Chemical Research Society of India: Convenor, Kanpur Chapter The objectives: Chemical Research Society of India is to enhance (i) Ability of chemical science research (ii) Emphasize the importance of chemistry as a science developed to societal well being (iii) Promote chemical education at all levels of learning and inculcate in student community. As a convenor, I have organized regional meetings on selected topics so as to provide an
opportunity to young researchers to congregate and share their excitements, organized lectures by
eminent scientists, promotion of activities in chemical education at all levels involving teachers and
students, organized activity such as exhibition/contests to enhanced the image of chemistry and visibility of
CRSI, promotion of academic research/industry interaction at various levels and celebrated important
milestones in chemical research.
Activities at Indian Chemical Society As a member of Indian Chemical Society, I have been involved in promotion of Science and
Technology in underdeveloped urban and rural areas. To this effect, many annual activities are planned to
teach the young children’s about the facets of Science and their application to people at large. Also,
workshops and seminars by eminent people are conducted on a regular basis to activate the young
students to pursue Science as a career. For my activities and contributions, I have been awarded “P.R.
Ray memorial award for the year 2002” by Indian Chemical Society, Kolkata, India.
