About Me
Joined as Scientist B in the Garden Management, Education, Information and Training Division of JNTBGRI on 30th May 2011. Presently working as part of the in-house project on ‘Development of a Conservatory for Aquatic Macrophytes in JNTBGRI’, and has collected more than 140 species/ varieties. Aponogeton appendiculatus, Crinum malabaricum, Hygrophila balsamica, Limnophila indica, Ludwigia adscendens, Nymphaea malabarica, Trapa natans, Victoria amazonica, Wolffia arrhiza, etc., are the major attractions. 12 species/ varieties of Nymphaea are also conserved. Engaged in taxonomic as well as ecological studies especially heavy metal accumulation and phytoremediation potential of aquatic macrophytes.
