Teaching Interests

My teaching centers on helping students understand how our environment shapes daily life and how our choices, in turn, shape the environment. I’m especially interested in the health of urban ecosystems, where water, air, and soil quality directly affect communities.

I enjoy teaching courses that help students explore how environmental systems function and change over time. Whether we’re discussing natural processes, human impacts, or ways to build more resilient communities, I aim to make complex ideas accessible and relevant. My goal is to help students recognize that environmental science is everywhere – it’s woven into the places we live, work, and play.

I love getting students outside to investigate the world firsthand. Whether we’re in regional parks, knee-deep in local streams, or even underground, fieldwork gives my students the chance to observe real processes and discover the environment in a way no classroom lecture can match.

Research and Scholarship

Collaboration has always been at the heart of my research. I’m most energized working with others to understand how human activities shape the health of ecosystems. I began my career studying marine and estuarine environments, where I learned how easily contaminants move through water and accumulate in unexpected places.

In graduate school, I collaborated with the National Marine Mammal Stranding Network and the National Institute of Standards and Technology. Our team analyzed tissues from several dolphin species to detect persistent organic pollutants. Seeing pesticides and flame retardants in open-ocean predators made it clear how deeply human choices ripple through natural systems.


Post-grad, I joined the multi-disciplinary Land Use Coastal-Ecosystem Study (LU-CES). Our lab examined how microorganisms respond to nutrient loading in estuaries bordered by golf courses and residential developments. This work strengthened my interest in the connections between land use, water quality, and ecosystem function.


At Muhlenberg, my research is rooted in the place I live. I collaborate with Dr. Iyengar (Biology) and the City of Allentown to study local stream health. This project brings together students, faculty, and community partners to understand how everyday decisions on our lawns, streets, and parks shape the waterways that flow through our neighborhoods.
