Haijun Peng
I am a post-doctor at the Department of Forest Ecology and Management working on a Kempe Foundation-funded project "Does Long-term Drainage reduce Mercury Deposition in Boreal Peatland? Using Novel Hg(0) Eddy Covariance to Decipher Hg Flux over Drained and Natural Peatlands". My research interests are (1) Mercury cycling in both boreal peatland and low latitude alpine peatland/wetland ecosystems, (2) Early anthropogenic activities and natural climate variability impact on the centennial-millennial timescale Mercury deposition in wetlands, (3) Wetland Methane emission monitoring using the Eddy Covariance technique, and (4) Holocene hydroclimate reconstruction using cellulose isotopes in peat deposits from boreal and monsoon east Asia.
