About
Growing up in a rural town in the deltaic plains of Bangladesh, I witnessed the natural world rapidly disappearing under the pressures of population growth and development. Motivated by this experience and a lifelong passion for wildlife, I have spent the past 15 years working in research, conservation and behavioural ecology of globally threatened species in Asia, with a particular focus on threatened birds. My undergraduate training in Environmental Science, followed by MPhil in Conservation Leadership and PhD in Zoology from the University of Cambridge, has strengthened my ability to understand the complex conservation challenges facing threatened species and ecosystems, and to develop science-based solutions through rigorous research.

Research
I am a conservation scientist interested in the ecology and conservation of biodiversity and ecosystems, particularly the impacts of environmental change and human activities on species and habitats. My research combines field ecology, remote sensing and conservation planning to better understand how species respond to habitat loss, climate change and large-scale anthropogenic pressures, with the aim of developing applied solutions to prevent biodiversity loss and species declines. Much of my work focuses on migratory species and wetland ecosystems within the East Asian–Australasian Flyway, including habitat management, spatial prioritisation and conservation under rapid environmental change. Currently, my research aims to improve understanding of the ecological requirements and conservation needs of migratory species across dynamic ecosystems.
