Civil Engineering Building (H20)
Level 3, Room CE309
Senior Lecturer, School of Civil and Environmental Engineering
Level 1: I investigate how rainfall might change in the future
Level 2: I use statistical hydrology to analyse historical rainfall and future climate projections
Level 3: I develop methods to evaluate and correct simulations from General Circulation Models
Interest in engineering
Why did you get into engineering?
I studied engineering so that I could solve practical problems and make positive changes to the world around me
What are your research goals?
My research goals are to better understand what will happen to rainfall into the future and how these changes will impact society, particularly with respect to flooding and droughts.
What do people not understand about what you do?
We have relatively short historical records of rainfall and streamflow that make it difficult to separate the impact of natural cycles of variability, such as El Nino, from the impacts of anthropogenic climate change.
Advice for prospective civil engineers
Civil engineering is a great career that can allow you to travel the world, improving the infrastructure that people use every day. Pay attention to the infrastructure that is around you and maintain your curiosity about the way that the world works. Engineers are creative problem solvers.
