R.K. Gaur Department of Biotechnology, Deen Dayal Upadhyaya Gorakhpur University, Gorakhpur, Uttar Pradesh, India. Prof. (Dr.) R.K. Gaur earned his Ph.D. in 2005, and is now a Professor at the Department of Biotechnology, Deen Dayal Upadhyaya Gorakhpur University, Gorakhpur, Uttar Pradesh, India. His Ph.D. was on the molecular characterization of sugarcane viruses, i.e., mosaic, streak mosaic, and yellow luteovirus. He received a MASHAV fellowship of the Israeli government for his postdoctoral studies and joined The Volcani Center, Israel and Ben-Gurion University, Negev, Israel. In 2007 he received the Visiting Scientist Fellowship from the Swedish Institute, Sweden to work at Umea� University, Umea�, Sweden. He received a postdoc fellowship from ICGEB, Italy in 2008. He has made significant contributions on sugarcane viruses and has pub lished 130 national/international papers, authored 17 edited books and presented about 50 papers at national and international conferences. He has been honored as a Fellow of Linnean Society, a Fellow of the Royal Society of Biology, a Fellow of the Society of Plant Research, a Fellow of the Society of Applied Biology (FSAB), and a Fellow of the International Society of Biotechnology (FISBT). He has received many other awards, including the Prof. B.M. Johri memorial Award, Society of Plant Research (SPR); Excellent Teaching Award by Astha Foundation, Meerut; UGC-Research Teacher Award; Young Scientist Award in 2012 in Biotechnology by the Society of Plant Research (SPR), Meerut; and Scientific and Applied Research Center Gold Medal Award in 2011 for outstanding contribution in the field of Biotechnology. He has visited several laborato ries in the United States, Canada, New Zealand, United Kingdom, Thailand, Sweden, and Italy.

Dr. Pradeep Sharma received his Ph.D. in 2002 on the cloning and characterization of cotton leaf curl viruses. He performed his postdoctoral research (2006 2008) at Tohoku University, Japan with Prof M Ikegami as a JSPS fellow, where he worked on RNA silencing. He also undertook postdoctoral work at the ARO Volcani Center, Israel with Prof Y Gafni (2006 2006), focusing on the nuclear import of genes using yeast one hybrid system, as a DST scientist (2006), as a visiting scientist at South Dakota State University (2011) investigating allele mining and comparative genomics in rice, and at Oklahoma State University (2016) on small noncoding RNAs.
