Curriculum Vitae

Mini bio

R. J. Cintra (SM'2010) earned the doctorate degree in electrical engineering from the Universidade Federal de Pernambuco (UFPE), Recife, Brazil, and joined as a faculty member of the Centre for Natural and Exact Sciences, UFPE, in 2005.

He has held visiting scholar appointments at the University of Akron, Ohio, USA; the Département Informatique, INSA Lyon, France; the INRIA/IRISA Lab, University of Rennes 1, France; the University of Calgary, Canada; and the Florida International University, Miami, USA.

He was an associate editor for IEEE Geoscience Remote Sensing Letters; for IET Circuits, Devices & Systems; and for Springer Circuits, Systems, and Signal Processing. Currently he serves as an associate editor for the Journal of Communication and Information Systems; and as a subject editor for IET Electronics Letters.

His long-term topics of research include: approximation theory for discrete transforms, theory and methods for digital signal/image processing, computationally efficient statistical algorithms, and probabilistic methods.


    • Jesus Christ - "Thou knowest the commandments, Do not commit adultery, Do not kill, Do not steal, Do not bear false witness, Defraud not, Honour thy father and mother." [Mark 10:19]

    • Jesus Christ - "Why do you not judge for yourselves what is right?" [Luke, 12:57]

    • Thomas Aquinas - "It is written (Ex. 20:15): "Thou shalt not steal." ... If anyone consider what is meant by theft, he will find that it is sinful on two counts. First, because of its opposition to justice, which gives to each one what is his, so that for this reason theft is contrary to justice, through being a taking of what belongs to another. Secondly, because of the guile or fraud committed by the thief, by laying hands on another's property secretly and cunningly. Wherefore it is evident that every theft is a sin."

    • Plautus - "Nothing but heaven itself is better than a friend who is really a friend."

    • Hippocrates - "[The] art is long, life is short, opportunity fleeting, experiment dangerous, judgment difficult."

    • Vergilius - "Felix qui potuit rerum cognoscere causas."

    • Benjamin Franklin - "They who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety."

    • Richard Feynman - "Reality must take precedence over public relations, for Nature cannot be fooled."

    • John N. Mitchell - "The finest steel has to go through the hottest fire."

    • Thomas Paine - "Moderation in temper is always a virtue; but moderation in principle is always a vice."

    • Douglas Horton - "The art of simplicity is a puzzle of complexity."

    • Richard Hamming - "The purpose of computing is insight, not numbers."

    • Edsger Wybe Dijkstra - "Computer Science is no more about computers than astronomy is about telescopes."
