Dioscuri Centre for Chromatin Biology and Epigenomics

Dioscuri is a program initiated by the Max Planck Society, managed jointly with the National Science Centre (Poland) and mutually funded by the Polish Ministry of Science and Higher Education and the German Federal Ministry of Education and Research.

Mission of the lab

We use stem cell models, high throughput sequencing technologies (ChIP-seq, ATAC-seq, RNA-seq, Hi-C), CRISPR-Cas9 mediated genome editing, and computational tools, to decipher the regulatory networks orchestrating astrocyte functions in mammals and to understand the interplay between chromatin topology and gene expression.

We are also a part of the NIH Regulome Project
