Introduction
With a wide interest in biology, agri & environ sciences, opportunities are created & these require multi-disciplinary & nature-based solutions to solve them. I am keen about hormones, plant adaptations, biostimulants, defined organics (frass, vermicompost, compost), soil-microbe-plant interactions, analytical biochem; for circular bioeconomy, bioremediation (mine sites, pollution, degraded land), conservation & ecosystem restoration (e.g. mangroves, forests) projects are of interest to my team.

When you eat rice with fish – or rice with crab or shrimp – you probably do not think about where the food came from. And if you do, you probably think that the rice grew in a paddy field, while the fish, crab or shrimp were caught in the sea. However, this may only be partially true. Systems for growing rice and various aquatic animals together ha...
