Dr Walid Issa received his BSc and MSc in Electrical Engineering from the Islamic University of Gaza, Palestine (First Class Honours) in 2007 and 2010 respectively. In 2015, he received his PhD in Renewable Energy from University of Exeter. Walid joined Sheffield Hallam in September 2016 as a Lecturer in Electrical and Electronic Engineering. His main research interests include power electronics, digital control, DC/AC and DC/DC converters and microgrids.
Over 8 years of part-time and full-time teaching experience in higher education beside over 6 million views for his online teaching-based courses via YouTube, Walid presents his teaching enthusiasm and passion.
He worked as a teaching assistant and as a lecturer from Sep 2007 to Sep 2010 at the Islamic University of Gaza (IUG) and the University College of Applied Science (UCAS) delivering different modules such as signals and systems, control systems, digital logic design, basic electronics, robotics and microcontrollers programming. He also supervised undergraduate dissertation projects.
In 2011, he has been awarded a PhD studentship from the University of Exeter to pursue his study in Renewable Energy.
During his PhD, Walid developed the first practical setup, at Exeter University, of a microgrid based on dSpace 1103.
Before finishing his PhD, in 2014, he was appointed as a research associate leading a research within a £1 million EPSRC-funded project (RESCUES) to produce efficient community energy solutions. His role included involved practical design and implementation of a large scale Microgrid Lab prototype using real time controllers and simulators (OPAL-RT and dSpace 1103) including
- hardware-in-the-loop testing
- numerical modelling by Matlab/Simulink
- designing electronic control system for a 5kW solar tracker at Penryn campus
In August 2016, Walid was awarded Associate Fellowship of Higher Education Academy (AFHEA).
Since September 2016, Walid has been a Lecturer in Electrical and Electronic Engineering with Sheffield Hallam. His teaching activity covers several modules for level 4, 6 and 7 (undergraduate and postgraduate students) in Electronics, machines and power systems. Walid is also supervising several final year project students and a few placement students.
