Achyut Kumar Banerjee is a plant ecologist with Bachelor’s and Master’s Degrees in Botany from the University of Calcutta, Kolkata.

He works in the domain of Biological Invasion, one of the main components of global change. He wants to understand the dynamics of the invasion process, starting from the introduction of an organism into a new environment to its ability to cross different barriers to become an invasive species. In this pursuit, his interdisciplinary research approach has two major components:

  • For his PhD at the Indian Statistical Institute (ISI, Kolkata), he conducted field and controlled experiments to characterise the ecophysiology of an invasive species of global concern and the dynamics of the invaded community.
  • His Postdoctoral work at the Sun Yat-sen University in China focused on assessing the invasion risk of multiple species at a global scale. These studies used large databases, geospatial technologies, and an ensembled predictive modelling framework.

Achyut has also conceptualised and collaboratively produced a novel database having the ecological and socio-economic attributes of the alien flora in India, called the Indian Alien Flora Information Database (ILORA). In line with the interest of his Postdoctoral Research group, Achyut has also worked on the Phylogeography of several mangrove species distributed in the Indo-West Pacific region.

All his studies are focused on countries of the Global South and provide practical and easy-to-implement – a) management measures for the invasive species and b) conservation insights for the threatened mangrove taxa.

Achyut loves reading books (with a bias for historical nonfiction) and capturing the natural world (with a bias for flower and macro photographic genres). He has recently started writing the stories (in Bengali) that his photos want to share.
