Tyler is an ARC DECRA Fellow and Senior Lecturer at the Institute for Marine and Antarctic Studies (IMAS) at the University of Tasmania (UTAS). He co-leads the marine CO₂ Removal (mCDR) research program within the Future Oceans Centre of Excellence. He is broadly interested in the marine carbon cycle and its interactions with global climate. His work spans topics across marine biogeochemistry, physical oceanography, Earth system modelling, and policy to unravel the connections between the ocean, our climate, and how society might grapple with, or even augment, the powerful connections between the two.

Role within ARVO: Water-column in-situ measurements lead. Tyler will construct theoretical budgets for alkalinity and carbon across various domains, then assess what observational techniques the team can use to directly measure or infer each term in the budgets. He will coordinate across the voyage specialists to ensure the necessary measurements are being made at sea. Closing these budgets and quantifying their uncertainty margin will help the team understand how efficiently added alkaline material can store carbon in the ocean.
