Research interest

The development of an embryo involves a series of spatio-temporally ordered cell fate assignations. These decisions are controlled by mechanical and chemical inputs and lead to the emergence of different tissues and organs. From the level of tissues these decisions appear to be deterministic giving rise to highly robust and reproducible patterns. However, on the single-cell level gene and protein regulatory processes, which underlie cell fate decisions, are subject to stochastic effects which are inherent in biochemical reactions. Understanding how this macroscopic order on a multi-cellular scale arises from stochastic processes on a molecular and cellular level is poorly understood.

I am interested in how cells make decisions about their fate during development. Particularly, my current research focuses on how cells interpret various environmental signals and integrate them to make precise and reproducible decisions. Furthermore I am interested to which extent this interpretation depends on prior experience (i.e. the internal state of a cell) versus the spatio-temporal dynamics and the statistics of those external cues.

Studying general design principles of core circuitries controlling cell fate decisions as well as elucidating how cells integrate and process information about their environment (including neighboring cells) to generate specific responses might help to understand how organisms go from stochasticity at the molecular and cellular level to deterministic behaviors on the tissue and organismal level.
