I'm a Professor (tenured) of Fluid Mechanics and Head of Research group of Fluid Dynamics in the School of Energy Systems in LUT University, Finland. Previously, I was an Academy Research Fellow (from 2011 to 2016). Generally, my research interests are related to energy conversion cycles and devices such as Organic Rankine Cycles (ORC), Supercritical Brayton Cycles, heat pumps, steam turbines, centrifugal compressors, and radial turbines. I have focused on the modelling of condensing flows and the effect of turbulence on it. The research consist of the numerical and experimental work and the main aim is to understand and diminish losses occurring in the processes and components and enable their use e.g. in high temperature heat pumps and hydrogen compression. I'm currently leading research projects related to supercritical CO2 flows and heat transfer, high temperature heat pumps and organic Rankine cycles.
