about

I am a Ph.D. candidate at University of Maryland, Baltimore County (UMBC) in the Environmental Engineering program within the department of Chemical, Biochemical and Environmental Engineering (CBEE). My graduate advisor is Dr. Claire Welty. I was an IGERT trainee at the Center for Urban Environmental Research and Education (CUERE). I graduated with an Sc.B. in Environmental Geology-Physics/Math from Brown University in 2008.

current projects 

  • I am looking at the effects of urbanization (impervious surface cover, decreased ET, and groundwater export to wastewater systems as I&I) on groundwater recharge and baseflow in the Baltimore region.  I am using ParFlow to model coupled surface and subsurface flow. This work is part of a NSF Coupled Human-Natural Systems project investigating the feedbacks between water availability and development. 
  • I am interested in the stormflow generation mechanisms which lead to the the wide range of pre-event water proportion we see in urban watersheds using chemical hydrograph separation.  Through analysis of Baltimore Ecosystem Study LTER records and numerical experiments, I am working to better understand the controls on and relationship between pre-event water proportion and watershed storage.

  •  Land Cover Variability and Water Resources in Spring Valley, Nevada
    • Senior Undergraduate Thesis Research at Brown University. 2008. Advisor: Dr. John Mustard
    • Abstract: Spring Valley in Eastern Nevada is part of the Southern Nevada Water Authority’s Groundwater Development Project. Tens of thousands of acre-ft of groundwater per year will be pumped out of Spring Valley for use in Las Vegas Valley. Understanding the pumping’s impacts on Spring Valley ecosystem goods and services is important for rational water management. This project seeks to contribute to a scientific understanding of vegetation in Spring Valley for potential use in informing vegetation monitoring. This work defines baseline vegetation abundance and variability as indicated by the Normalized Difference Vegetation Index (NDVI) from Landsat data of June 1991, 2000, 2002, 2004 and 2007. A vegetation response classification was created where the sensitive classes are identified. Vegetation greenness over these 5 years, as indicated by NDVI, does not correlate either with precipitation or groundwater variability. Large changes in the water table could trigger changes in NDVI which are easily flagged, and thus remotely sensed data could be an important tool to monitor potential future vegetation changes in Spring Valley.
