A research background in earthquake engineering seems at first sight like an unusual fit with studying tsunamis. But on her return from Sri Lanka in the wake of the 2004 tsunami, Professor Tiziana Rossetto discovered that very little research had been done into the effects of tsunamis on coastal infrastructure and she wanted to find out more.
