering Early Career Researchers, helping to strengthen European leadership in wearable biosensors and digital health.
