Research Associate Earth Sciences

Research and Teaching Interests

My background is in hydrogeology and groundwater modeling. My interests include surface water—groundwater interactions (including study of so called ‘disconnected losing streams’, and using heat as a tracer), and the role of aquifer heterogeneity on solute and thermal transport processes.


I am currently working with A/Prof Laura Lautz’s group, on the NSF funded project “Integrating Research and Education to Advance the Use of Heat as a Tracer of Surface-Ground Water Interaction at Multiple Spatial and Temporal Scales”.


My research at Syracuse is focused on the influence of streambed heterogeneity on the use of temperature time series data to estimate exchange between groundwater and streams. The use of temperature time series data is useful because estimates of flux can be obtained cheaply, easily, and without the need to measure hydraulic conductivity. However, the analytical models used to estimate a flux from temperature data assume that the streambed is homogeneous (which it almost never is).


This research is being carried out through the use of groundwater simulations and synthetic heterogeneous streambeds (where fluxes are ‘known’). Estimates of flux from temperature time series data can be compared to ‘actual’ fluxes to test the validity of analytical models to process temperature data, providing guidance on the accuracy of temperature based methods.
