 Research Interests:

My group has standardized a non lethal method of sampling minimal volume of blood from bats and Dna extraction. Dna thus obtained has successfully been used as template to amplify and sequence mitochondrial cytochrome b gene. Protocols have also been standardized to extract amplifiable DNA from wing biopsy samples. Molecular taxonomical studies are underway to understand the intraspecific phylogeny of various isolated and morphologically distinct populations of the fruit bat Cynopterus sphinx. Microsatellites are used for this work and preliminary results are being interpreted. We have been using various bioinformatics tools for sequence analysis and to study molecular evolution.
Work is in progress to develop reference acoustic library of various microbats present in southern India. We are in a process of recording echolocation calls from various species to isolate and identify call components that contains species specific signatures and can be used for identification of various species without capturing them. Besides, work is in progress to study intraspecific phylogeny using echolocation calls. Such a phylogeny is coupled with morphological and molecular studies for comparison with morphological and genetic species concept. We have already acquired data from populations across India and are in a process of analyzing them.
My lab has been working on echolocation of bats for past few decades and has enormous experience and expertise in studying them. As part of our effort to assess demography and dynamics of local populations of bats we have been doing capture mark recapture studies regularly. Survivability, dispersal patterns, immigration, emigration of these populations has been charted out to a certain detail.
For past one decade we have been using radiotelemetry studies with considerable success to assess foraging area, home range and juvenile dispersal of the fruit bat Cynopterus sphinx. Information obtained from such studies have helped us design further proposals to study the social structure and mating system of this fruit bat. Based on information acquired from radiotelemetry and capture mark recapture studies we have initiated a study on behavioural genetics of this bat.
Training bats is an important component for studying them under controlled captive condition. We have been using captive bats for various studies for past few decades,the most recent been the study on psychoacoustic of a microbat Megaderma lyra under habituation dehabituation paradigm.
