Leanid Laganenka

Dr. Leanid Laganenka serves as a Project Group Leader at the Max Planck Institute for Terrestrial Microbiology in Marburg, Germany, within the Department of Systems and Synthetic Microbiology. He established his independent research group in March 2025, focusing on bacterial communication mechanisms and their role in host-microbe interactions.

His educational background includes:

• Diploma in Molecular Biology, Belarusian State University (2014)
• PhD in Biology, Philipps University Marburg (2018)

Dr. Laganenka's research centers on bacterial interspecies signaling, particularly through the autoinducer-2 (AI-2) system. His work investigates how quorum sensing regulates bacterial behavior in Klebsiella pneumoniae, including interactions with host immune cells and environmental persistence. Using in vitro techniques (proteomics, flow cytometry, advanced imaging) and in vivo models (mouse gut colonization, pneumonia), his group aims to unravel the principles of bacterial communication in infection and ecology.

His publication record (2016–2024) reveals a sustained focus on AI-2-mediated signaling interplays with chemotaxis and metabolism. Key themes include gut colonization dynamics, interspecies bacterial competition, biofilm regulation, and phage-bacteria interactions. His work bridges Microbiology, Molecular Biology, and Infectious Diseases, emphasizing ecological context and in vivo validation.

Dr. Laganenka leads a research team comprising Technical Assistant Melissa Kivoloka. His position as Project Group Leader indicates successful independent grant acquisition, though specific funding sources are unreported. The group operates within the SYNMIKRO framework at the institute.

The Project Group Laganenka laboratory utilizes advanced methodologies including proteomics, flow cytometry, and murine infection models to dissect bacterial signaling networks in pathogenic and environmental contexts.
