Overview

I am a soil biogeochemist with 10 years’ research experience, mainly specialising in soil and peatland biogeochemistry, methane and carbon dioxide dynamics in peat soils, and roadside nitrogen dynamics on acid grasslands. My recent focus has been upon carbon uptake by and emission from soils (e.g., soil-plant interface); and how management can affect the carbon budget and the surrounding water bodies (e.g., DOC / POC export). Now currently working on SPECTRA: Soil processes and ecological services in the karst critical zone of SW China.

Broad research specialisms:

  • Soil and peatland biogeochemistry;
  • Methane and carbon dioxide dynamics in peat soils;
  • Roadside nitrogen dynamics on acid grasslands;
  • Carbon uptake by and emission from soils (e.g., soil-plant interface); and how management can affect the carbon budget and the surrounding water bodies (e.g., DOC / POC export);
  • Karst environments and soil erosion.

Qualifications

2004 – 2007 PhD in Environmental Science. Thesis entitled: Road salting effects on upland soils, soil solutions and freshwaters, Environment Department, University of York, UK.

2000 – 2003 BSc. (Hons) Environment, Economics and Ecology. First Class with distinction, Environment Department, University of York, UK.

Research projects

NE/N007603/1 SPECTRA: Soil Processes and Ecological Services in the Karst Critical Zone of Southwest China. PI: Prof. Tim Quine (University of Exeter); Co-Is: Tim Barrows (University of Exeter), Ian Hartley (University of Exeter), Jeroen Meersmans (University of Exeter), Jennifer Dungait (Rohamsted) and Heather Buss (University of Bristol).

Covering extensive parts of southwest China, Karst is a key landscape that is exceptional because rapid and intensive land use change has caused severe system degradation within only the last 50 years. The rapid increase in environmental degradation due to rocky desertification in the Karst is comparable to that caused by the better known extreme rates of erosion of the sandy loess soils in N China. Therefore, establishment of a CZ in the karst landscape of SW China along a dynamic perturbation gradient in varying states of transition between states of rocky desertification to natural forest would fill a significant gap in the current database and research effort. Furthermore, there is a socioeconomic imperative to establish a CZ in the karst landscapes of SW China. The population of 36 million are amongst the poorest in China, with regional GDP less than 50% of the national average, and sustainable solutions to land management, potentially including abandonment and economic compensation, will be integral to lifting the population out of poverty.

We are investigating the integrated geophysical-geochemical-ecological and social responses of the CZ to past perturbations, the CZ spans a gradient from undisturbed natural vegetation through human perturbed landscapes at 3 levels of use – sloping farmland, recovery phase 1 (recently abandoned, within 5 years) and recovery phase 2 (secondary forest, abandoned > 5 years). We are integrating measurements of: (1) plant, soil, mycorrhizal fungi and free-living soil microbes; (2) rates of rock weathering, elemental release and soil formation processes; (3) rates of erosion and soil redistribution; and, (4) pools and fluxes of soil organic C (SOC), nitrogen (N) and phosphorus (P). Through explicit consideration of plant-microbe-soil and plant-microbe-rock interactions, we will identify the biological controls on nutrient availability, soil formation and loss in the CZ.
