Chemistry is one of the most useful field of science, filled with future discoveries for the utility and safety of the human race and most importantly studying Chemistry is great fun. The Department of Chemistry provides a rock solid platform to the students in chemistry which will allow them to establish a strong understanding over a wide range of spectrum.

We introduced Chemistry curriculum that is mostly research-based, constantly upgraded to include the current and relevant researches. Here we teach our students all the aspects of chemistry and train them to be competent in different fields of science related to the vast area of chemistry. We empower our students to educate and explore themselves and to have a clear knowledge in scientific world.
