Dr Mark Roberts

BSc (Hons), MSc, PhD, FGS

Bio-geochemist

Mark is an environmental bio-geochemist with an undergraduate degree in exploration and resource geology undertaken at Cardiff University. Mark's Ph.D. focused on the stimulation and exploitation of indigenous iron-reducing microbial communities within oxidized mine wastes to facilitate metal recovery. Mark also undertook an M.Sc. in Applied Environmental Geology (also at Cardiff) and is a skilled laboratory research scientist who loves nothing more than sampling columns, running laboratory analysis and working with large cumbersome ICP datasets! Mark is a fellow of the geological society of London.

Rhys Savage

BSc (Hons), MSc, FGS, FRGS

Environmental Geo-scientist / PhD Researcher 

Rhys is a graduate geographer come geochemist who undertook an MSc industrial placement at Geochemic Ltd between June and October 2018. As part of his industrial research project Rhys designed and implemented novel carbonation kinetic experiments on ultra-mafic mine waste and carried out detailed mineralogical and elemental characterisation analysis. Following the completion of his MSc project, in which he received a distinction, Rhys started a PhD at Cardiff University School of Engineering looking into geochemical method development for mine waste characterisation. The PhD is a KESS2 studentship for which Geochemic is part funding as the industrial partner. Rhys has extensively used ED-XRF for the analysis of rock materials soils and sediments during both his undergraduate projects (looking into contaminated sediments in Swansea) and during his MSc project with us. He has also gained experience in laboratory characterisation of mining wastes having been a great help with running many EN15875 NP tests, ABCC and oxygen consumption tests.

Rhys is generally in Geochemic 3 days a week for the duration of his PhD during which he can be contacted on the office number +44 (0)1495 617474 or via email rsavage@geochemic.co.uk
