Gawsia Wahidunnessa Chowdhury, an academician and researcher. She received her PhD in Zoology (wetland ecology) from the University of Cambridge and is a published author. She has more than 14 years of experience in teaching animal diversity, wetland ecology and relevant topics in zoology. She has received many awards and grants, including a Commonwealth Academic Staff Scholarship and a Wildlife Conservation Society Fellowship. Dr Chowdhury works with government, non-government and international organizations, and is currently working with threatened species and habitat conservation in Bangladesh. In addition to being a board member of the international conservation organization WildTeam, life member, Zoological Society of Bangladesh, she has also been appointed as the regional co-chair of South Asian Invertebrate Specialist Group. She is also a member of international technical groups including the Commission on Education and Communication and the Species Survival Commission of the International Union for Conservation of Nature. She has successfully completed National Geographic Society’s Sea to Source Ganges River Expedition and led the Bangladesh team. Gawsia received the OWSD-Elsevier Foundation Awards 2022 (2022 OWSD-Elsevier Foundation Award winners announced | OWSD) for Early Career Women Scientists and she is committed to continue her work to conserve aquatic systems and threatened species of Bangladesh.Read less

|Heavy metal pollution||
Accumulation of heavy metals in different fish species has been recognized as a threath from different research projects.
National Geographic Society's Explorer 2019 and team leader (Bangladesh) -Sea to Source: Ganges Expeditions 2019. During the portion of the expedition along the Ganges River in India and Bangladesh, we achieved many scientific objectives in the fields of environmental science, citizen science, community engagement, and conservation technology.
Received training on conservation education by the Wildlife Conservation Society, New York, USA. Designed and implemented active learning based different education programs and materials for threatened species conservation (e.g. Teachers for Planet Earth sponsored by National Geographic Society; Teachers for Tigers sponsored by WCS, USA
Freshwater mussels (Unionida) are globally endangered but perform crucial ecosystem services. Their status and role in tropical regions are poorly understood, resulting in a nearly complete lack of effort toward their conservation. Understanding mussel functions in developing countries is particularly important because costly interventions to restore habitat functionality are often infeasible. As part of my PhD project, I investigated the role of mussels as 'ecosystem engineer'.
Biological measures were used to assess the aquatic ecosystem health of selected lakes of Bangladesh using 'macroinvertebrates'. Biotic index called 'BLBI' has been developed.
|Fisheries as source of plastic pollution||
Riverine plastic pollution from fisheries has been reported from the Ganges river system. We have been planning to continue research in relevant field.
