Benjamin Horwitz

Education/ Resume:

Benny Horwitz studied biology and physics as an undergraduate at Tel Aviv University. He did his PhD on fungal photobiology (1984) in Plant Genetics at the Weizmann Institute. After postdoctoral research in photobiology at Syracuse University and at the Carnegie Institution’s Department of Plant Biology, he took a faculty position at Technion in 1987, founding a lab to study cell signaling pathways of filamentous fungi, in particular their relevance to fungal-plant interactions.

Research Summary

Mechanisms of signal transduction in fungi. Reception and transduction of host signals in fungal-host interactions and their relevance for disease; role of conserved eukaryotic signaling genes in fungal signal transduction; gene expression patterns controlled by these pathways. Signaling by transcription factors that sense light, redox state or pH. Small molecule signals and their perception. Photobiology and spectroscopy of biological photoreceptors, in particular blue light receptors
