Bogdan Dumitrescu received the M.S. and Ph.D. degrees in 1987 and 1993, respectively,
from University Politehnica of Bucharest, Romania. He is now a Professor with the Department of Automatic Control and Computers, University Politehnica of Bucharest, where he works since 1990. He held several visiting research positions at Tampere University of Technology, Finland, in particular that of FiDiPro fellow (2010-2013). He was Associate Editor (2008-2012) and Area Editor (2010-2014) at IEEE Transactions on Signal Processing. He authored the book “Positive trigonometric polynomials and signal processing applications” and coauthored “Dictionary learning algorithms and applications”. His scientific interests are in optimization, numerical methods, and their applications to signal processing, especially using sparse representations.
