- He was an Associate Editor of Remote Sensing for Ecology and Conservation (Wiley, 2014-2017)
- Shovon is a Member of the GEO Blue Planet WG on EO for Water-Associated Diseases and the GEO-BON WG on Ecosystem Function. He has been an Associate Researcher at Sir Alister Hardy Foundation for Ocean Science (2016)
- Shovon has worked on several research projects and consortiums including: Ocean Colour Climate Change Initiative; Bio-optical modelling using in-situ and remote sensing data for estimating phytoplankton size classes and functional types; Ecosystem model to estimate phytoplankton size spectrum from remotely-sensed ocean colour data; Space-time model of marine primary production using remote-sensing based ocean colour data; Modelling evolutionary food-webs using body size and habitat preference of a species as adaptive traits; Mathematical modelling of marine ecosystems based on field data and remote sensing; Regional-scale primary production and applications to ecosystem dynamics; Mathematical modelling of plankton ecology, population ecology and eco-epidemiology.
- Shovon obtained a BSc (Hons) in Mathematics, an MSc in Applied Mathematics and a PhD in ecological modelling using non-linear dynamics.
