In 2007 he received the National Medal of Science from President Bush at a ceremony at the White House for elucidating the biochemical basis of signal amplification in vision, pioneering the development of high density microarrays for genetic analysis, and authoring the standard undergraduate biochemistry textbook, Biochemistry. It is now in its ninth edition and also edited by Jeremy Berg, John L. Tymoczko and Gregory J. Gatto, Jr.
