Animals use visual information to find home, locate mates, avoid obstacles and capture prey. I am interested in understanding how animals learn, memorise and recall spatial information. Towards this, I study the behaviour of animals in their natural habitat, map the information content in the environment, and analyse the sensory and neural tissues required for information processing tasks. My research has largely focused on insects to take advantage of the inter- and intra-specific variation in size and tasks that they carry out in discrete ecological and temporal niches.

A second aspect of my research aims to promote native insect pollinators and develop methods and techniques to control pests and diseases of native insects.

I have a keen interest in photography and love to experiment with macro-photography when time permits. Some of my pictures are here.
