Impact of natural hazards/pandemics

1. Earthquakes in the South and North Islands have led to a group of us winning a Marsden in 2013, led by S. Ellis

2. Pandemic. The impossibility of going to Taiwan during the pandemic has led me to:

   (a) propose and produce several educational videos and

   (b) write a detailed manual on how to sample and analyse fluids. These videos and manual were followed by livestream sampling where I watched and instructed remotely, from Lower Hutt, as scientists collected fluid samples in Taiwan.
