Carl Johan Franzén

Associate Professor,
Biology and Biological Engineering, Industrial Biotechnology

Carl Johan Franzén is Associate Professor in Bioreaction Engineering. He is Chair of the BIO Department Faculty Assembly, member of the equality committee and the undergraduate education committee at the BIO department, and Student ombud at Chalmers.

His 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. He also collaborates with industry to investigate how microbial production processes can be designed and modulated to produce robust starter cultures (lactic acid bacteria) and probiotics (bifidobacteria).

Carl Johan Franzén’s teaching is focused on student-centered learning activities within biobased production as well as ethics in research and engineering within biotechnology. He is course responsible, examiner, and one of two main lecturers in the MSc courses KBT090 Industrial Biotechnology and BBT010 Ethics in biotechnology. He is responsible for the laboratory course and teaches simulation exercises and assignments in the BSc course KKR091 Bioreaction Engineering.
He contributes to the international PhD course ”Industrial Biotechnology for lignocellulose based processes” which is given by the Industrial biotechnology division every second year.

He also has experience with lectures and computer exercises in e.g. regression analysis, response surface methodology, metabolic flux analysis, and metabolic engineering.

During 2001-2016 he was Head of Programme for the integrated MScEng program in Bioengineering (TKBIO), with responsibility for economy, pedagogical development, quality assessment and strategic development of the program. This also included responsibility for the three-year BSc degree in Bioengineering and for the two-year international master program in Biotechnology (MPBIO) leading to the MSc degree in Bioengineering.
