I am a Research Postgraduate under the supervision of Dr Christos Markides and Dr Klaus Hellgardt. I commenced my PhD in the Heat and Power Division of the Clean Energy Processes (CEP) Laboratory in December 2014. Prior to my PhD I was a Research Assistant in the CEP Laboratory, which I joined in January 2014 after graduating from RWTH Aachen University, Germany, where I did both, my undergraduate and master's courses. After receiving the Bachelor's degree in Mechanical Engineering, I enrolled in the Power Engineering master's course, which I have successfully finished in October 2013.
My PhD research topic is low grade heat conversion technologies. My research focuses on the modelling of novel engine concepts, e.g. thermofluidic oscillators, which are an innovative concept to convert heat into useful work. The main applications of my engines are the use of solar heat and waste heat recovery. The research is closely linked to other research topics within the CEP Laboratory, such as organic working fluid design and small scale expander design.
