The web presence for the group of Peter L. Ralph at the University of Oregon. I am affiliated with the Institute of Ecology and Evolution, and am a member of the departments of Mathematics and Biology.

We work at the intersection of evolutionary biology, population genetics, probability, and statistics: developing theory about how populations evolve, adapt, and speciate; creating inference methods (and software) for genomic analysis; and doing data analysis on population genomics datasets. A focus is on geography: local adaptation, isolation by distance, and geographically explicit genomic datasets; but our work also ventures into phylogenetics and the evolution of gene regulatory networks.

Have a look at our people, publications, and teaching and events. Code, and some papers in progress, generally live on github.

Some collaborators: Gideon Bradburd, Yaniv Brandvain, Graham Coop, Brad Schaffer, Matt Dean, Steve Evans, Sebastian Schreiber.

Here is a statement put forward by G. Coop, M.B. Eisen, and M. Przeworski, and endorsed by a large number of scientists, with whom I agree:

In Defense of Science:

We are deeply concerned by the Trump administration's move to gag scientists working at various governmental agencies. The US government employs scientists working on medicine, public health, agriculture, energy, space, clean water and air, weather, the climate and many other important areas. Their job is to produce data to inform decisions by policymakers, businesses and individuals. We are all best served by allowing these scientists to discuss their findings openly and without the intrusion of politics. Any attack on their ability to do so is an attack on our ability to make informed decisions as individuals, as communities and as a nation.

If you are a government scientist who is blocked from discussing their work, we will share it on your behalf, publicly or with the appropriate recipients. You can email us at
