Geophysical data visualisation
Used GMT and shell scripting to combine gravity, seismic velocity and spatial data into a single crustal interpretation; awarded 95%.
I am Harry O'Sullivan, a geophysicist turned mining-technology builder based in Perth, Western Australia.
I graduated from Durham University with a first-class degree in Geophysics with Geology. What I enjoyed most was using messy, geoscienctific data to build an interpretation: writing scripts, combining spatial datasets, testing models and deciding what the evidence supported. I moved to Perth in March 2023 to work as a FIFO Geologist with Fortescue.
Since moving into mining, my curiosity has expanded beyond geophysics. I continually pick up new skills in Python, GIS, SQL, Snowflake, machine learning, generative AI and product development and do so to solve real operational challenges.
I am still early in my career. I learn fastest by building: I start with a rough prototype, put it in front of users and engage directly with stakeholders to gauge what works, and what needs improvement.
Used GMT and shell scripting to combine gravity, seismic velocity and spatial data into a single crustal interpretation; awarded 95%.
Mapped seismicity, faults, GPS velocities, strain rate and seismic moment to explore how the plateau is deforming.
Used forward gravity modelling, bathymetry and magnetic data to investigate how an oceanic plate bends beneath a Hawaiian seamount.
Analysed CO₂ proxies and oxygen-isotope records to explore changing climate sensitivity through the past 67 million years.
Studied long-runout underwater sediment flows and translated the analysis into practical recommendations for subsea cable risk.
I am a keen and varied reader.
How the World Really Works

Superforcasting
I want to help change how the mining industry plans, learns and makes decisions. Mining has difficult physical constraints, fragmented data, deep specialist knowledge and a huge number of workflows that still depend on manual interpretation. That makes it a hard place to build technology — and a very worthwhile one.
My interests sit where geoscience, software, spatial data and AI meet. Long term, I would like to build products that make complex operational decisions clearer, faster and more measurable, and potentially build a company around one of those stubborn problems.
This website is my working record: projects I have built, ideas I am testing and things I am still learning.
