About Torbjörn Bengtsson

Torbjörn Bengtsson is a Professor in Medical cell biology at Department of Medical sciences, Örebro University. He defended his thesis in 1990 at the Deparment of Medical microbiology, Linköping University. The thesis was about the regulation and importance of the cytoskeleton in neutrophil granulocytes and inflammatory processes. In 1995 Torbjörn was appointed as docent (Associate Professor) in Medical microbiology and 2003 he became professor in Inflammatory research at Linköping university.

Torbjörn Bengtsson´s main research focus is inflammatory and immune processes of host-microbe interaction. How infections cause diseases that are not normally classified as infectious diseases has been of interest for a long time, for example how bacteria-platelet interaction contributes to atherosclerosis. Together with a competent and dynamic research group, the research today focuses primarily on understanding the pathogenesis of periodontitis and its association with cardiovascular disease. In collaboration with basic and clinical researchers at Linköping and Malmö University and several industrial partners, the group is developing novel tools, based and plastic antibodies and nanoplasmonic sensors, for diagnosis of infectious diseases. Development of alternatives to antibiotics, anti-bacterial peptides called bacteriocins, in prevention and treatment of infections is another goal in the research. Bengtsson has authored more than 80 scientific articles and has been main supervisor for 13 PhD students, please see below.

During more than three decades Torbjörn Bengtsson has taught and had responsibility for courses in biology, biomedicine and medicine, especially in the subjects of cell biology and microbiology. For five years he was head of the Biomedical research school at Linköping University. Today Torbjörn is responsible for the two first semesters of the Medical School at Örebro University.
