Alexa Halford is a prime example of what happens when you go to college in MN and take up space. She became a space physicist, and because she got her PhD in Oz, sometimes says x, y, zed instead of x, y, zee.

Currently she is the NASA Goddard Ionosphere, Thermosphere, Mesosphere Lab chief which means she leads the most down to Earth lab within the NASA heliophysics division. Though we still have our head in the clouds most days.

When not having way too animated discussions about plasma waves, you can find her at the local bookstore coffee shop or in the garden.

Alexa will speak to us about Welcome to the Ionosphere - our connection to space.
