Research background and interest:

I conducted my postdoctoral research at Stanford University, Institute of Stem Cells, School of Medicine, and Stanford Hopkins Marine Station. My PhD research was in cancer, viral, and pregnancy immunology. During my Postdoctoral research I was working on immune system histocompatibility and stem cell transplantation using a unique aquatic protochordate model.

The comparative immunology laboratory at Ben Gurion University that we are establishing will focus on several research directions:

i) Studying immune mechanisms of cellular recognition and histocompatibility, for translation to medical application as well as aquaculture.

ii) Studying and characterizing immune and stem cells for aquatic organisms, for immune modulation and stem cell transplantation.

iii) Studying, modifying, and developing vaccines for aquaculture. Including the use of vaccination vectors with the existing research at the Jacob Blaustein Institutes for Desert Research such as plant plastid and/or microalgae.
