Ian is a micropalaeontologist who studies calcareous benthic microfossils, particularly ostracods (microscopic Crustacea), but also foraminifera, to reconstruct past environments. His work spans much of the last 200 million years of earth history, with projects as diverse as the late-glacial history of lakes in Scotland and the vast inland seas of the Ponto-Caspian region, to sea-level change studies in the salt-marshes of the UK. 

Much of his work has focussed on the history of the early Jurassic seas of NW Europe, but his work has also led him to investigate the deep ocean sediment cores from the Indo Pacific. The same skills are also put to good use helping unravel the environments associated with geoarchaeological projects in the UK, Qatar and Kenya.

He is the Course Director for the MSc in Applied & Petroleum Micropalaeontology and manager of the School's stable-isotope facility, SILLA.


  • 1989 - PhD in Early Jurassic ostracods form North-west Europe - University College London
  • 1985 - MSc in Micropalaeontology - University College London

I am currently the Module leader for ESC M213 Environmental and Evolutionary Palaeobiology . I also teach on the 3rd/4th year Micropalaeontology undergraduate module. I lead a second year field trip to the Wessex Basin (Dorset Coast) and co-teach sedimentary environments during the 3rd year fieldtrip to Spain.

I teach ESC M500 Ostracoda and co-ordinate ESC M507, the Micropalaeontology Project on the MSc in Applied & Petroleum Micropalaeontology and am administrative leader on a further 2 modules.

Postgraduate supervision

Much of Ian Boomer's research focuses on a group of calcareous microfossils, the Ostracoda (or ostracods). An ostracod can be thought of as a microscopic shrimp-like organism (usually less than 1mm long) living inside a bi-valved carbonate shell or carapace. These little bugs have been around for the last 500 million years and live today in just about every aquatic environment. Their fossils can be used to date rocks, record major changes in the world’s oceans, trace climatic changes such as sea-level rise amongst other uses and even track pollution. Dr Boomer has a particular interest in the geological record of ostracods around the period of the latest Triassic and Early Jurassic. Further research focuses on using these fascinating bugs to find out more about the rapid, global climatic changes that occurred between about 15,000 and 10,000 years ago.

Dr Boomer welcomes enquiries from prospective doctoral researchers in his areas of interest.
