Anandaroop Ray
Welcome! I am a statistically minded geophysicist who uses modern optimization algorithms and Bayes' Theorem to make inferences about earth structure.
Most of my work has been with electromagnetic or seismic data, and for the past few years I have extensively been using the numerically focussed and open source Julia language.
Here's a link to the 100% Julia based HiQGA project in which I have used research from almost all the papers underneath.
