Epigenetics and Stem Cells

At the Institute of Epigenetics and Stem Cells (IES),  we aim to unlock a cell's full potential by understanding how a single cell can give rise to all the cells in our body at the beginning of life.

About Our Research

Research Groups

GFP-labelled early mouse embryos

Torres-Padilla Lab

Epigenetics and cell-fate in early mammalian development

We combine high-resolution microscopy with single-cell genomics to study the epigenetic principles underlying cellular reprogramming in the mouse embryo.

View Lab
Transcription-Replication Conflicts under different temperatures

Hamperl Lab

Chromosome dynamics and genome stability

We study how DNA replication and transcription can occur simultaneously without major accidents that cause DNA damage and genome instability.

View Lab
Cellular Decision Making

Scialdone Lab

Physics and Data-Based Modeling of Cellular Identity Changes

We aim to understand the molecular bases of cell identity changes by combining single-cell and spatial omics data analysis with physical modeling.

View Lab

Battich Lab

Quantitative Cell Biology

We are interested in the strategies that cells use to control gene expression levels and variability during differentiation.
