Ora Kedem ( Hebrew אורה קדם, born as Orah Katz on July 2, 1924 in Vienna ) is professor emeritus for physical chemistry at the Weizmann Institute for Science , Israel , and winner of the Israel Prize . Her work focuses on research into transport processes across biological and polymer membranes as well as processes for seawater desalination .

biography

Ora Kedem fled from the Nazis in Austria and emigrated in 1940 to Palestine to present-day Israel. From 1947 to 1949 she was a lieutenant in the Israel Defense Forces . She studied chemistry at the Hebrew University of Jerusalem and received her doctorate in 1953 from the Weizmann Institute of Science in Rechovot . Together with the physical chemist Aharon Katchalsky , she published fundamental work on the analysis of the behavior of biomembranes in the context of the thermodynamics of irreversible processes . In 1961 she was awarded the Israel Prize of the State of Israel for her services in the field of life sciences .

After teaching at Harvard Medical School in Massachusetts (1963 to 1964), she worked as a faculty member at the Weizmann Institute from 1965. In 1970 she became a full professor ( min ha-minyan ) at the chair for polymer research. In 1974 she founded the Department of Membrane Research, which she headed for several years as director.

In 2005 she was elected a member of the National Academy of Engineering . She is co-founder of the Ben Gurion University of the Negev . In 2007 she received an honorary doctorate from the University of Twente .
