As a researcher his primary focus is on the development of energy systems suitable for the power generation from low- and medium-temperature heat sources, which includes solar, biomass, geothermal and waste heat. This encompasses system design, simulation and optimisation, working-fluid selection and component design and development, with significant focus on turbomachinery components.

Specific areas of interest include:
- Two-phase expansion in turbomachinery
- Modelling and optimisation of thermal-power systems
- Turbomachinery design and optimisation
- Characterising the behaviour of non-ideal fluid behaviour (NICFD)
