Among his positions at the Hebrew University's Faculty of Agriculture, he previously served as chairman of the committee for graduate students in agriculture and applied biology (1986-1990); chairman of the teaching committee (1980-1983); Acting Head of the Department of Horticulture (1978) and Chairman of Plant Science Studies (2001-2003). He was also a member of the Hebrew University's Senior Appointments Committee for Life Sciences (1991-1993), and a member of the Hebrew University's Senior Appointments Committee for Humanities and Social Sciences ( 2000-2003). He held two positions in the Bard Fund for Agricultural Developments United States-Israel: Chairman of the Foundation's Interdisciplinary Evaluation Committee (1982), and Chairman of the Field Crops and Orchards Evaluation Committee (2004-2006).

## Contributions

His research has focused on general agriculture and on various citrus species.
He is primarily known for his research on citron genetics and shape variability,. He developed an auxin which is instrumental in preserving the style and stigma of the citron; these features figure prominently in determining the halachic status of individual citrons for use as etrogim.
Since retiring from the Hebrew University, he has continued his work on projects to lengthen the shelf life of produce and to increase the productivity of wheat.
