Through different science popularization program initiatives, such as the Taramandal programs (mobile planetarium), science popularization Talks, invited talks, and visits to schools, I have so far interacted with over 30,000 children of age group 7 – 21 years.

Online Science Popularization Program (my Start-up),2020
With a motivation to develop scientific temper among children (and all citizens), I am conducting science popularization programs through some innovative ideas & action plans. In this direction, I am running an online science popularization program for school students & other enthusiastic students of age group 7-21 by delivering and arranging talks and discussions related to astronomy, astrophysics, cosmology, biology, coding (and few other areas of science).
