    Johanna Teske

    • B.S., 2008, American University (physics)
    http://aurora.as.arizona.edu/~jteske/Welcome.html Areas of Interest: Stellar Astronomy, Planetary Astronomy, Astrobiology

    Unlike Clark Kent, 'Johanna' has a fascinating and productive secret identity that she pursues with passion during the day and, sometimes, during the wee hours of the night. Her research focuses on observationally constraining the compositions of exoplanets and their host stars, and exploring how their properties relate to each other, other planets, and perhaps our own solar system. Her alternate identity also requires some night-time observing, but this is Johanna's favorite aspect of her disguise and she frequents the MMT in Arizona and Mauna Kea in Hawaii. However, in times of trial, when there is a call for party platters, birthday treats, or coffee-discussion munchies, Johanna strips her day-time persona and becomes COOK-TASTICA, spreading happiness and yumminess where and when she can to those in need.
