Biography:

Tamsin O'Connell started academic life as a chemist at the University of Oxford. The lure of applied science led her to archaeology, working with Prof Robert Hedges at the Research Laboratory for Archaeology and the History of Art in Oxford, firstly for her undergraduate dissertation followed by a SERC/NERC-funded DPhil. She had a Wellcome Trust Post-doctoral Fellowship, then two post-doctoral positions at the RLAHA. She joined the Department in Cambridge in 2004, with a Wellcome Trust University Award, to set up an isotope and palaeodiet laboratory, now called the Dorothy Garrod Laboratory.

Research Interests

My research traces signals of diet and climate in human and animal tissues, using isotopic analysis. As well as application to archaeological, ecological and epidemiological case studies, my work focuses on developing our understanding of the underlying principles, so as to improve the resolution of interpretations and conclusions that we can draw from isotopic analyses.

Topics
  • Stable isotope analysis 
  • Palaeodiet
  • Palaeoclimate
  • Ecological studies of foodwebs
  • Nutrition and epidemiology
  • Biomolecular analysis of human and animal remains

I am presently involved in the following research projects:

Analytical Equipment used

Continuous flow isotope ratio mass spectrometry: Thermo Finnigan Delta V and MAT253 mass specs with various peripherals including EA, TCEA, gas bench and Kiel device.

We carry out our analyses in the Godwin Laboratory in Earth Sciences.

Research Supervision

I supervise students on a range of topics covering archaeological and ecological applications of isotopic analyses. As well as the research students listed below, I supervise Masters and undergraduate projects on a range of bioarchaeological topics.
