It was a lifetime experience to also organise the event with Doordarshan Bangla with so many cooperative hands. Behind the scene, many were involved in organising this program, Dr Varsha Pavithran, Dr Sumantra Pal, Subham Ghosh, Bhaskar Jana, KV Chinmaya, Vinitha Johny, and the complete technical team of Doordarshan. I was overwhelmed to understand how Doordarshan Kolkata Centre despite having minimal technical resources organised this efficiently. One said that to organise the even the Doordarshan Kolkata Centre went through a storm. I am super-happy that this program has influenced Doordarshan to start a weekly program on science communication. Many congratulations to Doordarshan for this.

13.10.2021: Aren't these signals beautiful? Single molecules are flowing inside a nanofluidic channel. This data certifies that I am a 'molecular plumber'. More than proud sometimes, I feel quite powerful that I can create pipes with cross-sectional diameter as small as our cellular nanopores and able to see light emitting from them one at at time. This means, we are one step closer to 'real' artificial intelligence or synthetic biology.

I am glad to receive Kuang as a bachelor student who has a strong inquisitiveness. Supervising a bachelor thesis is not an easy task, especially, if you believe in the phrase of 'bad teachers are criminals', if you want to enhance the inquisitiveness of your student, and if you want to motivate one to be in academia. I am happy that I could maintain all these three criteria successfully.
