Milagros Valdes, my beautiful wife of 11 years, lost her battle with a rare and vicious form of breast cancer on April 15, 2012. I want to thank all of my colleagues at Caltech for their understanding and support during this most difficult time. I really do have the best job and coworkers imaginable. I also want to thank my professional friends who sent so many kind messages and care packages. Your support helped me and my family enormously. I surely could not have coped without my community. Many hugs are coming your way next time we see one another at meetings/conferences. I am deeply humble and grateful.
