Dr. Lahr is committed to students and education, passionate about research in environmental chemistry, motivated by service and outreach, and determined to protect drinking water supplies from the pressures of climate change, population growth, and resource extraction. Her research targets the need for detection, monitoring, and prevention of environmental pollution, with a focus on developing sensors for environmental pollutants, monitoring concentrations of environmental contaminants, examining processes involved in pollutant degradation, conducting mass balances concerning contaminant source and fate in the environment, and ultimately sharing scientific data to encourage sustainable-minded decision making. As the population of the Earth edges closer to its estimated carrying capacity, preservation and management of natural resources is becoming increasingly important to maintain public health.

Recent Research:

  • Production of fertilizer from source-separated urine and evaluation of the fate of contaminants (bacteria, virus, antibiotic resistance genes, and pharmaceuticals)
  • Analytical method development for harmful algal toxins
  • Drop coating deposition Raman spectroscopy (DCDR) and surface-enhanced Raman spectroscopy (SERS) for environmental analyses
  • Nanoparticle transport in microfluidic paper-based analytical devices (µPADs)
  • Gold nanoparticle production by algae
