Research Interests

Colonization, local adaptation and life history evolution

Over the past decade, I have developed a multidisciplinary research program on salmonids. During my graduate school experience, which I completed in 2010, I combined population genetics and morphological methods with modern genomic transcriptome profiling to understand the life history, evolution, and ecology of Sockeye Salmon.

 

View from "The Gates" of Aniakchak River. There was a breech in the caldera wall that resulted in a flood connecting the inside of the caldera with the Pacific Ocean. Sockeye Salmon subsequently colonized the caldera and locally adapted to outlet and beach habitats. I measured adaptive differences in adult body depth and egg size. The current populations colonized only 500 years (100 generations) ago (after a large eruption; determined by genetic coalescence).

 

There are also differences in the body shape and gene expression of juveniles of the caldera compared to Albert Johnson Creek, a downstream tributary at the base of the volcano.

 

 

 

 

 

 

Genomics of nonmodel organisms

Currently, as the senior postdoc in the Bernatchez Lab, One of the research programs that I am leading uses genomic tools to understand the ecology and best management practices of American Eel. I take a multifaceted approach to further understand their ecology and evolution, including high resolution linkage maps, genome scans, transcriptome profiling and full genome sequencing.

 

American Eel young juveniles (glass eels) migrate from saltwater to freshwater at high tide under the cover of darkness. Here we capture these young glass eels for behavioral and controlled rearing experiments

 

 

 

 

 

 

 

 

Large, much older yellow eels are released back into the St. Lawrance after non-lethal genetic sampling.
