I started my work as a Ph.D. student in August 2010. I received my M.Sc. degree in engineering - biotechnology from the faculty of engineering at Lund University in June 2010. My master's thesis was performed at Novozymes A/S in Bagsværd, Denmark.
Research
My research is within the field of bioprocess control. The focus is on developing, improving and optimizing fermentation control strategies for fed-batch bioprocesses used in enzyme production.
