Florence Nightingale

Shelli R. Johannes never warmed up to creepy crawly bugs, but she always loved zoology and biology. In fact, she can often be found on highways and country roads saving strays and other jaywalking critters, or volunteering with animal conservations groups like The Atlanta Zoo, The Dolphin Project, and animal rescue centers. Unfortunately, she learned early on that chemistry (a.k.a. cooking) was not her favorite science, often resulting in odd reactions and minor explosions. She lives in Atlanta with her husband, two kids, one bird, one fish, and two crazy-haired Doodles who, just like Einstein, all who seem to love fruit and dessert, but loathe veggies.
