Location: Environment Centre Wales (2nd Floor)

Responsibilities within SENRGy/BU

I am a postdoctoral research officer on a NERC funded research project, titled ‘Uplands-N2O’ in collaboration with Bangor University, Rothamsted Research, Swansea University, Texas A&M University-Kingsville and Leicester University. My role within the project is to quantify emissions of nitrous oxide, a powerful greenhouse gas, from excreta deposited by sheep grazing in upland regions.

I sit on the CNS Women’s Network Steering committee and am the post-doctoral representative for the ECW 2nd Floor laboratory user group.
