What are the ways to complete the ph.d in mechanical engineering, after post graduation
After you complete your M.Tech with specialisation in some area, you can apply for PhD in any engineering college that offers a doctoral programme.
You will have to take the NET exam and clear it. Thereafter in consultation with your professor, who will also be your guide you can choose a particular area of research and proceed accordingly.
Usually even before you register for PhD you must consult the head of department of the college/institution you want to pursue research in order to know the relevant areas of research the college facilitates.
