Kay is a key member of the team organising medical research expeditions at the University College London (UCL) Centre for Altitude Space and Extreme Environment (CASE) Medicine.

These have included the Caudwell Xtreme Everest expedition (2007) and Xtreme Everest 2, which took place in March 2013. These expeditions involve using healthy volunteers to improve our understanding of the effects of hypoxia, and thus development treatments to improve outcomes. A key feature is the use of CPET to examine oxygen efficiency and utilisation, and Kay helped deliver CPET testing on a number of the expeditions.
