As her interest in global health grew, Clark became keen to work in a developing country. Clark served as Executive Editor of the International Centre for Diarrhoeal Disease Research, Bangladesh (ICDDR,B) and its Journal of Health, Population and Nutrition and she also trained doctors in scientific writing and publication. Whilst in Dhaka Clark wrote for The BMJ, The Guardian and Grand Challenges Canada. She completed an academic writing residency at Lake Como. Here she investigated the over-medicalisation of global health at the Rockefeller Foundation Bellagio Center, and wrote a four part series outlining whether global health had become too medicalised, the medicalisation of mental health, the medicalisation of non-communicable diseases and the medicalisation of Universal Health Coverage campaigns.
