He has more than 25 years research experience in the area of solid state/materials chemistry, ranging from battery materials to solid oxide fuel cells. In these areas he has published more than 200 papers in scientific journals, and has written more than 15 invited review articles. His present research is focusing mainly on the development of novel ionic and mixed conductors for energy storage and conversion applications (e.g. Li/Na ion batteries and solid oxide fuel cells), including the use of novel doping strategies to stabilize new systems/improve materials performance.

He is also active in promoting research into new energy technologies to the general public, and in schools.
