Cecilia Geijer

Associate Professor at Industrial Biotechnology

Cecilia Geijer works as an Associate Professor at the Division of Industrial Biotechnology. She has a PhD in Microbiology from the University of Gothenburg, Sweden, and has been employed at Chalmers since 2013. In addition to research and teaching, Cecilia also serves as a Senior Strategic Advisor for Chalmers' Area of Advance Energy and as a member of Chalmers' Faculty Appointment committee. She is also a co-founder of a start-up company that develops yeast strains and bioprocesses for production of food ingredients.

Cecilia’s research spans between curiosity-driven fundamental research and challenge-driven development of new biotechnological applications. Specifically, she is interested in exploring yeast biodiversity with the aim to uncover unique mechanisms, genes, and enzymes for assimilation of different carbon sources, and make use of these discoveries to develop novel microbial cell factories and bioproduction processes. Through collaboration, Cecilia’s research group also performs bioinformatic and comparative genomic analyses and develops novel biomaterials. Research funding includes grants from Formas, Novo Nordisk foundation, Vinnova and H2020.

Cecilia is the examinator and lecturer in the course KBT016 Biochemistry and Biotechnology, and gives lectures in KLI021 Food Microbiology, BBT065 Industrial Biotechnology and the PhD student course Industrial Biotechnology for Lignocellulose Based processes. She is also an examinator in BBTX11 Bachelor projects in Biology and Biological engineering.
