Arya Assadi Langroudi

Programme Leader and  Senior Lecturer in Geotechnical Engineering

<br>

I am Leader for the Civil Engineering BSc Hons degree programme, Senior Lecturer in Geotechnical Engineering and fellow of the Royal Society (BS MSc PhD GMICE FGS AFHE >20 papers, >80 citation, >£150k grants). I lead the UG Geotechnical residential field courses, am Academic Lead for Soil Mechanics laboratories and Learning & Teaching Champion for Innovative Practices. My main stream research is centred around implications of micro-mechanics in understanding emerging geohazards (aging, fatigue, saltation, silicatization and mineral dissolution), with a vision to develop decision-support systems (what-if-analysis) and multifunctional ground improvement techniques. I am Principal Investigator for DST-NRF Newton SAFE (2017-18) and the RAE Industry Academia Partnership TASMIP projects (2018-20).

    I am a graduate of the University of Birmingham, bringing >5 years of consultancy experience predominantly gained in tunnel/deep-basement design. I was granted a PhD in 2014 for research on the micromechanics of collapse in loess. My research led to a 2-year secondment at Atkins, in 2012, where I worked towards the engineering of calcareous collapsing soils into embankments within the scopes of CEN/TC 396. This led to my joining Newcastle University as a research associate and then lecturer where I researched into urban ground improvement decision-support systems and led the Ground Improvement Technologies block CPD/MSc course. I joined the University of East London in 2015. I have published on micromechanics (mineral dissolution, clastic/fractal properties of particles, inter-particle forces, structure-based constitutive models and double-porosity concept). I have also published on computer-aided analysis of excavations (RSFEM, DE-FD programming) and cavity stability. I sit on the editorial board for a number of journals and Engineering Framework Review panel of a number of UK universities.

    Overview

    The Emerging Urban Geohazards (EUG)

    The past 10 years have seen a steep rise in the number of fatalities and extent of economic losses stemmed from emerging ground-related hazards (e.g. sinkholes) particularly in urban areas. Geo-hazards are interconnected, continuously and globally strike cities on a worryingly escalating scale, claim lives, and demolish infrastructure.
    My research is centred on such modern hazards (e.g. aging and fatigue in soil, urban aerosols and air pollution, urban sinkholes and ground collapse and extreme climates), their interconnectivity and mechanisms of occurrence, methods for effective early detection and preventive/corrective measures. Primarily this is achieved through studying the mechanisms of hazards at micro-scale and developing macro-scale cross-disciplinary solutions (e.g. biologically inspired self-healing technologies). The research offers the earthwork and construction industry tools to detect early cases of hazards, offers simple decision-support useful in the less-developed slimly-resourced far flung, and alternative preventive/corrective measures tailored to problem and location.
