Mike has been included in the last 3 RAE/REF returns as part of a consistently achieved Grade 5 submission (Open University). In the REF2014 he was graded as GPA 3.5, including papers from Geology, Chemical Geology, Lithos, and Science.

Mike has received international recognition through >120 publications which have been cited >4000 times, resulting in an H index of 34 and an i10 index of 46 (Sources: Google Scholar; ResearchGate - RG score c. 39). Outputs eligible for the current REF cycle include papers in Chemical Geology, Palaeogeography, Palaeoclimatology, Palaeoecology, GCA, Geological Society of America (GSA).

Externally, Mike is currently an Officer of the Mineralogical Society; Vice Chair of Large Igneous Province Commission at IAVCEI. He was Chair of Volcanic and Magmatics Study Group, UK (2015 – 2018), executive member of VMSG committee for 20 years, and previously served on Geological Society of London and Mineralogical Society SIGs Science Committees, and the Schlumberger, Collins and Hay Medals awards Committee.

Mike was nominee (2015) for the prestigious VMSG Award. In recent years he has given numerous radio, TV, and newspaper interviews, appeared on BBC, History and Discovery TV Channels, and delivered commentaries regarding flood basalt volcanism, the KT boundary, and the dinosaur extinction.

OVERVIEW OF RESEARCH INTERESTS

Mike has an established and very broad research and analytical experience through collaboration with scientists within the UK and internationally. Many of his publications are multi-author works in high-profile journals. He has a reputation for reliable and thorough fieldwork and detailed field-sampling, and high-quality analytical data performed on collected materials which can be robustly placed within their geological context.

His research interests range from volcanology and geochemistry to sedimentology, weathering studies and river chemistry. He has investigated materials from throughout geological history (Proterozoic to Cenozoic). His key research themes may be summarized as the following themes:

The chemical and environmental memory of Large Igneous Provinces: evaluating linkages with climate change

Deep weathering processes: environmental chemical and isotopic fluxes

Research interests

SUMMARY

Mike's focus is (i) flood basalt volcanism and its environmental effects; (ii) tropical weathering and lateritization processes. He uses a variety of analytical techniques - geochemistry (XRF, ICP and isotope studies), geochronology (Ar/Ar and Palaeomag). Fieldwork investigations are worldwide: in detail the evolution of the Deccan Traps large igneous province (LIP), and LIPs elsewhere (i.e., CRBP, BTIP, Iceland, Hawaii, Emeishan, Kalkarindji, Shatsky Rise). He is collaborating with Chinese scientists on projects documenting the development of the Himalaya and the associated floral evolution. His weathering studies have documented the fate of elements and behaviour of isotope systems during extreme alteration.

Postgraduate supervision

Mike is an established research supervisor (10 PhD students and c. 10 MSc, MRes students since 2000). These projects have resulted in >50 joint authored peer-reviewed publications. Enquiries and applications are welcomed in the following research areas:

1) All areas of volcanology, in particular those related to the study of large igneous provinces, and associate environmental and/or biotic change.

2) Geochemical and isotopic studies of deep weathering, in particular linkages between their development to environmental change

Themes for past, present and future PhD studies include:

Volcanology:

Flood basalt volcanism

Environmental effects of volcanic eruptions

Interrogating the sedimentary record for LIP events

Chemical memory of LIP eruptions

Ancient Icelandic eruptions

Deep weathering processes:

Laterites and lateritization processes

Behaviour of isotopic systems during deep weathering

Evaluating weathering profiles as a paleoenvironmental proxy environment
