Chris Carl A. V. Toyado

Chris Carl reconstructs past environments and climate using in/organic and isotopic geochemical techniques on sediment cores. He hopes that these reconstructions will help us understand the environmental conditions of the past and of today, for us to have a glimpse of what these environments will be in the future.
