Our work is primarily question-based, rather than organism-based, and current study systems that include

  • Insects (primarily butterflies and bees)
  • Social spiders (Stegodyphus sarasinorum)
  • Plants
  • Reptiles

We also work on questions at the level of landscape/community:

  • Myristica swamps
  • Rocky plateaus of Northern Western Ghats
  • Deciduous forests in Bhimashanker

 

Ongoing research projects

The Vanasiri and BEE group websites have more detailed information on respective research projects. Below is a sample of ongoing projects

  • Landscape ecology and pollinators of Myristica swamps.
  • Evolution of sociality in spiders
  • Spatio-temporal dynamics of diversification of hyper-diverse taxa
  • Sensory ecology of honey bee vision
  • Hostplant ecology of Acraea butterflies
  • Phylogenetics  and comparative biogeography of plants of the Western Ghat
  • Phenotypic plasticity in satyrine butterflies in relation to seasonal environments
  • Macroevolutionary dynamics of lizard colour patterns
  • Diversification of uropeltid snakes in the Indian subcontinent
  • Geneflow and divergence across rocky plateaus in the Northern Western Ghats

RESEARCH FACILITIES

ICREEE has excellent facilities for many kinds of ecological and evolutionary research projects. We currently operate out of a transit campus in Thiruvananthapuram, but have well-equipped labs and research infrastructure. We have several growth chambers for controlled-environment experiments, outdoor facilities for rearing insects, rooms for indoor experiments, molecular labs for genotyping work, a microscopy unit, high-speed videography equipment, etc. We will also shortly have a state-of-the-art greenhouse complex in our permanent campus. The permanent campus is located at Vithura, ca. 45 km from Thiruvananthapuram, the capital of the state of Kerala. This mountainous, rainforested region in the southern India is part of the Western Ghats and Sri Lanka biodiversity hotspot, and harbours a great degree of endemism. The campus of about 200 acres includes substantial streches of semi-evergreen, mixed-deciduous and riparian jungle. The reserved forest adjoining our campus is contiguous with one of the best tracts of primary rainforest in India – the Agasthyamala Biosphere Reserve, which includes the Peppara, Neyyara & Shendurney Wildlife Sanctuaries, as well as the Kalakkad-Mundanthurai Tiger Reserve. The campus therefore serves as a splendid laboratory for field-based experiments. Moreover, the rich biodiversity within and around the campus provides a great many model systems for experimental work.

In addition, we also maintain two field stations – Bhimashanker (adjoining Bhimshanker WLS) in Maharashtra and Kulathupuzha (adjoining Shendurney WLS) in Kerala.

JOIN US

We welcome inquiries from motivated students and postdocs interested in joining us. We are open to interns (IISER-TVM and external), PhD students and Postdoctoral Fellows. For more detailed information please refer to respective ‘Openings’ pages of BEE Lab and Vanasiri.

Current opening(s):

A postdoctal position is available under ICREEE (IISER-TVM Centre for Research and Education in Ecology and Evolution). ICREEE consists of the research groups of Ullasa Kodandaramaiah and Hema Somanathan. We invite applications for a postdoc with one of us preferably on one of the research themes mentioned below, but applicants are also free to propose projects in other research areas.

Ullasa Kodandaramaiah

  • Prey-predator interactions
  • Life-history trait evolution
  • Insect-plant coevolution

Hema Somanathan

  • Plant-pollinator interactions
  • Insect navigation
  • Dispersal ecology

The candidate will have the flexibility in designing projects in discussion with Hema or Ullasa, and can involve undergraduate students & interns. The IISER-TVM Vithura campus is an excellent place for many kinds of studies in ecology and evolution. If interested in the position, please get in touch with one of us (ullasa@iisertvm.ac.in, hsomanathan@iisertvm.ac.in) for discussions before sending in your formal application. There are of course several ongoing projects in both labs that a postdoc can be part of, but selection is based partly on the ability of the candidate to come up with good research questions.

DEADLINE: 15 March 2017

SALARY: Rs. 43,200 (Rs 36,000 + 20% Housing Rent Allowance)

DURATION: 1.5 years

RESEARCH:

SELECTION: The formal advertisement with details of how to apply are at http://iisertvm.ac.in/openings/read_opening/191.phpx

LIFE IN KERALA AND THIRUVANANTHAPURAM (TRIVANDRUM): The picturesque campus is in Vithura, which is 40 km from the coastal city of Thiruvananthapuram. Some people prefer to live near the campus, but many commute from the city. Thiruvananthapuram is the capital of Kerala, and has a rich cultural heritage. It is within a stone’s throw away from world-famous beaches such as Kovalam and Varkala, and lovely backwater tourism areas such as Poovar. Several hill stations (e.g Ponmudi) and wildlife sanctuaries are close by. Being a major medical tourism destination, the city has excellent medical care facilities. The quality of school education is good and the medium of instruction is English, which is widely spoken in the state.

It is a relatively small city, and the cost of living tends to be considerably lower than in bigger Indian cities. A 2-bedroom apartment can be rented for Rs 8,000 – 10,000 per month. There are plenty of options for dining out – a meal at a decent local restaurant can start from Rs 50, but a good meal with a drink even in a five-star hotel need not cost more than Rs 1000. Costs for groceries and other daily needs can be looked up here (www.kada.in). Taxis can be hired from Rs 10 per km (with a minimum fare of Rs 50).

VISIT US

We are a small group and welcome the opportunity to interact with other researchers in Ecology and Evolution. You can visit us, for instance, to…

  • Give a research seminar
  • Use our campus for part of your field or laboratory based research.
  • Collaborate with one of us

Depending on the nature of your visit/projects, we can help with accommodation.

If interested in visiting, write to either Hema or Ullasa.
