Overview

Postdoc working on the NERC funded project "Legacy Wastes in the Coastal Zone: Environmental Risks and Management Futures".

I am an environmental scientist interested in water and soil contamination. My research involved the study of contaminated-bearing matrixes from bulk to nano-scale in mineralised catchment and waste-impacted coastal areas. I like to apply a multidisciplinary approach to investigate environmental challenges.

I am always happy to discuss research ideas, create new connections and expand my scientific and human knowledge.
