I have conducted research with over 60 undergraduate students at Temple University. I have collected photos back to 2016, but hope to be adding more as I hunt through my files!
SPRING/FALL 2025
Lucas Oberholtzer Hess: Lucas is analyzing stream temperature data and doing some geophysical monitoring
SUMMER/FALL 2024/ SPRING 2025
Lucas Vito, Ryan Frederiks (postdoc), Katie Alexandrenko, and me sampling a spring in Pennypack Park
Lucas is working on the I95 project, and Katie has been sampling for the Urban Critical zone project and completing chemical analysis for the area watersheds associated with a William Penn Foundation grant and a Velay Summer Fellowship.
