RESEARCH

I am a multi-disciplinary scientist working on the diversity and phylogeography of foraminifera to improve the resolution and understanding of palaeoceanographic proxies and the microfossil record. Researchers use foraminiferal fossil shells to reconstruct ocean circulation and climate in the past, by assuming that all the shells of a specific morphospecies were constructed within the same environmental range. Evidence from small subunit ribosomal RNA genotyping in living planktonic foraminifers indicate that morphospecies often represent several distinct genotypes which are adapted to different environments.

Genotypes of morphospecies therefore build their shells in different environments from one another and scientists are unknowingly processing a mixed assemblage. This has consequences for researchers using marine sediment assemblage data and shell geochemical signatures to determine past oceanographic and climate history. Once the genetic structure is understood, proxy inconsistencies can be resolved. Additionally, there may be a vast storehouse of information for past climate reconstruction to be exploited.
