Tamara Robertson is an Engineer turned Science Communicator working to inspire young children in the pursuit of S.T.E.M. She received her Chemical & Biomolecular Engineering degree from N.C. State University in her home state of North Carolina. Following graduation, she spent a little under a decade working in Plant Designs, Vaccines Development, Additive Development and Packaging Design before moving into a role as an Engineer Consultant so that she could pursue Outreach and Science Communication Full Time in 2015. She remains passionate talking to kids across the nation about the exciting world of Science and showcasing to them that where their journey started doesn’t define where it ends. As a kid, Tamara learned to rebuild engines with her dad. After gaining a biomolecular engineering degree, she designed vaccine processes and facilities and helped manufacture flu vaccine to help combat avian flu. But it hasn't always been lab coats for Tamara; she's also an accomplished actor and TV host, also a finalist on Mythbusters: The Search. She's subsequently appeared on several other science TV shows.
