Adam Ossowicki

Post-Doctoral Researcher

Microorganisms are all around us. I always wanted to know how bacteria, fungi, viruses and other micro-lifeforms cause macro‑changes around us. In my work, I focus on bacteria and fungi associated with plants and insects. I am interested in how diversity and dynamics of microbiomes shapes the beneficial services provided by microbes but also how it shapes their pathogenicity. For me, the most fascinating part of my research is discovering interactions between microbes and between microbes and their hosts. With the fast developing sequencing technologies we can take a closer look into the microbial communities easier than ever, nevertheless many questions still remain unanswered. I believe that integrating genomics and metagenomics with phenotypic and metabolic data can bring us much closer to understanding how the micro-world works, how it affects our environment, and us.

In the Above-belowground Interactions Group my research is focused on microbes and microbiomes of Jacobaea vulgaris (ragwort) and its highly specialized herbivore Tyria jacobaeae (cinnabar moth). In my work I want to zoom into the functional aspects of plant-insect-microbe interactions in that system.
