If it involves geochemistry (and all important Earth processes do), then we’re interested. Geochemistry allows us to go beyond what a geologic feature looks like and answer the “origins” questions: what is it made of, where did it come from, when did it form, how long did it take, and why is it here?
We use major and trace elements, stable and radiogenic isotopes, experiments and theory. We emphasize making measurements in laboratories at Otago because it allows us to learn from our mistakes and innovate.
The work is challenging, but it’s also a lot of fun. To be successful, you need to be a keen observer with a creative imagination (geologist: tick) and an appreciation of chemistry, maths and physics. If this describes you (or someone you’d like to become), then please consider doing postgraduate research with us.
