🔵 my thing

I am an applied mathematician interested in numerical modelling, non-linear inverse problems & optimization methods. My main focus is developing new high-resolution exploration-geophysics methods.

I am currently a computational geophysicist at Seequent. Before that I was a post-doc fellow at Aarhus University in the Hydro-Geophysics Group working on remmediation monitoring, and before that I was a post-doc fellow at Colorado School of Mines in the Geophysics Department working on joint-multiphysics, high-resolution inversions.

I have a Bachelors & Masters in Mathematics, and a PhD in Geophysics. Read more about it in my curriculum vitae.

Broadly, I like making things more efficient and less costly by exploting combinatorial structures and/or discretized continuous spaces.

📡 imaging the subsurface

My PhD was about ground penetrating radar and DC electrical resistivity high resolution joint inversion - code, webpage

High-resolution non-invasive electrical methods for imaging the shallow subsurface are beneficial for Humanity. They shed light on subsurface energy resources (i.e. oil, gas, geothermal), monitor CO₂ sequestration sites and understand ground-water flow.

📺 media coverage

Here is a radio interview about finding graves at the Old Idaho Penitentiary, which is also covered here and here.

Here I talk about how you don’t need to know about rocks to do geophysics.
