A B O U T
Welcome! I am a sedimentologist and field geologist interested in how Earth's sedimentary systems, marine oxygen levels, and life (microbes, animals, and plants) have co-evolved through time. I integrate sedimentology, stratigraphy, geobiology, and geochemistry in my research.
​
I am currently a Leverhulme Trust Early Career Fellow at the University of Cambridge. My research examines vegetated coastlines before angiosperms. How long have coasts been vegetated by salt-tolerant vegetation, and which plants? Then, I will analyse the impact of these ecosystems on the Earth System. For example, through regulating climate (blue carbon storage), as ecological bridges between land and sea, and as hotspots of biodiversity.
​
Prior to my fellowship, I was a Post Doctoral Research Associate at Cambridge with Alex Liu. This research is focused on the sedimentology and environmental context of the Ediacaran biota– Earth's earliest animals.
​
My PhD at the University of Melbourne was supervised by Malcolm Wallace and Ashleigh Hood. This research focused on shallow marine sedimentology and links between environment and ocean oxygenation in Precambrian oceans. I worked on a variety of Neoproterozoic reefs and tidal environments to better understand nearshore processes and sedimentation before the evolution of plants and bioturbation.
​
Prior to my PhD, I was a research associate in the Yale Metal Geochemistry Group working with Noah Planavsky on Precambrian ocean oxygenation. I completed a MSc at the University of Oregon with Rebecca Dorsey and a BA at Colorado College in Geology.
