Latest news

bendle-james-group-rain-shadowIn January 2019 Dr Bendle participated on an NSF funded field campaign(PIs: Dr Kathleen Johnson - UC Irvine; Dr Mick Griffiths – William Patterson University) to survey and sample cave and karst systems in Vietnam and Laos. These pictures illustrate the dramatic ‘rain shadow’ effect of the Annamite range and contrast in climate from wet season Vietnam to dry season Laos.




bendle-james-soil-lakeIn summer 2018 we undertook the first systematic surveys of 3-OH-FA biomarkers  - and the taxonomy of their gram-negative bacterial producers - in soils and lake sediment across the USA. The team did 7500 miles of driving, sampled 35 lakes and collected hundreds of soil samples. 

The samples collected in the USA in summer 2018 are the basis of a new collaboration between UoB (Dr, James Bendle, Dr Afrifa ‘Kweku’ Yamoah, PhD student Alice Hardman and Huub Zwart (now working in industry), leading the geochemical work and Dr Dan Read (CEH), and Dr Jessica Conroy (UIUC), leading in bacterial soil ecology, rRNA and eDNA. A GEES Pump-priming and UoB-UIUC Bridge award helped to fund pilot data and field work and provide stimulus for a successful Leverhulme Trust award. The campaign also relates to a broader collaboration with researchers at the China University of Geosciences (CUG) in Wuhan, especially Dr Canfa Wang (who visited Birmingham for two years, during his PhD, as a CSC scholar).

Recent Grants

£283,946, Leverhulme Trust Grant funded (start summer 2018): “Unlocking the Toolbox of Soil Bacterial Biomarkers” PRG-2018-110.

NERC Standard Grant funded (start summer 2017): Dunkley Jones, T, Bendle J. et al., 2016, £628,079, ‘Reducing Greenhouse Climate Proxy Uncertainty’,


James has generated >£2 million in external research income from UK and international funding councils, agencies and charities, published numerous articles, designed and taught new post-graduate and undergraduate field and classroom based courses. He has participated on five oceanographic research cruises and 9 palaeoclimatological field campaigns in Vietnam, Laos, the USA, Scotland, Japan and China (leading four).

From 2013 to 2019 a significant portion of James’ time was dedicated to his role as the Director of the NERC CENTA Doctoral Training Partnership (DTP). Funded by a £5,060,000 block grant from NERC, CENTA stands for Central England NERC Training Alliance (www.centa.org.uk).

Postgraduate supervision

James is part of a team of paleoclimate focused academics at Birmingham who jointly supervise a thriving community of palaeoclimatology focused PhD students including: including: Alice Hardman (NERC CENTA DTP),  Bridgette Warren (Leverhulme Forest Edge), Yang Yi (CSC Visitor Wuhan, CUG, China), Jinjing Liu (CSC visitor Tongji, China), Jonathan Hall (NERC Oil and Gas CDT) Kate Newton (NERC – UK), Marcelo Mota (Brazil).

I am committed to training and developing talented Masters level students and undergraduates as researchers. This is achieved through laboratory based projects and externally funded bursaries (16 bursaries so far: from The Geological Society, Nuffield Foundation, NERC-IODP, external partners) to participate on fieldwork and undertake laboratory assistantships.


Priority research themes

  • Biomarker proxy development.
  • Greenhouse worlds, future analogues, Cenozoic and Holocene climate evolution.

We use molecular biomarkers (in red) to study modern and past environmental processes and conditions:


bendle-james-organic-geochemistryOrganic carbon compounds are ubiquitous, abundant and sometimes overlooked components of oceans, lakes, sedimentary rocks and even atmospheric aerosols. Directly, or indirectly, they fuel all biogeochemical processes. As a paleoclimatologist, trained in molecular biogeochemistry, James is interested in the source, structure, and distribution of such naturally occurring compounds (biomarkers). His research is focused on the development of biomarker proxies of environmental parameters (e.g. terrestrial and sea-surface temperatures, relative humidity, C3/C4 plant distribution, wetland extent) and their application to answer questions about past climatic and environmental changes. Below is a table giving some examples of high utility biomarker applications, as applied to palaeoclimatology:
