Sef Heijnen - Square

"Online education challenges me to focus on principles. It stimulates students to learn to use principles and not reproduce examples. In (bio)processes design one only needs 4 principles (conservation, 2nd Law, rates, balances). Four principles are more informative than 1000 examples."

Sef Heijnen has 15 years of experience working in fermentation industry (1973 – 1988) and since 1988 has been full professor and group leader of Cell Systems Engineering at the Department of Biotechnology at TU Delft. He has supervised more than 50 PhD thesises and has published over 300 papers (h ≈ 60). His research is focused on metabolic engineering and systems biology for application in industrial microbial processes.

He teaches BSc- and MSc-level courses, including metabolic engineering, systems biology, thermodynamics and bioprocess design. In addition, he teaches advanced courses on microbial physiology, environmental biotechnology and fermentation technology for industrial partners and PhD students.

In 2003, he was elected TU Delft's best lecturer of the year. He is member of the Royal Netherlands Academy of Arts and Sciences (KNAW) and advisor to DSM, Amyris, Genomatica, Lucite and Corbion.
