"Life is nothing but a series of experiences"

Arjun Velliyidathu

I’m a computational geophysicist, which means I spend my days writing code and building numerical models to figure out how the Earth actually works.

Tectonic Tales is a space I created to share my perspectives on Earth's physical systems, discuss the computational tools I build, and occasionally step outside the science to explore broader human experiences — all with the goal of exchanging ideas and getting your thoughts along the way.

Professional Background

Currently, I'm a Project Scientist at the National Centre for Polar and Ocean Research, in Goa. My journey in Earth sciences began with an MSc in Marine Geophysics from Cochin University, which led me to a research role at the Indian Institute of Geomagnetism and eventually to National Geophysical Research Institute, where I did my Ph.D.

While my formal training is in geophysics, my real obsession is with systems. Understanding the underlying architecture of physical, computational, and human environments. Day-to-day, this involves developing numerical models, building geospatial pipelines, and writing open-source workflows to translate raw data into clear insights.

What You Will Find Here

Think of this site as a living logbook of my research, technical builds, and creative writing. You can explore the content across three primary threads:

  • Earth & Geophysical Systems: Investigations into the physical processes governing mountains and oceans — from deep-earth dynamics to near-surface processes.
  • Computation & Tools: Breakdowns of my numerical models, data visualization pipelines, and the open-source tools and workflows I develop for my research.
  • Reflections & Narratives: A collection of personal essays, creative writing, and fiction — attempts to explore order, history, philosophy, and human experience.

Beyond the Lab

Away from the terminal, I am a family man, sharing my life with my wife, Gayathri, and keeping up with our daughter, Nainika. I am also an avid reader, a practitioner of martial arts, and a keen chess player. To me, these are not isolated pursuits separate from my scientific work; they are simply different frameworks for studying complex systems, discipline, and strategy.

Whether you are here for the geoscience, the code, or the stories, I hope you find something of value.
