Mariusz Filipowicz is an associate professor at the AGH University of Science and Technology, Faculty of Energy and Fuels, and the former head of the Department of Sustainable Energy Development, Krakow, Poland. Professor Filipowicz graduated with an M.Sc. in Technical Physics in 1991, obtained a Ph.D. in 1998, and completed his habilitation in 2010 in the field of nuclear physics—nuclear fusion catalyzed by negative muons. Between 1994 and 1995, he completed a postgraduate course in Energy and Environment: the Tempus Joint European Project (JEP) Postgraduate Course on Energy and Environment. Professor Filipowicz’s main research areas are related to renewable energy technologies (mainly biomass, solar, and wind energy applications), energy efficiency, and nuclear physics (nuclear fusion reactions in the range of ultra-low energy). Additionally, he is the leader of scientific projects at AGH, such as, "BioEcoMatic: Construction of small-to-medium capacity boilers for clean and efficient combustion of biomass for heating" and "BioORC: Construction of cogeneration system with small-to-medium size biomass boilers" with the support of KIC InnoEnergy.
