Education

  1. B.S. Civil Engineering, Rutgers University, May 2007

Research Interests

My research interests center around the fate, transport, and impacts of emerging contaminants. We conduct extensive field work to quantify the occurrence of pharmaceuticals and personal care products in the environment and to understand how natural processes and anthropogenic activities influence their presence in aquatic ecosystems. In particular, we are interested in understanding how these contaminants may impact sensitive aquatic ecosystems. We also study the ability of wastewater and drinking water treatment plants to remove these contaminants. Finally, we seek to leverage the knowledge we gain from our field studies to design and test methods to reduce the presence and impact of these contaminants in surface and groundwater bodies.

Courses

I teach the following courses every fall semester:
  • ASM (ERM) 309 Measurement & Monitoring of Hydrologic Systems (3)
  • BE 467 Design of Stormwater and Erosion Control Facilities (3)
For information about courses please visit the LionPATH Course Catalog.

EDC Footprint Calculator

Products we use in our everyday lives can be a source of endocrine disrupting chemicals in the environment. Access our Endocrine Disrupting Compounds Footprint Calculator to estimate the amount of EDCs in your personal care and household products. You can watch a webinar on the topic, too!
