Project Summary

Darwinian evolution has shaped all life on earth. As scientists, we would like to harness these principles to create new molecules in real time - for example, to rapidly create therapeutic molecules to tackle pandemics.

However, the timescales of Darwinian evolution in living organisms are long and thus incompatible with fast discovery of new functions in the laboratory.

To overcome this limitation, we have established a synthetic orthogonal replication system in E. coli (EcORep) that enables selective and rapid mutation and selection exclusively on the DNA of interest without increasing the host genome's mutation rate. This technology allows us to create proteins with new functions in a few days.

The lab aims to leverage the orthogonal replication system for the accelerated evolution of complex biological functions to i) advance fundamental scientific understanding of molecular and cellular evolution, ii) develop biomolecules to tackle challenges in human-health, agriculture, and industry, and iii) generate large-scale enzyme datasets for training next generation protein design models.
