I joined Energy and Power Group (EPG) as a postdoctoral research assistant in April 2016 working on Grid Scale Energy Storage Systems with Dr Dan Rogers and Prof Dave Howey. My current research is State-of-Health (SoH) estimation of Li-ion batteries specifically Lithium Titanate LTO. I am also looking into State-of-Charge estimation of Li-ion batteries for Grid Scale applications.
Before joining EPG, I did a PhD in Power Electronics funded by the EPSRC at the Power Electronics, Machines and Control (PEMC) Group at the University of Nottingham supervised by Prof Mark Johnson. My thesis titeled "In-service estimation of state of health of power modules" investigated condition monitoring for power semiconductor devices, specifically Insulated Gate Bipolar Transistors (IGBTs) modules. I investigated the correlation between power modules thermo-mechanical degradation mechanisms (wire-bond lift-off and solder fatigue) and measureable parameters that can be used as failure indicators. I developed measurement circuits to obtain on-state voltage VCE(ON) and gate threshold voltage VG(th) of IGBTs during normal converter operation. I also developed algorithms to estimate junction temperature of IGBT devices, the change in thermal resistance and the change in electrical resistance of IGBT modules.
In 2011, I worked as a Research Assistant at Rolls-Royce University Technology Centre (UTC) at the University of Sheffield where I aslo did an MSc in Control Systems. I got my BSc in Electronics and Computer Engineering from the University of Aleppo in Syria in 2009.
