Taught general genetics, advanced genetics, biotechnology, biochemical genetics, molecular genetics, mutagenesis, immunogenetics, developmental genetics, and evolution to undergraduate and graduate students of constituent colleges of the PAU. Also taught genetics and zoology to undergraduates (September 1976-June 1980) at Howard University, Washington, D.C., USA, as a Graduate Teaching Assistant.
Professor Miglani was invited by School of Agricultural Biotechnology, PAU in March 2010 as Adjunct Professor, to teach molecular genetics, epigenetics and biotechnology to B.Sc. (Biotechnology)/B.Sc. Technology (Biotechnology), M.Sc. (Biotechnology) and Ph.D. (Biotechnology) students, which he continued till December 2010. He was rehired by PAU in January 2011 as Visiting Professor and he worked in this capacity till August 2020. He takes keen interest in popularization of science of genetics by way of radio talks and writing popular articles for magazines and newspapers. During last 11 years he has focused on writing of books, review papers and book chapters.
He has been associated with The Journal of Plant Science Research, published by the Society for the Promotion of Plant Science Research, Jaipur (India), for more than 12 years in different capacities, including editor of the journal.
