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. As the first author published over 20 peer-reviewed journal papers and a book chapter (see Publication_List).

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 size 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’07 (ISCAS is the flagship conference of IEEE circuits and systems society).

Also having experience in biomedical signal processing (auditory brainstem responses (EEG signal), otoacoustic emission signal, noise reduction for improved measurements) and pattern recognition with neural networks for speaker identification. Micro-Electro-Mechanical Systems (MEMs) digital speaker (flat speaker), electrooculography (EoG) based dry electrode 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, zero-power communication for IoT sensor nodes such as in body sensor networks).
