About Me

I am a PhD candidate primarily interested in the adaptation and acclimatization of corals to climate change. Specifically, I use molecular techniques to better understand corals and their microbiomes in the face of environmental change, and to inform the development of novel and innovative reef restoration techniques. I am based at both the ARC CoE for Coral Reef Studies at James Cook University and the Australian Institute of Marine Science, as part of the joint venture AIMS@JCU.

Hailing from the rocky shores of California, I began my career in marine science at the University of St Andrews, Scotland, after which I completed my Bachelor of Marine Science with 1^st Class Honours at James Cook University. My early research was in the field of ecotoxicology, determining the biomonitoring potential of jellyfish for heavy metal pollution. I then switched gears to molecular phylogenetics while working as a research volunteer at the California Academy of Sciences in San Francisco with Dr. Terry Gosliner and Dr. Rebecca Johnson on nudibranch (sea slug) taxonomy and systematics. My interest in molecular work drove me to continue into molecular ecology for my PhD, particularly on the microbial ecology of corals. I am now carrying out my PhD under the supervision of Prof. Madeleine van Oppen, Prof. Philip Munday and Dr. Gergely Torda.

Current Research

My PhD research is focused on understanding the drivers of healthy coral microbiomes (e.g., whether microbial community composition is driven by factors such as host species, season and/or environment) and how we can use this information to inform the development of microbiome engineering techniques that may enhance climate resilience in corals. Microbiome engineering is the manipulation of microbial communities for improved host performance. This research sits under the coral assisted evolution umbrella, a novel restoration concept aimed at human-assisted enhancement of coral survival under environmental stress. As such, I am part of an international collaborative team researching assisted evolution approaches that is led by Prof. Madeleine van Oppen at the Australian Institute of Marine Science and Dr. Ruth Gates at the Hawai’i Institute of Marine Biology.
