Dr.zakir naiq is good in science related topics in the Quran but otherwise his knowledge on sujects of the Quran is not more than mullah...
Islamic research centers r very good steps bcoz we need research in every subject of the Quran... n to me people who do research in different fields n provide work in undiscovered meanings n mysteries of the Quran...their work is not less than azal ibadat bcoz their work help people in geting better understanding of the Quran n also encourage people of other religions to the Islam.
