Biological Soil Crusts

FOcus Areas


  1. Biological Soil Crusts: microbial communities that aid in nutrient cycling in arid and semi-arid lands.

  2. Soda Lake: microbiology of a dry alkaline soda bed.



Research topics


  1. Phylogenetic composition of cultivable airborne microorganisms.

  2. Quantification of viable bacterial abundance and composition in biological soil crusts.

  3. Development of field and benchtop assays for catalase activity.

  4. Quantification of viable bacterial abundance and composition in Soda Lake cores.

  5. Chemical analysis of soda lake.

  6. others TBD...
