Predicting the future of gene flow in a changing ocean

Gene flow plays a critical role in maintaining genetic diversity, shaping adaptation, and supporting population resilience yet the processes governing genetic connectivity in marine systems remain poorly understood. I am working on mapping patterns of gene flow across marine species and investigating the drivers of connectivity by integrating ecological, oceanographic, and genomic data. Ultimately, this work aims to better predict how shifting ocean currents and changing temperatures will shape future patterns of gene flow and genetic diversity.

Developing tools for next generation landscape and seascape genomics

The field of landscape genomics aims to understand patterns of local adaptation and connectivity by integrating genomic and environmental data. I am working on developing tools that leverage genomic and spatial data to understand processes of evolution in natural systems. As part of this work I have developed a method for creating continuous maps of genomic diversity using moving windows available as the R package wingen and I have co-developed a comprehensive pipeline for individual-based landscape genomic analyses available as the R package algatr.

Mapping and conserving genetic diversity across California

As part of the Landscape Genomics Team for the California Conservation Genomics Project, I am leading analyses of genetic diversity using one of the largest multispecies whole-genome datasets assembled to date. I am mapping statewide patterns and hotspots of genetic diversity across hundreds of species and investigating the environmental, anthropogenic, and life-history factors that shape them across the tree of life.

Quantifying environmental drivers of genetic diversity

I am investigating how historical and contemporary environmental change shapes the geographic distribution of genetic diversity using whole-genome data from western fence lizards (Sceloporus occidentalis) across California. This work examines how climate change, wildfire disturbance, and local adaptation interact across space and time to shape genetic diversity and vulnerability to ongoing environmental change.
