Under the supervision of Dr. Dominique Weis, I am exploring the impacts of environmental pollution using honey bees as bioindicators. Trace element and isotopic fingerprints of honey samples (and other bee products) from the greater Vancouver area can serve as a proxy for chemical snapshots of ~2 km-diameter regions (the range of a typical honey bee). Thus, we can assess small-scale variations in trace elements, and their isotopes, of particular interest to pollution processes.
- Applications for traditional and non-traditional isotope systems: particularly new applications for public health
- Method development for isotopic analysis of environmental and clinical matrices
- Multicollector mass spectrometry (MC-ICP-MS, TIMS)
- Isotope and high temperature geochemistry
- Other/past research interests: igneous petrology, uranium-series geochemistry, and geochronology
