My research focuses on aerosol emissions from combustion and industrial processes, their environmental effects and emission control techniques. The research topics cover the effects of combustion technologies and fuels on emission chemical and physical properties, and emission transformation and environmental impacts in the atmosphere. The development of novel exhaust gas after-treatment technologies and circular economy aspects of combustion processes are as well part of the research activities. My research group collaborates extensively with industry and with national and international research groups.
