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.
