Biography:

Dr Sami Ullah is based at the University of Birmingham, UK and his research is mainly focused on the biogeochemistry of nitrogen and its linkages to carbon and phosphorus cycling under global change in soils under forest, peatland/wetland, grassland, and agricultural crops. The impetus of his research is to advance mechanistic understanding of the response of key microbial functions such as denitrification, nitrogen and carbon mineralization, biological nitrogen fixation, greenhouse gas fluxes and soil enzyme activity to land-use and climate change at catchment scale.
His research is underpinned by the development and application of novel analytical field techniques including stable isotopes and high-resolution sensor technologies to explore novel relationships between nutrient cycling, plant-microbe interaction and environmental conditions. This knowledge supports the development of new conceptual frameworks and feeds into dynamic ecosystems models for a more realistic assessment of the threshold of biogeochemical functional breakdowns under perturbations; and identification of techniques for sustainable utilization of natural resources, ecosystem restoration, food security and protection of environmental quality.

Research Areas:

  • Denitrification
  • N mineralization and biological N fixation in terrestrial and wetland ecosystems

Current N-related Projects:

  • Response of N cycling in forest soils exposed to elevated atmospheric CO2. Denitrification in soils under natural and agricultural ecosystems. Biological N fixation in peatlands under chronic reactive N deposition in UK and Sweden.
