National Level workshop report on
“Recent Trends in Nanotechnology”
held 18th & 19th Jan 2016
- Chief guest of the inaugural function: Dr. Dinesh Rangappa
- President of the inaugural function: Dr. Peter Fernandes
- Vote of thanks of the inaugural function : Dr. Raghavendra Rao
- Introduction of Chief Guest: Prof. K. V. Suresh
- Coordinator :- Prof .Kiran H
In his chief guest’s speech, Dr. Dinesh Rangappa stressed on interdisciplinary team work. He also advised the society to change its attitude in the field of research. He insisted colleges to come up with more and more research programmes get acquainted with the government funded projects and build teams of research fellows of interdisciplinary areas. He was also more concerned about the issues with the basic sciences. He emphasised on the importance of working on basic sciences rather than mere concentrating on the technology side. During his speech, he also quoted that ”our success will be measured by others but our satisfaction should be measured by ourselves”. So, he insisted on striving for the satisfaction rather than success.
Dr. Peter Fernandes, president of the inaugural function
President of the inaugural function, Dr. Peter Fernandes, in this presidential speech, insisted on conducting these kinds of workshops at least for one week so that more amount of knowledge can be shared in the respective areas. He also advised faculties to replenish themselves and upgrade their knowledge by attending these kinds of workshops.
