Biography

I come from Łódź, a very nice city in central Poland. I studied biology in the University of Łódź, where I got my master’s degree in environmental biology (2008). For my PhD I moved to Jagiellonian University (Kraków, Poland), where I began to use population genetics to study speciation and hybridization in amphibians. I finished my thesis under supervision of prof. Jacek M. Szymura (2013) and then continued to work as a post-doc in the lab of Wiesław Babik (2016). In January 2017, I started my second post-doc in the lab of Christian Landry, where I’m currently studying evolution of pathogenic fungi causing Dutch Elm Disease, as a part of BioSAFE project supported by Genome Canada.

 

Research interests

I am interested in hybridization and the way it affects speciation, divergence and adaptation of populations from the genomic point of view. In the past years I have been particularly interested in adaptive introgression of immune genes between amphibian species, and the role of balancing selection in this process. Currently I am investigating hybridization in the context of rapid emergence of several lineages of tree-killing fungus causing deadly Dutch Elm Disease. My other areas of interest include evolution of genome size and gene repertoire of pathogens as a consequence of adaptation to hosts and vectors.
