Dr. Cornejo’s research is in the area of population genetics, genomics and the evolutionary biology of infectious diseases. He is interested in understanding the evolutionary history of organisms, particularly, microorganisms and how selection, mutation and recombination shape genomic variation.
Dr. Cornejo’s primary research is in:
- Understanding from retrospective genomic analysis the demographic history of (micro)organisms and identifying candidate genes that might have been involved in their adaptation to their current niche (either host or environment).
- Ecological and evolutionary scenarios that can explain the maintenance of toxic agents that kill organisms that produce them.
- The genetic basis of phenotypic variation in complex traits like disease susceptibility in organisms with very distinct genomic architectures like Theobroma cacao or humans.
Dr. Cornejo is an assistant professor in the School of Biological Sciences at WSU and affiliate faculty with the Paul G. Allen School for Global Animal Health.
