Biomonitoring and Bioprospecting
Our research focuses on extremophilic bacteria, particularly psychrotolerants from Arctic and Antarctic regions, metallotolerants, and strains resistant to toxic compounds (including antibiotics). Using structural and functional genomics, we investigate their metabolic pathways and resistance mechanisms, with an emphasis on whole-genome sequencing and mobile genetic elements (MGEs). We apply advanced computational analyses to explore the ecological and evolutionary roles of MGEs and their biogeography.

We assess the taxonomic and functional diversity of microbial communities in pristine and anthropogenically-shaped environments, aiming to understand adaptation and seasonal microbiome dynamics. One of the key research areas is the ecological and molecular characterization of antibiotic resistance, supported by our custom-developed bioinformatic tools and curated databases.

We also conduct biomonitoring studies focused on the detection and analysis of pathogens, antibiotic resistance genes, and virulence factors across diverse environments. These efforts support applications in both human and veterinary medicine, enhancing our understanding of the environmental reservoirs and transmission routes of clinically relevant traits.

In parallel, we engage in bioprospecting of extreme environments for microbial strains, novel enzymes, and metabolites with high biotechnological potential, including their applications in regenerative agriculture and environmental biotechnologies.

Back to the pool, back to the roots

Recently, Przemek visited his former primary school - SP5 in Wyszkow, where he was invited as an alumnus to meet with students and share his career path. During the meeting, Przemek talked about how he became a scientist, what everyday research work looks like, and what kind of projects are currently being carried out by our team.

The visit was also a return to a very special place - the school where he trained competitive swimming as a member of UKS “Polonez” Wyszkow for nearly eight years. Przemek emphasized that this sports background still plays an important role in his scientific work. Determination, regular training, patience, and the ability to deal with failures are essential not only in sport, but also in science. In this sense, experiments may resemble training sessions, while scientific publications and grant applications can feel like important competitions that require long-term preparation.

It was a great opportunity to show students that the path to science can begin in many different places - including a swimming pool.
