About Myself I am Prof Pankaj Khanna, teaching Organic Chemistry in the Department of Chemistry of Acharya Narendra Dev College since 2009. I love to demonstrate the beauty of chemistry of carbon to the students and synthesize new compounds for the betterment of the society. I was selected as a Vice Chancellor's fellow (University of Delhi) for the year 2014 and was recently selected as a  Digital Literacy Champion by Campus of Open Learning, University of Delhi, for further training at Edinburgh College, Scotland, UK, July 2015. Educational qualification I did B.Sc.(Hons) in Chemistry in 1998 from Rajdhani College and M.Sc. in Organic Chemistry from Hindu College, University of Delhi in 2000. I qualified CSIR(NET) examination held in December 1999 and have my Ph.D. in Synthetic Organic & Natural Product Chemistry with Professor S.C. Jain, Department of Chemistry, University of Delhi. I have also done a Post Graduate Diploma in Intellectual Property Rights from IGNOU.
