Dr. Krishna Kumar G

Assistant Professor
Attached Department: 
Address (Residence): 

Dr. Krishna Kumar G has obtained his B.Sc. in Agriculture from KAU-College of Agriculture, Vellanikkara (2004-08). For Masters, he specialized in Plant Physiology from the most coveted ICAR-Indian Agricultural Research Institute (IARI; 2009-11). He continued the specialization in Plant Physiology for Doctorate from IARI (2011-18). He received ICAR-JRF Fellowship for his M.Sc. and UGC-CSIR fellowship for his Ph.D. programme. During specialization, he got well versed with major cereal crops wheat and rice, and responses to abiotic stresses in plants. He obtained advanced skills in root phenotyping, bioinformatics, gene cloning, genome editing and generation of transgenics.

Previous experiences

Worked as Senior Research Fellow in an ICAR-NASF project on genome editing in rice (2018-19).

Worked as Assistant Professor, Department of Plant Physiology, School of Agricultural Sciences and Technology, NMIMS, Shirpur, Maharashtra (2019-21).
