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.
- 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
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
- 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.
