In the geochemistry and geobiology theme, the focus is twofold. The first is to maintain
a leading role amongst scientific laboratories using the clumped isotope method. The stable
isotope laboratory (SIL) is one of only two laboratories that can measure the Δ48 proxy and
apply it to various aspects of carbonate geochemistry. The second focus is understanding
microbial carriers and biosignatures in microbialites. Both are important for identifying
microbial origin of ancient carbonates.
