There are several excellent professors in every department at NIT Trichy. In the Chemical Engineering department, there are a number of faculties who have their qualifications and achievements worth listing. Some of them are listed below.

• Dr. T. K. Radhakrishnan- He is one of the most notified professors in NIT Trichy. Dr. Radhakrishnan has over 60 papers presented in his career and has written several journals.
• Dr. N. Anantharaman-He is famous for his relaxed classes and teaching style in the Chemical Engineering department. He has over 60 publications in total and also has authored few books on several topics.
• Dr. (Mrs). K. M. Meera S. Begum- She teaches the most important “Mass Transfer” subject in Chemical Engineering, and takes a lot of classes. She provides students with some excellent fundas that are relevant and very useful. She also has several publications in her career.

Though there are several other excellent faculties at NIT Trichy, the list above is exclusive to the Chemical Engineering department only.

The faculty at IIT Ropar is great. The majority of the professors hold a Ph.D. degree. They are cooperative and provide proper guidance in projects as well as examination preparations.

The lectures are enough for understanding the courses and you would not even need to take help from tuitions. Professors explain the topics in an easier way so that you can easily grasp their subject matter.

However, when it comes to attendance, you are required to maintain a 75% attendance. The professors are not lenient if the students miss the classes. The same goes with the assignments and presentations which need to meet the deadline. Delaying your submissions would only bring you in a tough position.

A relative of mine used to be a student of BIT Mesra. She and a number of her peers have chosen Mr. Anup Kumar Keshri to be the best professor at BIT Mesra.

• Professor Keshri himself is an alumnus of BIT Mesra and he was a student of the Computer Science Branch. Despite being in the CS Department, Professor Keshri was impressed by Professor P.K. Choudhary who did not belong in the department. His teaching abilities caught the eyes of Professor Keshri.
• Professor P.K. Choudhary belonged to the Mechanical Department. He taught engineering drawing. 
• Even though Prof. Keshri was not a student of Mechanical Engineering, he did a paper on Professor Choudhary’s subject in 1996. 
• In addition to that, in spite of not being a student, Professor Keshri is sure that after some revision, he would be able to take classes in Mechanical Engineering.

He is thankful to Professor Choudhary for teaching him the ‘Language of Engineers’, on which Professor Keshri did the paper in 1996. He did not have to refer to any textbook for preparing himself for the paper. He wishes to be a teacher like Professor Choudhary.

Although IIIT Hyderabad has many excellent professors. But there is one professor, who is a pure gem. He can actually change the way you look at and solve Mathematics. He is none other than Dr. Kannan Srinathan. His ever-smiling face and his ability to simplify even the most complicated concepts in a much simpler way will surely make you fall in love with Discrete Mathematics, the course he mastered in.

Yegnanarayana is also quite popular among students. He teaches Speech Signal Processing and Artificial Neural Networks. He prepares for his lectures for 2 hours, although he has been teaching for 40 years.

My friend studied at MIT in 2013 and he says there are many reputable names from different departments like Prof. K Jeyaraman in the Aeronautical Engineering department, or Dr. PK Kanagasabapathy from the Instrumentation Engineering department, or Dr. A Rajadurai who was the former dean of MIT- he was an expert in Metallurgy and is one of the best professors owned by MIT. 

Nevertheless, because my friend has his personal favorites, I'd write about them here -

• Late Prof. VK Narayanan was dedicated to his profession and his students. His room was next to the internet room on the admin floor. My friend used to converse with him on any topic necessary.
• It was because of him that he discovered KB Chandrasekar, the same KBC of the AU KBC research centre where my friend is an employee now. He forsook TCS to join there.

There have been innumerable instances where my friend was guided and helped by prof KVN. 

• One such incident is of the day when someone from the All India Radio came to him to introduce a new program to him on Information Technology. 
• He had approached him to ask him for lectures on computers to be relayed on AIR, and Prof Mathiazhagan had already done the first episode; but Prof KVN calmly made him understand that he should give such opportunities to young students.
• He pointed at my friend and highlighted his erudition on knowledge to do with the internet, which landed him with 20+ episodes.
• Not only this, he once helped a student to apply to foreign universities and she landed in a good US university, one more student with his help in association with my friend got a job with Blackberry and now lives in San Francisco. 
• Once my friend wanted to build a website for MIT and guess who provided all the support - Prof. KVN did. He learned HTML, found a domain name, and created official MIT emails for all the staff members.

He had been a professor, friend, and guide to my friend. 

To become an assistant professor at IIT Ropar you must first obtain a PhD. This is the minimum eligibility criteria for any IIT to apply for the post of assistant professor. 

Then you will have to compete with many other candidates and to stay above the competition you will need to have an outstanding academic career throughout. 

You will also need to have various published papers in many international and reputed journals. This will give you an edge over others.

This is a suggestion beyond the scope of this question. But if you can start low in a company and struggle for 2-3 years, I believe that you can land a more lucrative and satisfying job later on. Doing an M.Tech and then a Ph.D. will take a very long time.
