Debbie was very kind and humble person even though she was very famous. I met Debbie and worked with her while I was visiting JILA as a visiting student about 9 years ago, which I still remember as a special memory and thank her for her kindness to treat me like her stundents and give me an excellent research advice. I also thank her for giving me the opportunity because working with her helped me to come to the US to do my PhD, and I was able to meet my husband who was working with John at the time. For us, John and Debbie are very special people as our advisors and friends, and as our role models. We are extremely sad to lose Debbie. My deepest condolence to John, and their lovely daugher Jackie.
