In his PhD research with Dawn Sumner, Tyler explores how modern microbial communities interact with their surrounding environment to form larger structures like microbial mats and microbialites. Much of his work focuses on microbial mats growing at the bottom of ice-covered lakes in Antarctica. In these isolated environments, microbial communities form thick mats with complicated geometries such as peaks and webs. Tylerís ultimate aim is to develop growth models for these structures that will help better interpret the behavior and evolution of ancient microbial communities that leave similar deposits preserved in the rock record. Tyler has participated in the Pavilion Lake Research Project since 2010. This research program complements his work with polar microbial communities, and he is particularly interested in the factors that influence preservation of chemical and morphological biosignatures in the Lake Pavilion microbialites.

PLRP Research Objectives

Document spatial variability of microbialite community growth rates, providing context for their association with particular microbialite morphologies and chemical biosignatures.
