Matthieu Komorowski wanted to be an astronaut. Still does. The French-born anesthesiologist, currently getting a PhD at Imperial College London, applied to the European Space Agency in 2008. But he knows his chances are limited. \u201cBeing basically a medical resident I didn\u2019t get very far in the selection,\u201d Komorowski says. \u201cBut I\u2019ve been working on building up my skills.\u201d Among those skills: administering anesthesia for surgery.
