My research sits at the interface between biology, geology, population ecology and climate science. I have worked mostly on oligotrophic environments addressing fundamental questions related to ecosystem-substrate interaction and evolution from the scale of a catchment down to that of minerals. I am currently involved in an interdisciplinary effort focused on the initial stages of rock colonization by biotic communities (microbes, plant and mycorrhizae) and the initiation of mineral transformation and soil genesis. I also co-lead a world-wide adventure science initiative that pairs researchers with trained explorers under the common aim of understanding the critical role of microbes in initiating element cycle and soil genesis in the extreme environments of high altitudes and polar regions.
