Welcome to this webpage and thank you for visiting.

Our research group studies hydrologic flow and transport processes. We pursue basic knowledge and the development of solutions to environmental and societal water issues. We are motivated by problems that cross disciplinary boundaries. This requires drawing ideas and techniques from different fields. Thus, we apply various approaches including conventional hydrologic and water quality monitoring, geophysical surveys, remote-sensing, analogue experiments, and mathematical modeling including theoretical methods and computational simulations.

Examples of recent research topics include: groundwater-surface water interactions and associated nutrient transport and transformation, coastal hydrogeology and submarine groundwater discharge, ecohydrology of semi-arid and temperate biomes, pore scale flow and transport phenomena, flow and transport in fractures, energy balance and thermal regime of aquatic systems, hydrogeology of springs, and hydrogeologic processes in cold regions.

If you are passionate about water and the environment, independent, hard-working, possess a 'can do' attitude, and have a strong interest in addressing fundamental problems with direct applications to relevant issues, you will fit in well in our group. Please feel free to contact us if you are interested in joining or collaborating with our group.

My primary focus is unraveling the intricacies of flow and reactive transport in the subsurface. My research aims to contribute solutions to the escalating global drinking water crisis caused by groundwater contamination. To achieve this, I am committed to developing robust models that can effectively explain the complexities of transport phenomena in the subsurface, particularly within the critical zone. I...

With increasing concerns on global climate change, there has been a growing interest in the potential impacts of it to groundwater reservoirs along with the surface waters. My principal research interest is based on the interaction between these major reservoirs in regional and local scales with the emphasis on water balance, saltwater intrusion, and climate variability. Use of field observations,...
