Primary research fields include
Groundwater hydrology, groundwater-surface water interaction and application of environmental tracers.
Research topics of special interest have included:
assessment of recharge to aquifers
assessment of potential risk of groundwater contamination
estimate of groundwater flow rates
groundwater flow and solute transport in river basin and unban water supply sites
surface water - groundwater interaction
application of groundwater dating tools(CFCs, C-14 etc.)
