M. Masroor A. Khan is a Professor at the Department of Botany, AMU, Aligarh, India. After completing his PhD from AMU, he got an offer from Cambridge University, the UK, for another PhD degree. However, Prof. Khan preferred to join the Ohio State University, USA, as a PDF (1987-88). On his return from the USA, he worked as Pool Scientist (CSIR) and as a Research Associate (CSIR and UGC) and then joined as Assistant Professor at this University. Prof. Khan has published more than 200 research papers in internationally recognized journals and ten books on the subject concerned. He has guided 17 PhDs, 2 MPhils, 40 MSc projects, and 20 fieldwork projects. Prof. Khan is working to promote medicinal and aromatic plants' productivity and active ingredients using different strategies, e.g., applying mineral nutrition, PGRs, and nanoparticles. Prof. Khan has significantly contributed to establishing Radiation-Processed Polysaccharides (RPPs) as plant growth promoters. He has involved the research collaboration with Bhabha Atomic Research Centre, Mumbai, to formulate the RPPs that would help masses increase the productivity of medicinal and aromatic plants and their active constituents. Prof. Khan has successfully achieved this goal so far. He has published his research on the effects of RPPs on medicinal and aromatic plants in high-impact factor journals such as Carbohydrate Polymers, Industrial Crops and Products, etc. His other field of research is nanoparticles. Prof. Khan has found that applying some nanoparticles could enhance the essential oil production of some aromatic plants. Recently, he published a patent for the first time in this department to the Govt. of India on enhanced peppermint production through the application of inexpensive silicon nanoparticles. On the other hand, Prof. Khan has developed many study materials and launched more than 120 class notes, PPTs, etc., available on his web page for the convenience of the students. He visited about 20 countries and presented his research there.
