Research Themes and Scholarly Interests

The project I am currently involved in is known as ‘PROjecTing sEa-level rise: from iCe sheets to local implicaTions (PROTECT)’. The research involves the Investigation of the potential future sea level contribution of the Antarctic Ice Sheet.  The main aim of the work is to improve the representation of ice-sheet-ocean interactions in the coupled models that are used to project future ice sheet evolution. This involves development, implementation and evaluation of algorithms that facilitate the passing of key variables between the ocean and ice sheet component models. 

My other research interests are the future of Deep Meridional Overturning Circulations (MOCs) and El Niño Southern Oscillations (ENSO) in a warming climate. I am also interested in regional climate impact assessment studies.

I, Me, Myself

I started my career as a Structural Engineer (Bachelors in Civil Engineering) and later, I did a Masters in Offshore Structures. My master’s thesis was on ship dynamics and that's how I started exploring the possibilities of scientific programming (C, Maltab and Python) and simulations. I was fortunate to have used it for various projects such as ship traffic simulations; cyclone genesis and track generation; conceptual design of ships etc. While working in a Marine consultancy firm, I had the opportunity to be involved in diverse projects (field work to design and estimation) such as port planning, environmental impacts assessment studies and coastal modelling (Storm Surge, Tsunami). That's how I realised that exploring new areas and learning are not really bad things to do. Hence, the decision to do a PhD in Climate Science was quite easy. In between, I also had the opportunity to teach C programming to undergrad students for a semester. Recently, just like everyone else on this planet, I also have explored Machine/Deep Learning and I just hope that it will come handy one day. In short, I  am all ears when the discussion is on science/engineering.
