Ali Akansu

Ali N. Akansu is a Turkish American scientist best known for his contributions to the theory and applications of sub-band and wavelet transforms.

Biography

Akansu received his B.S. degree from the Istanbul Technical University, Turkey, in 1980, his M.S. and PhD degrees from the Polytechnic University, Brooklyn, New York, in 1983 and 1987, respectively, all in Electrical Engineering. Since 1987, he has been with the New Jersey Institute of Technology where he is a Professor of Electrical and Computer Engineering. He was also a Visiting Professor at Courant Institute of Mathematical Sciences of the New York University.

He showed that the binomial quadrature mirror filter bank (binomial QMF) is identical to the Daubechies wavelet filter, interpreted and evaluated its performance from a discrete-time signal processing perspective.[1][2][3] He organized the first wavelets conference in the United States at NJIT in April 1990,[4] and in 1992,[5] and co-authored the first wavelet-related engineering book published in the literature entitled Multiresolution Signal Decomposition: Transforms, Subbands and Wavelets.[6]

He made contributions in the areas of optimal filter banks,[7][8] nonlinear phase extensions of discrete Walsh-Hadamard transform [9] and discrete Fourier transform,[10] principal component analysis of first-order autoregressive process,[11] sparse approximation, [12] financial signal processing and quantitative finance.[13][14] He co-authored the book entitled A Primer for Financial Engineering: Financial Signal Processing and Electronic Trading.[15]

He was a founding director of the New Jersey Center for Multimedia Research (NJCMR), 1996–2000, and NSF Industry-University Cooperative Research Center (IUCRC) for Digital Video, 1998–2000. He was the vice president for research and development of the IDT Corporation, 2000–2001, the founding president and CEO of PixWave, Inc. (an IDT subsidiary) that has built the technology for secure peer-to-peer video distribution over the Internet. He was an academic visitor at David Sarnoff Research Center (Sarnoff Corporation), at IBM's Thomas J. Watson Research Center, and at Marconi Electronic Systems.

He is an IEEE Fellow (since 2008) with the citation for contributions to optimal design of transforms and filter banks for communications and multimedia security.[16]

According to the Mathematics Genealogy Project, as of February 2016, Akansu had a total of 21 doctorate students.[17]
