Staff Scientist; Weizmann Institute of Science, Israel

I am a physicist working at the intersection of chiral molecular systems, spintronics, and quantum materials. My research focuses on understanding the fundamental mechanisms of the chiral-induced spin selectivity (CISS) effect and exploiting spin-dependent transport phenomena to develop next-generation electronic, sensing, and quantum technologies.

My work combines molecular design, nanoscale device fabrication, and magneto-transport measurements across multiple length scales, ranging from single-molecule junctions to functional thin-film devices. A central goal of my research is to bridge fundamental spin physics with practical device architectures that operate under ambient conditions.
