Demonstrated that adult stem cells isolated from muscle can be converted into functioning nerve cells, a concept now being explored in mouse models for treatment of Parkinsonism and spinal cord injury.

Demonstrated that the REST protein is a new member of an interconnected regulatory network used by embryonic stem cells to replicate themselves (self-renewal) and retain the capacity to differentiate into numerous cell types (pluripotency).

Demonstrated that mutations accumulating in DNA sequences that control gene expression within a population of animals may be a source of variation for the evolution of morphological differences between species.
