Dr Diane Purchase

Diane has a keen interest in the field of environmental remediation. She has published widely and supervised a number of PhD students on:

• the role of microorganisms in pollution control (e.g. removal of heavy metals using microalgae; microbial enzymatic degradation of prion protein; application of biosurfactants to remediation environmental pollutants)
• the removal of heavy metals in constructed wetlands
• microbial contamination in the domestic environment
