Stanley Norman Cohen
Stanley Norman Cohen ( born February 17, 1935 in Perth Amboy, New Jersey) is an American geneticist and professor at Stanford University in Stanford, California.
Life
Cohen studied at Rutgers University in New Brunswick, New Jersey and earned a bachelor's degree there in 1956. He then studied medicine at the University of Pennsylvania in Philadelphia, Pennsylvania and graduated in 1960 with a MD from.
Cohen received a PhD Student ( Assistant Professor in 1968, Associate Professor 1971) at the Faculty of Medicine at Stanford University in Stanford, California. His entire academic career over, he remained at this university. In 1969 he was Head of Clinical Pharmacology, 1975, he received a full professorship for medicine in 1977 for genetics. Between 1978 and 1986 he was Head of the Department of Genetics. Since 1993 he has been Kwoh -Ting Li Professor in the School of Medicine.
Work
Cohen was interested in early for plasmids, genetic material of bacteria, which is located outside of the bacterial chromosomes. He managed to smuggle plasmids in other bacteria and thus their descendants. Use of restriction enzymes he could in 1973, together with Herbert Wayne Boyer genes transplant of others, even higher organisms in bacteria and force the expression of these genes.
Boyer and Cohen's research led to the development of techniques for the cloning of genes ( splicing, recombination, replication). The work of both researchers are the basis for genetic engineering.
Current work focuses on the development and spread of antibiotic resistance.
