Igor S. Pessi, PhD
Polar Microbial Ecologist

I am a microbiologist specialized in the study of polar microbial communities. My research focuses mostly on the use of molecular ecology methods such as metagenomics and metatranscriptomics to explore the diversity and functional capabilities of microbial communities across the polar regions. I have a MSc degree in Cellular and Molecular Biology from the Federal University of Rio Grande do Sul (UFRGS, Brazil), and a PhD in Sciences from the University of Liège (Belgium). I am currently a Researcher at the Finnish Environment Institute (Syke) (Finland).
