Divya Uma is a faculty with the School of Arts and Sciences.
Before Azim Premji University, she was a post-doctoral fellow at IISER Trivandrum examining hunting and web-building behavior of social spiders, and personalities in these spiders. Prior to this, she did another post-doctoral stint at University of Maryland, Collage Park, USA, looking at the response of crayfish towards predatory cues, and also exploring non-invasive methods of imaging neuroanatomical structures of crayfish. Divya obtained her doctoral degree from Georgetown University, USA where she looked into predator-prey interactions between wasps and spiders.
Her recent work includes investigating Batesian and aggressive mimicry in ant-mimicking spiders against various predators; ecology of floral color changing plants and their pollinators; spatio-temporal dynamics of web architecture in social spiders.
A guided self-study around conceptual and analytical abilities as well as writing and reading that is necessary for the field of biology.
Looking at how animals respond to their own kind and other species while trying to survive.
How are the interactions between organisms influenced by physical, chemical and biological features?
Core aspects of growth theories in economic thought.
Basic quantitative knowledge and abilities.
