Joanna Kasprzak started her scientific career in 2006 when she obtained a Master's degree in bioinformatics, focusing on the analysis of enzymes responsible for RNA modifications. She then specialized in protein and RNA structure prediction and phylogenetic analysis. In 2013 she was awarded a PhD from Adam Mickiewicz University in Poznan, Poland under a supervision of Prof. Janusz M. Bujnicki. A major element of her thesis was the development of PyRy3D, a software tool for the modeling of large macromolecular complexes, and its application to the prediction of structure for a complex involved in DNA repair pathways. This software has been shortlisted by the "Killer Application" Award Committee at the ISMB/ECCB conference in Vienna, Austria, in 2011 and has been received with enthusiasm by its first group of users.
In 2013 she was hired in the International Institute of Molecular and Cell Biology in Warsaw as a PostDoc. Her research now focuses mainly on modeling of large macromolecular complexes. In her work, apart from using common modeling tools and pipelines, she continues development of PyRy3D program. To understand and predict function and mechanism of action of complexes of interest, Joanna collaborates a lot with experimental biologists who deliver her data from cryo-EM, SAXS, chemical cross-linking and FRET experiments.

Grzegorz Chojnowski obtained his PhD in biophysics from the University of Warsaw in 2010, under the supervision of Prof. Matthias Bochtler. He is currently a PostDoc in the group of Prof. Janusz M. Bujnicki at the International Institute of Molecular and Cell Biology in Warsaw. His main research interests are the development of new tools for the macromolecular crystallography (http://diber.iimcb.gov.pl) and structural studies of RNA and protein-RNA complexes (http://iimcb.genesilico.pl/rnabricks). He is also an experienced user of both experimental (x-ray crystallography, SAXS) and computational methods for protein and RNA structure determination.
