Phage Consultants helps companies fight and prevent bacteriophage infection.

Our Team of scientists has in-depth knowledge and vast experience not only in phage research, but also in environmental microbiology and molecular biology. The team is led by the company’s founder Dr Marcin Los, an expert in the field of phage biology with particular focus on phage development in fermentation setups. Our five full-time scientists, most  holding a PhD degree, and a MSci-level technician all have an excellent scientific record confirmed by multiple peer-reviewed publications.


Dr Marcin Łoś

CEO and owner
For over twenty years, Marcin has worked in the field of bacteriophage research, as shown by the vast record of 65 scientific publications in various topics revolving around bacteriophage biology. Marcin has worked in both academic and industrial settings all over Europe (such as University of Bradford, UK; Martin Luther University Halle-Wittenberg, Germany; University of Oulu, Finland; or Institute for Silicon Technology, Germany), including work as an Assistant Professor leading his own team of researchers at the University of Gdańsk (Poland). Author of multiple biotechnological production technologies, owner and co-owner of multiple patent applications, Marcin is considered an expert in the field of combating and preventing phage contamination in biotechnological processes and in the development of phage-based technologies.

Dr Joanna Łoś

CSO and Research Specialist
Bacteriophage biologist and expert in phage and prophage biology, Joanna received her PhD from the University of Gdańsk (Poland) in 2010, where she later continued her work as an Assistant Professor carrying out her own research. Her expertise includes induction and development of prophages including Shiga-toxin encoding prophages, highly sensitive phage and prophage detection methods, metagenomic analyses of complex microbial samples, and biology of virulent phages. Joanna is an expert in work with strict anaerobes, human and veterinary pathogens, and their bacteriophages. Joanna is an author of 25 scientific papers in various fields of microbiological research, mostly involving bacteriophages.

Dr Sylwia Zielińska

R&D Scientist
Molecular biologist and expert in bacteriophage detection and isolation from environmental samples. Sylwia received her PhD in molecular biology in 2017 from the University of Gdańsk (Poland), where she focused on metagenomics of environmental microbial samples with particular focus on the isolation of their genetic material. Sylwia has a vast experience in isolation and identification of new phages from highly diverse samples, including developing novel strategies for identification and DNA isolation from obtained bacteriophages.

Dr Klaudia Milewska

R&D Scientist
Molecular biologist and bacteriologist, expert in biotechnological production of bacteria in bioreactors. Klaudia finished her PhD studies at the University of Gdańsk (Poland) in 2018, in her project she optimized culturing conditions of marine bacteria, as well as studied their adaptative responses and regulation. Klaudia uses her expertise to devise, optimize, and scale up new technologies and procedures for culturing, maintaining, and purification of diverse bacteria ranging from human pathogens to extremophiles in both aerobic and anaerobic conditions.

Aleksandra Bebel, PhD, PMP

Research Scientist, Communications and QA Specialist
Molecular and structural biologist, expert in molecular biology of mobile genetic elements. Aleksandra received her PhD in molecular biology in 2015 from EMBL Heidelberg (Germany) and University of Glasgow (UK), followed by a postdoctoral fellowship at the University of Chicago (USA) as a recipient of the EMBO fellowship. In her previous work, Aleksandra focused on molecular understanding of mobile genetic elements of human pathogenic bacteria, such as SCCmec of MRSA or pathogenic islands of Helicobacter pylori. She contributes her expertise to development of novel phage-based technologies and takes care of company’s social media communications and quality control practices. In 2021, Aleksandra was certified as a Project Management Professional (PMP).

Mgr Klaudyna Krause

Research Scientist
Molecular biologist and expert in bacterial virulence, Klaudyna finished her PhD studies at the University of Gdańsk (Poland) and is about to submit her thesis focusing on molecular basis of pathogenicity and virulence of Vibrio cholerae. On top of strong background in bacterial biology (particularly in DNA replication and metabolism), Klaudyna has vast experience in culturing pathogenic bacteria in, on small scale and in bioreactors. She uses that experience to optimize culturing conditions of various bacterial species required for bacteriophage propagation and for routine sample testing.

Julia Schoenhoff

Julia is about to complete her MSci work focusing on bacterial metabolism and its link to DNA replication. Julia uses her experience for phage discovery and characterization, and is also responsible for preparation of culturing media and other components necessary for daily operations.
