Henrik Siegumfeldt

Henrik Siegumfeldt is an Associate Professor in the Department of Food Science at the Faculty of Science, University of Copenhagen. His research focuses on both positive and negative aspects of food microbiology, with particular expertise in fermentation processes, spoilage mechanisms, and pathogenicity of microorganisms. He teaches general food microbiology and contributes to specialized courses in Brewing Science and Dairy Microbiology.

Dr. Siegumfeldt's educational background includes a Ph.D. (defended May 2000) with the thesis "The dynamics of pHi regulation in lactic acid bacteria" and an MSc (defended October 1997) with the thesis "Physiological studies of Saccharomyces cerevisiae during fermentation of beer".

His research interests span multiple areas of food microbiology, with particular emphasis on bioimaging and single cell studies of microorganisms in food matrices. He has developed expertise in fluorescence microscopy techniques to study bacteria in dairy products, single cell growth dynamics, rapid detection methods for physiological changes, and adhesion dynamics of microbial cells. His work bridges fundamental microbiology with practical applications in food safety and quality.

Analysis of his recent publications reveals a strong focus on microbial behavior in food systems, particularly examining bacteria in fermented products like beer, wine, and dairy. His research integrates advanced imaging techniques with microbial physiology to address food safety challenges and improve fermentation processes. Key themes include stress responses of foodborne microorganisms, microbial interactions in complex food matrices, and development of novel monitoring tools for industrial applications.

Administratively, Dr. Siegumfeldt serves as Head of Studies for the MSc in Food Science and Technology since 2008, and previously held the same position for BSc programs (2008-2015) and was Head of the Food Microbiology Section (2009-2010). He has supervised 4 PhD students (3 completed, 1 active) and chaired 17 assessment committees.

His research leadership includes management of 5 scientific projects with 9.4 million DKK in external funding. He has an extensive publication record with 71 research outputs including 48 journal articles, and is actively engaged in knowledge dissemination through 22 activities and 12 media contributions focused on food safety and brewing science.
