Areas of Interest
Research
The aims of my research are to better understand the mechanisms underlying energy homeostasis (body weight regulation), circadian physiology and their mutual interaction. We use human subjects and animal models in order to assess:
A. Energy balance in beta-thalassemia patients (with Prof Ariel Koran and Dr. Carina Levin, Ha'Emek Medical Center).
B. The role of leptin ontogeny (leptin surge at neonatal age) in susceptibility to obesity.
C. The role of the endogenous circadian rhythm period-length, i.e. it deviation from the environmental light-dark cycle, in the susceptibility to obesity.
D. Clay as absorbers (with Prof. Giora Rytwo, MIGAL and Tel-Hai Collage).
E. The particle usage of Bioelectrical Impedance Analysis technique for body composition analysis in the Israeli beef and dairy cattle industries (with Mop Tzafon).
F. The role of water availability in weight gaining of stopping-over migratory birds (with Dr. Nir Sapir Haifa University).
