Research Interests:
Primary research interest is in the area of developmental neurobiology of insects. What type of neuroactive substances are present within the central neurons? What changes occur in the localisation, axonal arborization, and peripheral innervation of these chemically identified neurons during post embryonic development? How much influence the peripheral targets have in the organisation of central nervous system during metamorphosis? What is the role of central neurons in the differentiation of peripheral target? Answers to these questions are being sought by using experiments involving transplantation or extirpation of organ primordia (leg, eye, etc.) to alter numerical and spacial relationship between central nervous system and its target organs during post embryonic development of the flesh fly Sarcophaga bullata.
