Amir Alizadehshiraz

I am a PhD researcher in Mechanical Engineering at the Universitat Politècnica de Catalunya, with a background in Civil Engineering, and a simulation engineer at AV Enginyers.

My research concerns structural dynamics, specifically ground-borne and building vibration generated by railways, road traffic, and human activity, along with the re-radiated noise it produces indoors. These are problems where the physics is genuinely hard. Energy radiates through an unbounded soil domain, couples into structures with their own dynamic character, and the result has to be predicted accurately enough to inform real design decisions before anything is built.

I work on the numerical methods that make those predictions tractable: coupled finite element and boundary type formulations, and models of soil-structure and structure-soil-structure interaction. Increasingly I also apply machine learning and uncertainty quantification to problems where classical simulation is too slow, or where the honest answer is a distribution rather than a single number.

Working simultaneously in academia and industry keeps both halves honest. The research gives the engineering work a rigorous foundation, and the engineering work keeps the research pointed at questions that matter to the people who build things.
