Sahar received his BSc in Life Sciences from Tel Aviv University. His graduate work was carried out with Prof. Shimshon Belkin at The Hebrew University of Jerusalem, where he developed a panel of microbial sensors for the detection of antibiotic compounds and other toxicants. During his post-doc, Sahar developed a high throughput method to map the small RNA interactome in bacteria (RIL-seq). Sahar studied novel small RNAs and characterized RNA pairs associated with the key RNA-binding proteins, Hfq and ProQ. Sahar first conducted his post-doctoral work in the lab of Prof. Hanah Margalit at the Hebrew University, and later in the lab of Dr. Gisela Storz at the National Institutes of Health, USA. Sahar's favorite activity in his office is to drink coffee.
