Overview
I am a Professor of Water and Environmental Engineering and the Director of International at School of Engineering, Cardiff University. I have more than 20 year's experience in developing and refining hydro-environmental computational models to investigate hydrodynamic, environmental challenges, flood and water quality modelling, as well as sustainability and resilient solutions.
I also serve as Co-Chair of the IAHR 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.
In my capacity as the Director of International and Engagement for the School of Engineering at Cardiff University, 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 main strands of my work are:
· Water Quality and Hydroepidemiology: Hydro-environmental modelling of fate and transport of water quality indicators, including nutrients and emerging contaminants such as microplastics, as well as microbial water quality and its application to hydroepidemiology.
· Flood Risk Management and Resilience: Flood modelling, including flash floods and dynamically linking models; Sustainable Drainage Systems (SuDS); flood hazard and risk assessment; evacuation planning; and approaches to strengthening resilience to flooding.
· Digital and Data Driven Hydro-environmental Modelling: Digital twins of the environment and the integration of monitoring, data driven approaches and hydro-environmental modelling to improve understanding, prediction and management of environmental systems.
· Marine and Riverine Renewable Energy: Tidal range schemes, and tidal and riverine turbines, with particular emphasis on resource assessment, optimisation, hydro-environmental impact assessment, and the development of sustainable, low carbon approaches to renewable energy generation.
· Global Water Security and Climate Resilience: Interdisciplinary research addressing global water security challenges and the resilience of water systems to climate change, integrating engineering with environmental, social and economic perspectives.

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.
