Maria Orive

Associate Professor, Ecology and Evolutionary Biology
Haworth Hall

Dr. Maria Orive's research area is theoretical population genetics.

Area of Interest and Research

  • Theoretical population genetics
  • Life history evolution
  • Relationship of population structure and life-history attributes to gene flow
  • Hybridization and genetic diversity
  • Within-host viral population dynamics

My research area is theoretical population genetics; I use mathematical models to investigate the roles that such complexities as clonal and asexual reproduction, non-random mating, and different patterns and types of dispersal play in determining genetic structure; I also apply evolutionary theory to questions of how these different life histories evolved. Specific areas of present and future research include models investigating the role that life history plays in determining effective population size and levels of local differentiation, the use of multi-locus genotype information in analyzing hybrid zones, tradeoffs between clonal and sexual life phases, the evolution of senescence, and the dynamics of viral populations within their hosts.
