Biography

I received my PhD degree in Zoology in 2000 from Manonmanam Sundaranar University, Tamil Nadu and I studied diversity and ecological structure of fishes in Western Ghats streams, India. My research included species distribution patterns, community structure, spatio-temporal changes in resource (food and space) partition among co-existing species, conservation of rare and threatened species and effects of human disturbance on aquatic resources. I described three new species and found out several new records of fishes from Western Ghats. Currently, I am working on microhabitat requirement for rare and threatened fishes, resource partitioning, aquatic habitat monitoring and conservation and management of aquatic resources.
