MY CREDO

General – I believe that Israel, which is almost devoid of natural resources, should focus on its human resources, in particular on scientists and engineers, to promote the Israeli economics. We, as scientists, must take part of this effort to promote science in Israel.

Drug Development - I believe that we as medicinal chemists take part in TIKUN OLAM = we Make the World a Better Place. This is our duty and privilege.

Industry – Currently there is some gap between academia and industry, which I believe should be bridged by joining forces and working-out common initiatives.

Community - I believe that the academia is like Aladdin’s treasure cave. The numerous treasures of knowledge should be shared with community.

Research

Medicinal Chemistry – development of drugs for the treatment of - type II diabetes, glaucoma, Alzheimer’s disease, osteoarthritis, and inflammatory bowel diseases; Diagnostics – development of fluorescent probes for diagnostics of breast cancer; Purinergic receptors; nucleotide metabolizing enzymes; chemistry of nucleosides/nucleotides and nucleic acids.
