Jeanne Romero-Severson Professor

Quantitative and population genetics in natural populations
 Jeanne Romero-Severson

Research Interests:

In 100 years we have peered at the natural world and managed to build a model of what we see, from simple Mendelian phenotypes to genetic control systems of exquisite precision to the improbably noisy biochemical reactions that produce this precision. In my program we use this accumulated knowledge to study the genetics of natural populations, from the native forest trees of eastern North America to insect vectors of human disease and most recently, beneficial seed endophytes.

Our basic research program focuses on:

  • Population dynamics, spatial genetic structure, gene flow, adaptive genetic variation and spontaneous interspecific hybridization, primarily in Quercus, but also in Castanea, Juglans and Fraxinus.
  • Genetic architecture and speciation mechanisms in the genus Quercus
  • Gene discovery and population processes in culicine and anopheline mosquitos

The tree genetic Core Facility does marker development and genotyping for both natural populations of forest trees and cultivated nut trees. We focus on scalable genotyping approaches that suit both small growers and large projects, and can be used to answer both applied and basic questions.
