Ravat, Dhananjay

Computational geophysicist; dealing with large planetary data sets and inverse problems.

Proposal to NASA to handle magnetic data around the world from the European Space Agencies Swarm mission done on the DLX.

Working to derive the global lunar and Mars magnetic field models through memory and time-intensive (they run for a couple of weeks) geophysical inversions for my lunar and Mars geophysical research grants without the UK CCS/HPC.  I have been running these computations for the last 2-3 years.  With the current and planned improvements, I hope to be able to solve problems that require more memory and speed and generate higher resolution global models of the lunar and Mars magnetic field.. I really appreciate the support and guidance the facility and people provide and the improvements being implemented.
