Director's Message

The Institute of Nano Science and Technology (INST) has been established by the Department of Science and Technology, Government of India as a specialized centre of excellence to promote the growth of R&D, and exploit the application-potential of Nano Science and Technology in the country. The key areas to be focussed upon are Agriculture, Energy, Environment and Medicine. The Institute will bring together outstanding scientists from different branches of science and engineering. These scientists will aim to take up challenging interdisciplinary projects with a technology or device/product as the key deliverable. They are also encouraged to carry out their individual scientific research resulting in publications in the best journals alongwith their mandate towards devices/technology. INST is the first and only institute funded by Government of India with a mandate of pursuing primarily nanoscience and technology and we will strive to make it known as one of the best institutes of the country recognized globally.

Director's Message to INST Students

Dear Students,

Welcome to the Institute of Nano Science and Technology which is the first institute set up by the Government of India dedicated solely to nanoscience and technology. You are among the first few batches of PhD students and so will always be remembered in years to come as the initial young researchers of our institute. I am sure all of you will be very proud to enter this new institution and will have the privilege to carry the responsibility together with the scientists and administrators to give shape to the ideas with which this institute has been launched. We have tried our best to develop the infrastructure within a record time and with limited funds, so as to give you a proper research environment from the day you join the institute. As you will learn in due course of time, this institute has a strong interdisciplinary environment motivated towards carrying out outstanding research solving challenging problems which require interdisciplinary efforts and also deliver technologies/products to benefit the society. I urge you all to think ‘big’, think out of the box and we will help you convert your dreams into reality. Remember you are outstanding students and as Swami Vivekananda has said “Never be weak. You must be strong; you have infinite strength within you; Arise Awake and stop not till the Goal is reached”.

I wish you the very best and hope your desire to be an outstanding scientist is fulfilled by the enabling environment of our institute.

Good Luck
