Carol is interested in exploring how the ecology of South American plant species, along with their leaf waxes and the diverse ecosystems they inhabit, can be utilized as effective biomarkers. Understanding these relationships provides valuable insights into ecosystems and climate change indicators.<\/p>\n\n\n\n<\/div>\n \n <\/div>\n\n\n \n \n \n

Chan-Mao is a PhD candidate in Josh West\u2019s research group and when not spending months in the field collecting samples and data, or in the West lab, he is doing organic geochemistry lab rotations to study biomarkers – both plant wax and GDGTs – in soil elevation transects, river sediments in Nepal. The goal is to use biomarkers to track the provenance of landslide deposits.<\/p>\n\n\n\n<\/div>\n \n <\/div>\n\n\n \n \n \n
