My doctoral work at Nagasaki University Japan was on aspects of the early life history processes in two intertidal macrobenthic species with the contrasting mode of larval development in coastal waters of western Kyushu, Japan: the callianassid shrimp, Nihonotrypaea harmandi (Bouvier, 1901), and the trochid gastropod, Umbonium moniliferum (Lamarck, 1822). I also worked as a teaching assistant during my doctorate period at the Faculty of Fisheries and took classes for graduate and undergraduate students. After completing my doctorate degree I joined at National Institute of Oceanography, Goa (CSIR-NIO) as a Project Associate in the project Ballast Water Management Programme in India. In 2011, I received DST Fast Track Project for Young Scientists and continued to work at NIO as a Principal Investigator before joining Presidency University in 2012.

Most of the marine benthic macroinvertebrates have bipartite life history, a dispersing planktonic larval stage that spends some time (depending on the species and type of larval development) in the pelagic realm, before returning to the benthic environment. By studying one phase of this lifecycle, it is virtually impossible to conclude about their population dynamics. So it is imperative to know the events starting from spawning and release of propagules (i.e. gametes/larvae) by adults, larval dispersal, to recruitment and survival after settlement. For benthic invertebrates, the first few months or even days after settlement are considered the most vulnerable period. The transition between the habitats prior to the adult stage includes many important but poorly known events in their life histories. The ‘benthic-pelagic linking’ approach is lacking in most routine benthic or planktonic studies. Therefore, from an ecological perspective, filling the gap between pre-and post settlement events is essential to gain a comprehensive picture. I am interested in understanding the relative importance of pre- versus post-settlement events in soft-bottom communities, integrating both pelagic and benthic phases of some benthic animal’s life cycles. Hence, my research involves a blend of benthic and plankton ecology.

Recently my laboratory is working on the impact of anthropogenic perturbation like ocean acidification and elevated temperature on the physiological energetics of shellfish resources of West Bengal through mesocosm experiments.

My teaching interests include - animal diversity: Non-chordate and Chordate, animal reproduction, physiology, marine biology- plankton and benthic ecology, marine invertebrate larval ecology, developmental biology, ecology, conservation biology, fishery resource management, and aquaculture.
