Research Overview and Current Projects

Laura’s is interested in the effects of the devastating disease chytridiomycosis, caused by the fungal pathogenBatrachochytrium dendrobatidis, Bd, on population persistence in amphibian species.  She is interested in how animals cope with and continue to persist in the face of devastating disease.  Her DECRA project at the University of Melbourne focuses on one mechanism of population persistence: increased reproductive effort.  Her current research is focused on investigating the effects that disease has on reproduction. She aims to use the knowledge from her field work and experiments to improve conservation efforts for amphibians.

Background

Laura received her a Bachelor of Arts in anthropology and Bachelor of Science in ecology and evolutionary biology from Tulane University in New Orleans, Louisiana in 2010. She went on to complete her Masters of Science in environmental biology from Tulane University in 2011 where she participated in a number of amphibian projects including clinical chemotherapy trials for treating Bd, studying non-amphibian hosts of the amphibian chytrid fungus, quantifying sub-lethal effects of disease, and determining best practice methods for marking amphibians.

Laura received her PhD at James Cook University in Townsville, Queensland Australia in 2016. For her PhD research she explored the interactions between frogs, disease, and the management of critically endangered species. She explored pathogenesis of disease on understudied and endangered species, as well as determining mechanisms of population persistence. She hopes to be able to directly use the information generated from her research to further conservation efforts to protect Australia’s declining frog species.

Laura was a post doctoral research fellow from 2016-2018 at the University of Pittsburgh with Dr. Corinne Richards-Zawacki.  Her research there focused on the effects of climate change on amphibian species and communities, specifically investigating the effects of pond drying on the amphibian immune system and physiology.  She also explored disease dynamics in local amphibian populations through different sites and seasons in an effort to help predict impacts of disease on populations in the face of a changing environment.
