A Doctor of Philosophy also known as PhD is a doctoral research degree and the highest academic qualification that one can attain. This degree normally requires three to five years of full-time research work to complete a thesis that represents an original contribution to your field.

Various streams of PhD research are there, which include Science, Humanities, Management, Engineering, Art, Pharmacy, Law, Mass Communication, and Commerce. PhD holders are permitted to use the title Doctor with their name.

A PG degree is required usually for the admission to a PhD programme. However, after a UG degree, direct admission to PhD programmes is also available at the IITs, NITs, IIITs, and the Academy of Scientific and Innovative Research.
