Research Description

Lena Vincent is developing and deploying a novel empirical approach to study the physicochemical principles governing the onset of life-like behaviors in non-living chemical systems as part of a NASA-funded project to understand the origins of life. She uses an analog of experimental evolution to enrich for ensembles of simple molecules that can cooperate, grow, and respond to selection. The results of her work are expected to shed light on the conditions that yield spontaneously emerging, evolvable chemical systems on early Earth and in general, which is likely to have a bearing on the search for life elsewhere in the universe.
