Harry Langford achieved a First Class BSc in Geography at the University of Sheffield in 2007, before completing a PhD in Environmental Science in 2012. His PhD research involved studying the microstructure, biogeochemistry and formation of cryoconite granules: biologically active aggregations of microorganisms, mineral particles and organic matter found on glacier surfaces. He utilised a range of spectroscopic and microscopic techniques during this research, from Fourier transform infrared (FTIR) spectroscopy to confocal laser scanning microscopy (CLSM). Since then, Harry has been researching in the field of soil biogeochemistry.

Research Interests

Geomicrobiology, glacier and soil biogeochemistry, bioflocculation, photosynthetic microorganisms, microscopic and spectroscopic techniques, soil security and environmental observation.

Current Research

Soil security and critical zone science
My current work involves designing a framework for critical zone science, the Earth’s outer layer from vegetation canopy to the soil and groundwater that sustains human life. This focuses on multidisciplinary earth observation with wireless sensor networks.

The structure and function of soil aggregates
This research involves studying the attachment and aggregation of microorganisms with organic and inorganic particulates, utilising both laboratory and field studies. In an extension of previous work, this project aims to incorporate aggregate life cycle and microbial function measurements, using a combination of spectroscopic, microscopic and ‘omics’ techniques.
