G. Ylla

Welcome to my personal evolving virtual space.

About me:

Group leader of the Bioinformatics and Genome Biology Laboratory at the Jagiellonian University. I obtained postdoctoral training at the Department of Organismic and Evolutionary Biology at Harvard University (2019-2021) and at the University of Florida (2018). I have a strong background in biology and evolution combined with computational skills acquired through my B.Sc. in Biotechnology (UVic, 2012), M.Sc. in Omics Data Analysis (UVic, 2014), Ph.D. in Biomedicine (UPF, 2014-2017).

My Research Interests


Evolution is, ultimately, the explanation of all biological processes and biodiversity. Any piece of biology one can now observe has been shaped through a long evolutionary history. I am interested on understanding how through genetic changes new phenotypes have emerged and evolved. I am particularly interested in large evolutionary innovations. For example, how insects invented the complete (Holometabolous) metamorphosis that allowed them to virtually conquer any terrestrial ecosystem?

Gene Expression Regulatory Networks

Genomes alone can’t explain phenotypes. Thus, if we truly want to understand how characters are determined, we need to understand how gene regulatory networks work. In my research I integrate different types of “omics” data to model the gene regulatory networks that can help us to understand how phenotypes are determined and how they have evolved.


Bioinformatics is merely a tool. A big and powerful tool, a way to interact with biological data, a way to make questions to genomes, a way to understand the gene expression, a tool which must be used correctly.
