We investigate lipids, biomarkers and stable isotopic signatures (C, H, S and N), paleogenomics of organic matter preserved in recent environments to understand changes impacted by humans, natural biogeochemical cycles and various environmental proxies (temp, pH, redox conditions, microbial community structure). Such environments include freshwater-hypersaline lakes, estuaries, deltas, oceans and caves. We also investigate the fate and source of petroleum in the environment.
