Research themes

The research we conduct aims to develop our understanding of the biogeochemistry of modern-day and ancient environments and the way that it is affected by natural processes and the actions of mankind.

Our work interfaces with a wide range of different fields but the majority of work that we do can be divided to the seven following areas:

The work carried out in the OGU is highly interdisciplinary which means that we are constantly interacting with other researchers from across the globe as well as collaborators in other departments within the University through joint research initiatives such as  the Bristol Biogeochemistry Research Centre (BBRC).

Archaeological chemistry

This field explores the chemistry of a wide range of artifacts such as ancient pottery sherds, Egyptian funerary items and skeletal remains.

Chemical ecology

Previous work has provided new insights into the dietary choices of various invertebrate species and the functional roles that they play in the soil.

Environmental chemistry

Our interest in this field lies primarily in the detection and quantification of estrogenic and pesticide compounds in agricultural, sewage and river samples.

Forensic chemistry

We are interested in how soil organic geochemistry chemistry may be applied to criminal investigations in the detection of clandestine graves.

Geomicrobiology

Molecular signatures of micro-organisms, particularly in extreme environments, can give insights into evolution and the search for extraterrestrial life.

Organic matter cycling

Understanding how organic matter changes in the environment is key to understanding carbon storage and, ultimately, climate change.

Palaeoclimatology

Molecules found in sediments can provide temperature records, spanning millions of years, helping us explain past climate and predict future events.
