Lise Friis Christensen

Lise Friis Christensen is a Postdoctoral Researcher at the Department of Biotechnology and Biomedicine, Technical University of Denmark (DTU), affiliated with the Section for Synthetic Biology Biosynthetic Pathway Engineering and the DTU Microbes Initiative. Her research bridges microbial enzymology and sustainable food applications.

She earned her PhD from DTU in 2024 with the thesis "Extracellular proteases of lactic acid bacteria in targeted hydrolysis of plant proteins," supervised by Prof. Eric Banh-Thi Hansen and Paolo Marcatili.

Christensen's work centers on protease biochemistry and protein catabolism in lactic acid bacteria, with emphasis on plant protein hydrolysis for dairy alternatives and food fermentation. Her fingerprint highlights expertise in casein, vegetable proteins, and Lactococcus systems.

Analysis of her 2023-2025 publications reveals a cohesive trajectory: structural characterization of bacterial proteases (particularly cell-envelope types), development of enzymatic assays (e.g., FRET-based patatin detection), and practical applications in soy-based dairy alternatives through targeted proteolysis.

Her doctoral project (2019-2024) "Engineering targetable proteases with origins from lactic acids bacteria" focused on oligopeptide production and protein structure prediction. Current postdoctoral work continues this mission within DTU's microbial enzyme engineering framework.

Christensen operates within DTU's Synthetic Biology Biosynthetic Pathway Engineering section, contributing to the DTU Microbes Initiative's mission of developing microbial solutions for sustainable food systems through enzyme engineering and fermentation science.
