Overview
I am a Professor of Water and Environmental Engineering and the Director of International at School of Engineering, Cardiff University. I have circa 20 year's experience in developing and refining hydro-environmental computational models to investigate hydrodynamic, flood modelling as well as simulating water quality and sediment transport processes.
I also serve as Co-Chair of the International Association for Hydro-environment engineering and Research Technical Committee on Global Water Security, which focuses on reflecting the interconnected nature of global water systems and the challenges of managing water quality and security worldwide through advancing understanding of water flow, sediment transport, and pollutant dynamics across catchments, rivers, urban systems, estuaries, and coastal waters. I am the past Chair and member of the leadership team of the IAHR UK chapter.
In addition, I am Director of International and Engagement for the School of Engineering at Cardiff University, where I develop links and strengthen collaborations in research and education between the School and its international partners.
My research focuses on hydro-environmental modelling, driven by the goal of reducing risks to human health and promoting the sustainable use of water resources. The three main strands of my work are:
• Flood Modelling:
Specialising in developing process-based and data driven models to reduce flood risk, flash floods simulation, dynamic 1D–2D flood model coupling, flood risk and hazard assessment, evacuation planning and the implementation of Natural Flood Management (NFM) strategies and particularly Sustainable Drainage Systems (SuDS).
• Water Quality and Sediment Transport:
Modelling range of water quality parameters, including nutrients, faecal bacteria, sediment and emerging contaminants such as PFAs. My main focus is on enhancing the representation of physical processes such interactions with sediments and dynamic decay rates, as well as developing AI-based early warning systems for water quality assessment, and compliance monitoring for bathing waters and aquaculture sites.
• Marine and RiverineRenewable Energy:
Marine and riverine renewable energy including small hydro-power, tidal stream and tidal range schemes. This includes resource and hydro-environmental impact assessment, optimisation of the schemes, wider benefits such as energy storage systems and developing a resilient turbine for off-grid utilisation.
I am an associate editor of the International Journal of River Basin Management and was the Co-Editor-in-Chief of Proceedings of the Institution of Civil Engineers - Water Management. I also led one of the School's Impact Case Study in REF2021 focused on flood risk management and hydro-epidemiological modelling strategies.

Research
My research focuses on hydro-environmental modelling, driven by the goal of reducing risks to human health and promoting the sustainable use of water resources. The three main strands of my work are:
• Flood Modelling: Specialising in developing process-based and data driven models to reduce flood risk, flash floods simulation, dynamic 1D–2D flood model coupling, flood risk and hazard assessment, evacuation planning and the implementation of Natural Flood Management (NFM) strategies and particularly Sustainable Drainage Systems (SuDS).
• Water Quality and Sediment Transport: Modelling range of water quality parameters, including nutrients, faecal bacteria, sediment and emerging contaminants such as PFAs. My main focus is on enhancing the representation of physical processes such interactions with sediments and dynamic decay rates, as well as developing AI-based early warning systems for water quality assessment, and compliance monitoring for bathing waters and aquaculture sites.
• Marine and Riverine Renewable Energy: Marine and riverine renewable energy including small hydro-power, tidal stream and tidal range schemes. This includes resource and hydro-environmental impact assessment, optimisation of the schemes, wider benefits such as energy storage systems and developing a resilient turbine for off-grid utilisation.

Biography:
I graduated from Amirkabir University of Technology - Tehran Polytechnic (Iran), with a BSc in Civil Engineering in 2001 and an MSc in Water Engineering in 2005. I also worked as a civil engineering at different levels, before I started my PhD including during my under graduate and masters studies.
My PhD research was focused on improving various 1D and 2D hydro-environmental numerical models through enhancement of boundary conditions, increasing model efficiency, linking model applications compliance with OpenMI standard, development of a user-friendly graphical user interface and incorporating numerical models into a GIS software beside refinements of models using laboratory data. Through a Halcrow (now Jacobs) studentship, I was also in development of ISIS 2D and linking of the model to ISIS 1D (both are components of Flood Modeller Pro now).
I worked as research associate at Cardiff University from Feb 2010 to Sep 2013, working on two different projects simultaneously. One of the projects involved developing hydro-environmental models to predict water quality at a pilot site, namely Swansea Bay, and providing a better understanding of pollution sources, to assist with maintaining UK’s Blue Flag beaches by meeting the new EU Bathing Water Directive. The other project involved developing hydro-environmental models to simulate the hydro-environmental impacts of various marine renewable energy schemes, including tidal stream turbines and tidal range schemes, such as tidal lagoons and barrages.
