I am a postdoctoral Research Associate in environmental epidemiology within the Department of Epidemiology and Biostatistics, where I also completed my PhD.  My PhD focussed on exposure to water disinfection by-products during pregnancy in the Born in Bradford birth cohort.  My academic background covers both biological and social disciplines, with a BA in Human Sciences (St John’s College, Oxford) and an MSc in Epidemiology (Imperial College London).

Since completing my PhD I have worked on both the COSMOS and SCAMP cohort studies which are investigating potential effects of exposure to radio-frequency electromagnetic fields (from mobile phones and other wireless devices) on adult health and children’s cognition respectively.

At present I am working on the Traffic Pollution and Health in London project, examining the relationship between traffic-related noise and air pollution and risk of adverse reproductive outcomes (e.g. low birth weight and pre-term delivery).

My research interests and experience cover a range of environmental exposures which we commonly encounter in our daily lives:  water disinfection by-products, electromagnetic fields (including from mobile phones and wireless devices), air pollution, and noise.  I also have a particular interest in reproductive health.


Key research areas:

  • Water disinfection by-products
  • Electromagnetic fields, radio-frequency, mobile phones and wireless devices
  • Air pollution
  • Noise
  • Reproductive health
