Debbie chaired my PhD thesis examination committee in 2005. She read through my thesis carefully and corrected my poor English. Debbie is certainly one of the people at JILA from whom I had leant a lot how to become an experimental AMO physicist – Her model story motivated many graduate students even though I was not her student. I still remember I was invited to present my atom-chip work at the Cornell-Wieman-Jin joint group meeting in March 2004 and received much encouragement for continuing my research career. In May 2012, Debbie visited my lab in Hong Kong (with Jun Ye) and witnessed the cold atom research in Hong Kong. As part of JILA and CU-Boulder, Debbie will be deeply missed.
