SPOREA - Key Persons
Alex Teng (also known as Hao-Jing Teng in publications) graduated from the University of Surrey with a BEng degree in Electronic Engineering in 2021. His interests lie in integrating electronics with textiles and wearables inspired by futuristic interpretations of technology.
As part of his final year project, Alex worked on streamlining blood pressure monitors by using PPG sensors instead of inflatable cuffs. He created a prototype that demonstrated a design that could be used for long term blood pressure monitoring that would be less obstructive to the user by using off-the-shelf components and materials. Alex has also worked on a number of projects combining his creative side with electronics, notably working with Junction Ltd to install lighting on large theatre sets and installing electronic components into costumes.
Alex is currently working on his PhD, project ALPACA, under the supervision of Dr Radu Sporea with the aim to fabricate multimodal transistors (MMT) using solution processing. Alex is also interested in teaching and is currently working as a Brilliant Club Tutor which aims to engage students with their curriculum in a new and interesting way through weekly tutorials.
Job Titles:
- Senior Lecturer ( Associate Professor
- Senior Lecturer in Semiconductor Devices, SMIEE MSID
Dr Radu Sporea is Senior Lecturer (Associate Professor) in Power Electronics and Semiconductor Devices at the Advanced Technology Institute (ATI), University of Surrey and holds an EPSRC Early Career Fellowship (2021-2026). Prior to this appointment he was Royal Academy of Engineering Academic Research Fellow (2011-2016), EPSRC PhD+ Fellow (2010-2011) and PhD researcher (2006 - 2010) in the same centre. Before joining Surrey, Radu has studied Computer Systems Engineering at "Politehnica" University, Bucharest, Romania, and has worked as a Design Engineer for Catalyst Semiconductor Romania, now part of ON Semiconductor, on ultra-low-power CMOS analog circuits. Current research in Radu's team focuses on three main topics: 1. Advanced semiconductor device design, including transistors with increased tolerance to fabrication variability, improved energy efficiency and high gain. 2. Large area sensors and sensor arrays for smart environments, focusing on multi-modal low-cost integration in commercial manufacturing platforms and mass-market products. 3. Paper-based electronics and physical-digital interaction
Job Titles:
- Member of the IEEE Electron Devices Society
- Student
Eva Bestelink graduated with a BEng in Electronic Engineering with Nanotechnology at the University of Surrey in 2018 and is currently a PhD student at Surrey's Advanced Technology Institute, where she is supervised by Dr Radu Sporea.
Eva's research is based on unconventional contact-controlled thin-film transistor architectures, such as the source-gated transistor (SGT) and the recently invented multimodal transistor (MMT), which she co-invented with Dr Sporea. Her research focuses on exploiting contact effects for performance/circuit optimisation and novel functionality and enjoys working alongside Dr Sporea's network of collaborators, developing devices in a variety of material systems (silicon, amorphous oxides, organics, perovskites).
Eva has a MSc in Neuroscience and is interested in nature/neuro inspired solutions, as well as sustainable high-throughput manufacturing in low-cost methods.
Aside from research activities, Eva is a student member of the IEEE Electron Devices Society and a Member of the IET, proudly promoting engineering through regular engagement with young, aspiring scientists via summer school outreach and placement programmes, as well as demonstrating to first year UG students in the EEE labs.
