Current research

My research with ARCHA involves the use of Bio-Impedance Analysis (BIA) to develop a device which tells an individual their body composition, mainly in terms of muscle, fat, bone and water content, although not limited to these tissues only. It is intended to be capable of determining the distribution of these tissues within the body with fair accuracy; this along with acquired information of weight, height and age input can give a fair picture of the current health state of the individual.  With information regarding the health state and afore mentioned factors the device would give essential healthy living advice to the individual and prompt when a physician is to be consulted.

Bio-Impedance Analysis involves passing low current electrical signals through the body and detecting them. As these pass through tissues of varied impedance they are attenuated and their characteristics like phase, are altered. These altered signals carry information on the various tissues in the body. With further enhancements, the applications of this technology are vast and since it is non-invasive and inexpensive its widespread use is highly feasible.

Research funding

  • Aston Research Centre for Healthy Ageing (ARCHA) studentship.

Projects handled

  • 2009 - Study, Analysis and Modelling of DC-DC boost converter
    Done as part of my MSc, the project involved modelling a boost converter from a control perspective and designing a feedback compensator which could compensate for line and load regulations of the converter.

  • 2008 – Fingerprint recognition system for mobile phones
    Done as part of my B.Eng, this project successfully implemented a fingerprint verification tool for use with mobile phones. The outcome was a system which allowed a user to use his phone only after his fingerprint was verified.
