We mourn the loss of Robert Dirks, who tragically lost his life in the Metro-North train crash in New York on February 3, 2015. Robert wrote the first lines of code for NUPACK and made indelible contributions to its algorithms. Robert was brilliant, fun-loving, creative, and generous; he was a model scientist, collaborator, and friend. We will miss him and always remember him with fondness and respect and gratitude.
