Reasearch / work
My research deals with development of robust bioprocesses for production of biobased fuels, chemicals, and microbial cultures. The focus is on the interplay between process conditions and microbial physiology. The main application is advanced fed-batch methodology for bioethanol production from lignocellulosic raw materials, using dynamic mathematical models and physiologically based control as tools. The methods are also applied to biobased production of chemicals, such as lactic acid using thermophilic bacteria. I also collaborate with industry to investigate how microbial production processes can be designed and modulated to produce robust starter cultures (lactic acid bacteria) and probiotics (bifidobacteria). My research leads to reduced emissions of carbon dioxide through better utilization of agricultural and forestry residues for production of important renewable biofuels and chemicals. Within the Chalmers Master program in Biotechnology, I am responsible for the courses KBT090 Industrial Biotechnology and BBT010 Ethics in biotechnology.
