(born June 8, 1947) is an American developmental biologist
and Nobel Prize-winner.
Born in South Bend, Indiana
, he attended John Carroll Catholic High School
in Birmingham, AL before attending the University of Notre Dame
for his undergraduate studies (B.S., biology), and Yale University
(Ph.D., biology) for his graduate work. In 1978, he moved to his first independent job, at the European Molecular Biology Laboratory
and moved from Heidelberg to Princeton University
in the United States
Much of his research has focused on embryogenesis
in the fruit fly Drosophila melanogaster
, specifically in the patterning that occurs in the early Drosophila
embryo. Most of the gene products used by the embryo at these stages are already present in the unfertilized egg and were produced by maternal transcription during oogenesis
. A small number of gene products, however, are supplied by transcription in the embryo itself. He has focused on these "zygotically"
active genes because he believes the temporal and spatial pattern of their transcription may provide the triggers controlling the normal sequence of embryonic development.
Saturation of all the possible mutations on each chromosome by random events to test embryonic lethality was done by Eric Wieschaus.(PSY IITK)
, he was awarded the Nobel Prize in Physiology or Medicine
with Edward B. Lewis
