Amy was probably the best postdoc I have ever had. What she has did in my lab, i.e. the first purification and reconstitution of the binding-protein-dependent transport system, was a colossal achievement, but even more importantly she did all this without my help. What we now know about the mechanism of ABC transporters largely came from her work after she became an independent investigator. She was also a wonderful, kind, human being. I will miss her very much.
