Biography

Ziv Goldfeld joined the School of Electrical and Computer Engineering at Cornell University as an assistant professor in July 2019.
 
During the 2017-2019 academic years, he was a postdoctoral research fellow in the Laboratory for Information and Decision Systems (LIDS) of the Electrical Engineering and Computer Science Department at MIT. Before that, Goldfeld graduated with a B.Sc., M.Sc. and Ph.D. (all summa cum laude) in Electrical and Computer Engineering from Ben Gurion University, Israel, in 2012, 2012 and 2017, respectively.

Research Interests

Goldfeld's research interests include information theory, statistical machine learning, high-dimensional and nonparametric statistic, applied probability and interacting particle systems. Specifically, his recent work focuses on information-theoretic analysis of deep neural networks (DNNs), convergence rates of empirical measures smoothed by Gaussian kernels (which has to do with mutual information estimation between layers of a DNN), and data storage in stochastic Ising models. During his graduate studies, Goldfeld focused on physical layer security, cooperation in multiuser information-theoretic problems and multiuser channel and source duality.
