Research Summary:

We study the steps of gene expression in eukaryots with emphasis on mRNA localization and translation regulation. We apply diverse methods to understand how the translation of mRNAs is regulated, what are the RNA sequences that are important for regulation and which RNA binding proteins are involved in this process.
