Biography
My current research interests and activities are mainly related to both numerical and experimental research on heat pumps and refrigeration systems. The specific research topics include cycle modelling and thermodynamics, refrigerants, heat recovery, turbomachinery (especially centrifugal machines), real gas modelling and CFD.
During my research career I have gained solid expertise in numerical and experimental work related to types of thermal energy cycles including heat pumps, waste heat recovery systems, ORC, gas turbines, steam turbines, and energy systems adopting supercritical fluid states.

During my research career I have gained solid expertise in numerical and experimental work related to types of thermal energy cycles including heat pumps, waste heat recovery systems, gas turbines, steam turbines, and energy systems adopting supercritical fluid states.
One of the major focus areas during my early stage research career has been organic Rankine cycles (ORC). This technology is capable to convert waste heat into electricity. ORC process is based on the working principle of conventional steam Rankine process, but an organic working medium is adopted in the system.
