In 2021 Peter Buzzacott, PhD, of Curtin University in Perth, Australia, received DAN’s Alfred Bove Research Grant for Cardiac Health in Scuba Diving. What began with a simple proposal has since developed into a training network for the next generation of scientists and led to a research network between Curtin University and Fiona Stanley Hospital in Western Australia.
You check in at the dive shop, sign your waivers, get your gear on the boat, and set up your BCD on your first tank for the day.
