Langroudi

I turn operational data from ageing infrastructure into decisions about what to repair, replace, or leave alone — combining machine learning, physical simulation and materials analysis. Proven on district heating networks; the methods travel.

01 — The path

How far a training can travel

I trained as an architect. I now build models that predict when buried infrastructure will fail. The distance between those two is the point — and an interdisciplinary education is what made it crossable.

  1. 2007–2012

    Architectural Engineering

    Bachelor

    Where I learned to design physical things that have to work — materials, loads, and the distance between a drawing and what actually gets built.

  2. 2014–2016

    Architecture

    Master, abroad

    I moved to continue in the same discipline and go deeper into it.

  3. 2016–2019

    REAP

    Master, interdisciplinary

    Resource Efficiency in Architecture and Planning — interdisciplinary by design, and the turning point. This is where I understood that what I had learned could be carried much further than the field it came from.

  4. 2019 – now

    Where that took me

    Far transfer, applied

    Infrastructure engineering. System reliability. Laboratory methods never used this way before. Machine learning. Different fields — the same training, carried across.

None of it was only study. There was work beside every stage — drafting, then three years in an architecture practice, then an internship abroad during the master's, then building the software that runs laboratory equipment.

Far transfer is the thread. Each step carried the one before it into a field it was not built for — which is why measuring pipe density with X-ray microscopy, or turning laser spectroscopy on polyurethane foam, was the obvious move rather than a leap.

02 — About

What I do

I work where data science meets physical infrastructure. My research builds predictive maintenance and asset management methods: models that estimate how far a buried, hard-to-inspect asset has moved through its service life, and frameworks that turn that estimate into a defensible decision about intervention.

The work runs the whole chain — instrumenting lab experiments and writing the software that drives them, characterising material ageing by spectroscopy and X-ray microscopy, simulating thermal and mechanical loading history, and training models on years of operational time-series data.

A recurring thread is taking measurement techniques to problems they have not been used for. I brought X-ray microscopy, laser-induced breakdown spectroscopy and infrared spectroscopy (FT-IR / FT-NIR) to the study of polyurethane foam ageing in pre-insulated pipes — none of which had been applied to this material for this purpose — and developed the processing algorithms myself, because no laboratory software existed that could do the analysis.

District heating networks have been my proving ground. The underlying problem — deciding when ageing assets you cannot easily inspect need attention, and justifying that call with evidence — is common to water, gas, power and transport infrastructure alike.
