Our Chancellor Amma places a strong emphasis on research activities. Rather than simply memorising all the knowledge that has been accumulated in a particular field, Amma wants us to delve deeper, to explore, to discover for ourselves. She is always encouraging the students and faculty of Amrita University to undertake research and development work that will benefit society.

They are heeding her call: exciting, original research is taking place in the fields of information technology, engineering and medicine, among others. At CEN also we have undertaken and succesfully completed several research projects, some of which are listed below.

In keeping with the research thrust at Amrita, Center is actively involved in the areas of Computational Linguistics and Natural Language Processing. A massive translation project is underway that aims to develope tools to translate web content from English to Indian languages. This initiative, when complete, will enable every child in India to access information in his or her own mother tongue. Research is also ongoing in the area of speech translation.

Research at CEN is multidisciplinary in nature. The key research areas are:

Research at CEN requires financial foundation which is met by undertaking projects funded by the Ministry of IT, ISRO, DRDO, NPOL, MHRD, DST, DIT, CDAC, and Coconut Development Board, Government of India. Total research grant is over 33 million INR.
