| Donald D. Brown is a Staff Member
and Director Emeritus of the Department of Embryology
of the Carnegie Institution of Washington in Baltimore,
MD. He received an MD degree from the University of Chicago.
After an internship he trained in research at the National
Institutes of Health, and the Pasteur Institute. He began
studying developmental biology when he arrived at the
Department of Embryology in 1961 as a postdoctoral fellow.
He studied gene structure, and expression in the days
before recombinant DNA using ribosomal RNA and 5SRNA genes
that had been purified from the genomic DNA of Xenopus
laevis. In 1990 Brown changed his research to the molecular
basis of thyroid hormone-induced amphibian metamorphosis.
Each tissue and organ of a tadpole is a target of one
simple hormone and responds with its own program of development.
Brown is past president of the American Society for Developmental
Biology and the American Society for Cell Biology. He
is a member of the US National Academy of Sciences, the
American Academy of Arts and Sciences, and the American
Philosophical Society. In 1981 he founded the Life Sciences
Research Foundation, an agency that raises money from
companies, foundations, and other sources to support postdoctoral
fellows in all areas of the life sciences. |
