Tyler is primarily interested in the links between algal community structure and biogeochemical cycles, and how these relationships may apply to broader freshwater ecosystem structure and function. Currently, he is investigating temporal, spatial, and physical controls on microbial mats in the Dry Valleys of Antarctica.
