Tanaya Beatty plays feisty emergency room doctor Shannon Rivera on the NBC medical drama "The Night Shift."

A recent medical school graduate, Rivera is eager to prove herself, but her spunky, outspoken nature doesn't sit well with everyone.

A rising star, Beatty was cast as the lead female role of Sacagawea on HBO's "Lewis and Clark" miniseries, opposite Casey Affleck. She also recently worked alongside Clive Owen and Juliette Binoche in the feature film "Words and Pictures."

Beatty is probably best known for her supporting role in "The Twilight Saga: Breaking Dawn - Part 1" from the hugely popular "Twilight" franchise.

She also had a significant recurring arc on CBC's popular "Arctic Air" and recurred on "The 100" and "Continuum."
