Allmänt

Degrees in energy engineering and inorganic- (high temperture) chemistry. PhD in inorganic- (high temperature) chemistry (Umeå University) and Associate Professor (Docent) in thermo-chemical energy conversion (Umeå University). More than twenty years’ experience of R&D work in the area of thermo-chemical biomass conversion both at the Division of Energy Science at Luleå University of Technology (Chaired Prof 2007- ), the Department of Inorganic Chemistry/Energy Technology and Thermal Process Chemistry at Umeå University (Assistant Professor 2003-2006, Senior Lecturer 2003, Adj. Senior Lecturer 2002-2003, Ph D student 1995-1999, Project Assistant 1993-1994), the Energy Technology Center in Piteå (Research Leader 2006, Laboratory Manager/Senior Scientist 1999-2003, Development Manager 1997-1998) and in my own company Energiteknik i Norr (1997-2001). Extensive and close collaboration with industry and institutes, especially LKAB, Skellefteå Kraft AB, Vattenfall, Andritz, Sibelco, Bioenergy 2020+, RISE-ETC, Swerea-MEFOS, RISE-SP, VTT, Sintef and local, regional and national small to medium-sized enterprises.

Member or previous member of several different program and company boards (Energy technology centre in Piteå, SP Energy Technology Center AB, RISE Energy Technology Center, Swedish centre for biomass gasification, Black liquor gasification program, Etanol Pilot i Sverige AB, f3) and steering groups and evaluation panels (Bio4Energy, Hjalmar Lundbohm Research Center for mining and metallurgy, Swedish research council - Infrastructure for research on the earth and its near surroundings, Swedish research council - Advisory Group C linked to the research council for infrastructures: High technology laboratories for Subatomic Physics, Materials Science and Life Sciences, Bioenergy 2020+:s (an Austrian bioenergy inst.) International Scientific Advisory Board, Swedish thermal foundation).

Presently (since 2007), chaired Professor in Energy Engineering and Head of Division, Division of Energy Science at Luleå University of Technology.

Forskningsområden
