My heartfelt condolences to Amy's family and friends. When I first met Amy, I was deeply impressed by her enthusiasm for her research, her friendliness and how much she was admired by her students and her peers. I have benefited greatly from her vast knowledge and her willingness to share it. For me, one encounter at an ABC transporter research meeting sums up her wonderful and caring personality (and I have told this story to many people over the past few years): I asked her how large her lab was at the time and her answer was: "It is HUGE!". I asked how many people that referred to.
