My brother pursued his B.Tech from IIT BHU a few years back. He often talks about Dr. SK Sharma of the department of Mechanical Engineering. Sir is an extremely honest and hardworking person, and a teacher in the true sense of the word.
He treats his students like his own children, and spends all the money received from the department in providing equipment for their projects. Working under him is an honor. He helps his students in every possible way, and suggests amazing project ideas with a lot of enthusiasm. He motivates his students to publish their research papers on great platforms, and helps them in every possible way.
Sir is a very approachable and good teacher, and my brother will forever be indebted to him for his support and guidance.
To the best of my knowledge, most professors of the IIT BHU are approachable and down to earth. They provide help and support to any students asking for help. Prof. P.K. Mishra, Department of Chemical Engineering, IIT BHU is one of the most approachable professors in this IIT. He contributed in 6 patents, 71 research papers, many projects, books, and obtained various recognized awards. Still, he is supportive and friendly. Anyone can easily talk to him. He is also strict about discipline and rules. According to students, he is kind in nature and helps the students who reach out for help. To know more about him you can go to the official website of the IIT BHU.
