Yonina C. Eldar (Hebrew: יונינה חנה אלדר; born 25 January 1973) is an Israeli professor of electrical engineering at the Weizmann Institute of Science, known for her pioneering work on sub-Nyquist sampling.

[5] Eldar moved back to Israel in 2002 and became a senior lecturer in the Electrical Engineering Department at the Technion, Haifa.

[5] Upon receiving the IEEE Kiyo Tomiyasu Award (2016), her research work and its implications were described by the award committee: Yonina Eldar’s pioneering work on sub-Nyquist sampling and reconstruction of sparse analog signals has demonstrated the potential to improve radar, medical imaging, communication, and storage systems.

Bridging the gap between theory and real-world applications, Eldar developed the concept of “Xampling” for sub-Nyquist sampling and built hardware prototypes to demonstrate how the technique works in practical settings.

Eldar’s innovations will enable portable ultrasound machines for emergency and rural medicine, radar systems with improved resolution, and better wireless capabilities for cognitive (intelligent) radio transmission and reception.

[1]Eldar is the author of the book Sampling Theory: Beyond Bandlimited Systems (2015)[10] and co-author of Compressed Sensing (2012)[11] and Convex Optimization Methods in Signal Processing and Communications (2010),[12] all published by Cambridge University Press.
