Dr. Jeremy McCormack

Research Interests

Jeremy McCormack is a geoscientist specialising on geochemical tracers in carbonate and bioapatite to reconstruct the environment and climate of the past and the ecology of extant and ancient organisms. One focus of Jeremy’s research is the use of carbon and oxygen stable isotopes in continental carbonates, especially lacustrine carbonates, as proxies of past climate and lake hydrology. Jeremy investigated the strengths and limitations of various lake carbonate components (biogenic and inorganic) and mineral phases (aragonite, calcite, dolomite) as palaeoenvironmental proxies. 

Currently, Jeremy is using multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS) analysis to investigate stable zinc isotopes in bioapatite as a dietary and trophic level proxy. Non-traditional isotopes such as zinc offer significant advantages for archaeological, ecological and palaeontological research being potentially diagenetically more resistant and metabolically independent from the traditional nitrogen isotope proxy in collagen.
