That sounds like an exciting event! It seems like there was a distinguished lineup of speakers and a significant focus on cutting-edge topics like nanomaterials for agriculture and food. Dr. Tessy Thomas, the Vice Chancellor, inaugurating the International Lecture Series indicates the importance of global perspectives in academia. Dr. Diriba Eticha's felicitation address and Dr. R.S. Rimal Isaac's talk on nanomaterials likely brought valuable insights to the audience. Dr. Lalu Gladson Robin, as the Director of International Affairs, played a crucial role in organizing and convening the program, ensuring its success and relevance on an international scale. It's events like these that contribute significantly to the exchange of knowledge and ideas in higher education.
