Research Interests and Publication of My Graduate and Undergraduate Work

PhD thesis project

As a PhD student, my research interests could be divided into two categories:

  • Gas biogeochemistry

Analysis of trace gases other than methane in marine sediment and investigation of biogeochemical processes involving these gases with experimental approaches. The trace gases that I have studied included methylated sulfides (e.g., methanethiol, dimethyl sulfide; Lin et al., 2010, Biogeosciences) and molecular hydrogen (Lin et al., 2012, Geochimica et Cosmochimica Acta). In addition, I co-supervised other PhD student for their studies of trace gas biogeochemistry (Xie et al., 2013; Zhuang et al., in prep.).

  • Isotopic analysis of lipids, stable isotope probing, and the "deep biosphere"

I used intact polar lipids derived from cell membrane as a proxy for living prokaryotes (Bacteria or Archaea). Combining the stable isotope probing technique with lipid analsysis, I investigated the carbon source of so-far uncultivated archaea in the marine deep biosphere (Lin et al., 2010, Geomicrobiology JournalLin et al., 2010, Rapid Communications in Mass Spectrometry; Lin et al., 2012, Environmental Microbiology). I also co-supervised other students for their work on lipids or other biomarkers (Braun S., 2011, MSc thesis; Zhu R., ongoing project).

Master and bachelor thesis projects

I have explored the following topics as an undergraduate or master student:

  • Paleoceanography

I reconstructed the Holocene paleoceanographic record of the upper reach of Kuroshio (from the western Philippine Sea to the southern Okinawa Trough) using multiple approaches, including assemblages of planktonic foraminifera, stable oxygen isotope, and Mg/Ca of foraminiferal tests (Lin et al., 2006, Marine Micropaleontology).

  • Soil science

A study that investigated the effects of topography on soil morphology (Lin et al., 2005, 2007, Geomorphology).
