Babak Hassibi (Persian: بابک حسیبی, born in Tehran, Iran) is an Iranian-American electrical engineer, computer scientist, and applied mathematician who is the inaugural Mose and Lillian S. Bohn Professor of Electrical Engineering and Computing and Mathematical Sciences at the California Institute of Technology (Caltech).
During 2008-2015 he was the Executive Officer of Electrical Engineering and Associate Director of Information Science and Technology.
[citation needed] His research is broadly in communications, signal processing and control.
Among other works, he has shown the h-infinity-optimality of the least mean squares filter,[1][2] used group-theoretic techniques to design space-time codes[3] and frames[4] and to study entropic vectors,[5] performed information-theoretic studies of various wireless networks[6][7][8][9][10] (such as determining the capacity of the MIMO wiretap channel[11]), constructed tree codes for interactive communication and control,[12] developed various algorithms and performance analyses for compressed sensing and structured signal recovery, studied epidemic spread in complex networks, and co-invented real-time DNA microarrays.
[18] His grandfather was the late Kazem Hassibi, an Iranian academic, parliamentarian, National Front leader, and oil adviser (Under-Secretary of Finance, 1952 to 1954) to Mohammad Mosaddegh during Iran's oil nationalization.
