The forty- something globe - trotter, known as the "Scientoon man" in the CDRI campus and outside, has achieved quite a feast by fusing complex scientific theories with dollops of humor, a concept reported to be going down well with audiences, whether in Philadelphia or Bangkok, Shimla or Stockholm. His experiments began way back in 1988, says Srivastava, and were “triggered by the lukewarm response speakers receive at scientific seminars."

Says Srivastava, “I remember it was the first lecture of my life on that too on a very dull and comprehensive topic "Development of Drugs & Pharmaceutical Industry in Developing Countries" in a conference held at National University of Singapore, Singapore, The worst part was that I had my lecture prepared for around 45 minutes but chairman said “You have only 10 minutes for the lecture. That’s all.” I used few novel type of science cartoons in order to make my lecture more informative, interesting and impactful. I was so nervous that I didn’t see the watch and when I finished my lecture it was 45 minutes over and there was no warning bell by the chairman.
