Her doctoral dissertation was titled The effect of cytotoxic drugs and radiation on mammalian cells and multicellular spheroid in vitro.
She developed an interest in the use of human genomics data to personalise radiotherapy to minimise radiation toxicity in cancer patients.
In November 2009, the Radio-Genomics Consortium was established under the American National Cancer Institute, in order to identify genetic determinants of radiotherapy toxicity.
[7] The aim of the consortium is to characterise the individual molecular profiles that reflect relevant biological phenotypes, to help predict tumour and normal tissue response to radiation.
In 2016, West was received the Weiss Medal from the UK Association for Radiation Research, for setting up the REQUITE international consortium.
