Qualification: Ph.D.
Specialization: Plant Population Biology, Reproductive Biology Airborne pollen and fungal spores.
Personal Biography
Have research experience in plant-animal interactions (plant-pollinator, plant-seed disperser), gene flow system using molecular techniques and population demography of plants for more than fifteen years. Carried out studies on the pollination and seed dispersal aspects, population and genetic structure of endemic trees such as Palaquium ellipticum, Cassine kedarnathii and Garcinia imberti which were successful initiatives helping to evolve conservation measures for these species in their fragile ecosystems. Now actively engaged in the study of population genetic structure of Humboldtia unijuga variety unijuga and trijuga, an endangered tree species endemic to the Western Ghats and its conservation. Also having expertise on airborne pollen analysis and study of spores.
