About me

I am currently a PhD student and National Geographic Explorer at the University of Wisconsin-Milwaukee, working in the Alberto Lab, where I conduct research in the field of molecular ecology, kelp forest – urchin barren dynamics, habitat loss, and marine conservation.

Research Interests

Macroalgal Ecology

Macroalgae are the foundation of many nearshore ecosystems. Specifically, macroalgal communities are sensitive to changing environmental conditions, which can drastically influence their health and population dynamics. I have been involved in projects that aim to document population trends, providing a baseline to understand the effects of climate change on biodiversity.

Biomechanics

The nearshore environment is a physically stressful place to live, with crashing waves and strong currents. Macroalgae found in these environments face a number of challenges while attached to the rocks, unable to move. I investigate how macroalgae survive under constant physical stress, by describing their material properties as well as their ability to ‘hold on’.

Population Genetics

Genetic diversity within a population can provide a range of functional responses when exposed to stressful conditions. I investigate how genetic diversity within kelp species maintains population resilience through connectivity and dispersal. My main goal is to provide non-invasive genetic monitoring tools to assess habitat health and help create a basis for practical approaches to habitat conservation.
