Jacqueline Barton

Jacqueline Barton probes DNA by shooting electrons through it. Using custom-built molecules to direct these electrical currents, she can locate genes, see how they are arranged, and scan them for damage.
Barton hopes that these techniques will lead to new ways to diagnose diseases and treat them through DNA repair. To further this end she cofounded GeneOhm Sciences in 2001, which became part of Becton, Dickinson and Company in 2006.
