Artificial Biology, Molecular Evolution, Astrobiology

Our research focuses on reconstructing molecular time machines to explore and attempt to rebuild lost histories. We tackle challenging questions to understand life’s fundamental innovations. Our approach enables the reconstruction of biomolecule-scale macroevolutionary trends that span billions of years of Earth history and is a fundamentally new methodology with which to study the origins and early evolution of life.
