Biography

Dr. Wasylenki is a biogeochemist investigating metal chemistry in the earth's lithosphere, hydrosphere, and biosphere. Specifically she examines stable isotope fractionation of transition and post-transition metals in order to develop new tools for tracing chemical reactions that involve metals.

Her primary focus is on fundamental, experimental investigations of metal isotope fractionation mechanisms. In the past ten years multi-collector ICP mass spectrometry has led to the discovery that stable isotopes of most metals fractionate in a wide range of environments all over the Earth. The number of published metal isotope analyses is burgeoning rapidly, and the prospect of much new understanding of metal chemistry in nature is exciting. Few investigators, however, have yet attempted to elucidate the mechanisms that drive metal isotope fractionation. Without careful investigation of molecular-scale mechanisms and systematics of metal isotope effects, we cannot hope to interpret robustly the wealth of information available in nature.
