Pakdad Langroudi

Profile

Engineer and researcher working where data science meets physical infrastructure. I develop 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. My work spans the full 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. District heating networks have been the proving ground; the underlying problem of managing ageing, hard-to-inspect assets is common to water, gas, power and transport infrastructure.
