David J Paez, Ph.D.

I am a quantitative biologist with special interests in the evolutionary ecology of host-pathogen interactions in aquatic systems. I use experimental and survey data to test alternative models describing the mechanisms of host-pathogen interactions at different levels, such as within and among hosts.

My research career started in fish biology, investigating ecological and evolutionary factors that lead to alternative reproductive phenotypes in Atlantic salmon. I then moved into the field of disease ecology where I further developed skills in quantitative biology, evolutionary ecology, and genomics. During my postdoc years, I conducted disease ecology research in several systems, including spongy moth-baculoviruses and fruit bats-paramyxoviruses. Since about 2018, I have been studying disease ecology in fish species of the Pacific Northwest, including salmonids and clupeids.
