KARI BYRON

Kari Byron is a born tinkerer and explorer. By the age of 5, she was experimenting on her sister, and using her dolls as crash test dummies. Luckily for her parents, they always caught her in time — right before her little sister took a ride down a laundry chute or recruited her for an "around-the-world" attempt on the playground swings.

After graduating from San Francisco State University and traveling the world, Kari began her career as a sculptor and painter, holding successful exhibitions at some of San Francisco's leading galleries. "Artist" was only one of many hats she wore while searching for her place in the world. Her sculpting skills — and penchant for odd jobs — soon led her into the field of model-making and toy-prototyping, which led to a job with Jamie Hyneman at M5 Industries. It was at M5 that Kari got her big break with Discovery Channel's "Mythbusters" …and the rest is history.

Kari is thrilled to host "Head Rush," an all new, one-hour, commercial-free program on Science Channel, made for middle-school students, but fun for the curious kid of any age. Her aim is to inspire and excite us about the wonders of science and show science at work in our everyday lives. No subject will go unexplored! Kari dives into mathematics, science, technology, engineering, natural history and space with hands-on experiments, video shorts, viewer questions and answers, games, and special celebrity visits from other members of the Discovery TV family.

Watch Head Rush Monday-Friday at 4 PM and Saturday mornings from 7-9 AM!
