The Hind Rattan is one of the highest Indian diasporic awards granted annually to non-resident Indian citizens (NRIs) by the NRI Welfare Society of India.

Dr Vishwakarma’s most recent research focuses on understanding various physical processes that drive contemporary sea level rise, using Gravity Recovery and Climate Experiment (GRACE) satellite data to estimate water mass change in river basins and ice-sheets. In his PhD he developed data processing methods to minimise signal damage (leakage and attenuation) due to filtering of noisy GRACE satellite data.

Dr Vishwakarma has been invited to receive his award at the 39th International Convention of NRIs in New Delhi on 25 January.
