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 showed and presented academic talks in 1989 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 published in April 1990.[1] He organized the first wavelets conference in the United States at NJIT in April 1990,[2] and in 1992,[3] he co-authored the first wavelet-related engineering book published in the literature entitled Multiresolution Signal Decomposition: Transforms, Subbands and Wavelets. His more recent research activities include nonlinear phase extensions of complex transforms like Fourier techniques and their applications,[4] and quantitative finance problems.
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 between 1998–2000. He was the vice president for research and development of the IDT Corporation 2000–2001. He was 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 sits on the boards of directors of a few companies and an investment fund on CleanTech. 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. Most recently, he was a Visiting Professor at Courant Institute of Mathematical Sciences of the New York University (2009–2010).
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.[5]
According to the Mathematics Genealogy Project, as of September 2010, Akansu had a total of 18 doctorate students.[6]
