In the past two decades I have developed professional expertise and made significant contributions to the improvement of agriculture on both Israel and the international levels, and in the past few years particularly to the dairy industry. Under my direction, a patent for S. aureus vaccine, one of the major causes of udder infection in dairy animals was developed and registered. In addition, the results of my studies connecting the quality of milk in the bulk tank to its influence on product yield in the dairy industry were implemented by Afimilk Afikim, for on-line classification and channeling of milk for increased yield when producing different dairy products. This technological achievement has the potential to result in a radical increase in the economical profitability of cheese production and is currently under final experimental evaluation by two dairy plants in Israel.

These developments in agriculture are integrally related to my professional career as a researcher, in which I implemented my expertise in immunology to conduct extensive research to promote understanding of the immune response related to specific pathogens as a sub-system of the animal as a holistic whole. In years of cumulative research this approach guided my work. My primary focus of research has been on infective agents such as Escherichia coli, Staphylococcus aureus and Pseudomonas, as related to target hosts in a variety of animal species, mainly in broilers, cattle, sheep and goats leading to developing means of combating diseases. Through understanding the complex relationship between the agent and the host animal, I developed appropriate vaccines to avian colibacillosis and S. aureus mastitis. Continuing this line of research, recently I have examined the bacteria genome as expressed in the development of the disease.
