David Osterman – Advisory Board Member

David Osterman works at Ball Aerospace in Boulder where he helps develop instruments for observations from space. In childhood David’s interest in science was encouraged by his mother’s love of nature and father’s help in math homework. This led to memorable experiences catching butterflies, growing crystals, peering at stars through a telescope and marveling at the creatures in lake-water drops under a microscope.

David received a doctorate in physics from Columbia University. Since then his career path has traversed the landscape of STEM careers, from Science to Technology to Engineering (but not yet Math). After working in physics research at Brookhaven National Laboratory he moved on to technology commercialization for a high- tech start-up company. Now David is a Systems Engineer at Ball Aerospace where he is part of a team developing a temperature mapping instrument for Jupiter’s fascinating moon Europa, the subject of a future NASA mission.

Cool Girls is important to David for several reasons. On a personal level he wants his children, including his daughters, to have the opportunity to engage with STEM and STEAM subjects as he could as a child, with experiences that inspire wonder and appreciation of the natural world. He would also like his daughters to be free to pursue whatever interests them without being discouraged by stereotypes about girls. In a time when science is under pressure to bend to political forces he would he would like to contribute to the strengthening of free inquiry. Working with girls on STEAM activities is one way to do that.
