Research Interests

  • Gas biogeochemistry
    Development of analytical methods for determination of trace gases in marine environments
    Experimental approach to explore the biogeochemical processes involved in the production and consumption of these trace gases
    Publications: Lin et al., 2010, Biogeosciences; Lin et al., 2012, GCA
  • Stable isotope labeling and compound-specific isotopic analysis
    Development of analytical techniques required for compound-specific isotopic analysis, including HPLC, GC, and several wet chemical methods
    Application of stable isotope labeling to study marine benthic ecosystems
    Publications: Lin et al., 2010, RCM; Lin et al., in prep
  • Characterization of dissolved organic matter (DOM) using ultra-high resolution mass spectrometry
    Application of Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS) to resolve the complex mixture of DOM in pore waters retrieved from marine sediment
    Experimental approach to investigate the underlying mechanisms (biological vs. abiotic) responsible for compositional changes of DOM

Postdoc project

My postdoc project is part of the MARUM Project GB3 entitled ‘Transformation of matter and the role of microbes in subsurface sediments’. The scientific questions to be addressed can be divided into two parts:

  • What is the molecular composition of sedimenatry dissolved organic matter (DOM)? How does it change over the course of diagenesis?
  • What is the underlying mechanisms (abiotic vs. biological) that cause changes in DOM composition?

To address these questions I applied the following approaches:

  • Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS); in collaboration with Prof. Dr. Boris Koch at the Alfred-Wegener Institute and Dr. Matthias Witt at the Bruker Daltonics
  • Computer programming (Matlab) and multivariate statistics
  • Laboratory experiments simulating diagenetic processes

Materials for this project were taken from the Guaymas Basin during the research cruise RV Atlantis AT15-56 (2009). The chief scientist of this cruise is the UNC microbiologist Prof. Dr. Andreas Teske.
Within the context of MARUM Project GB3 I also co-supervise PhD student Guangchao Zhuang for his PhD project entitled "The generation and fate of low-molecular-weight methylated substrates for methanogenesis in marine sediments".
