About me
BEng in Telecommunication in 1985, MEng in Biomedical Engineering in 1995 and Ph D in Biomedical Engineering in 1999. A senior member of IEEE, an associate editor of the Elsevier "Measurement" journal with academic (Tsinghua Univ in China, Imperial College London) and industrial (Sharp laboratories of Europe) research experience. As the first author published over 20 peer-reviewed journal papers, a patent, and a book chapter.
Having experience in biomedical circuits and systems design in both component and transistor levels for biosensor interfacing, medical imaging data acquisition (electrical impedance tomography (EIT), ultrasound, single-photon counting X-ray), real-time traumatic brain injury recovering process evaluation, and implantable neural recordings for tiny insects:
Designed the minimum area low-power implantable mixed-signal neural recording die for blowfly (~200 uW/0.82 mm2 active area including 2 differential input neural amplifiers, a 2-1 multiplex, and a 10-bit, 100KSPS SAR ADC);
Designed electronic instrumentation for stem cell cultures won a “Live Demos” Prize in IEEE ISCAS (the flagship conference of IEEE circuits and systems society).
Also having experience in biomedical signal processing (auditory evoked brainstem responses (EEG signal) for vowel cognition, otoacoustic emission signal processing for newborn's hearing screening, noise reduction for improved measurements) and artificial intelligence (AI)/pattern recognition with neural networks for speaker identification. Micro-Electro-Mechanical Systems (MEMs) digital speaker (flat speaker), electrooculography (EoG) based gaze tracking for augmented reality, Telecommunication (telephone switching) and wireless sensor networks / Internet of things (IoT: powering IoT sensor nodes with indoor photovoltaic (PV) energy harvesting).
Joined UWE in 2016 as a senior lecturer teaching electronics and as the head of instrumentation at the Institute of Biosensing Technology undertaking research work in passive bioimpedence sensing for wearable biosensors, zero-power human-computer interactions, passive locating for home management of dementia patients (healthy ageing), and micro/nanoelectronics for motion insensitive contactless electrodes in digital health.
