Biography
Steve received his PhD in Applied Mathematics from the University of Washington (Seattle). He then went on to a post-doc at the Advanced Studies Program (ASP) at the National Center of Atmospheric Research (NCAR). It was during this post-doc that he first visited Australia, participating in the Southern Ocean Cloud Experiment. Steven went on for second post-doc at the University of Manchester (then UMIST) under a US National Science Foundation international award.
Steve is a Chief Investigator in the ARC Securing Antarctica's Environmental Future (SAEF) research centre, leading a program on precipitation processes.
He currently serves as the co-chair of the Expert Team for Weather Modification for the World Weather Research Program (WWRP). He also serves as the Editor for the Journal of Southern Hemisphere Earths System Science.
Research interests
Clouds and Precipitation over the Southern Ocean and Australia
Steve leads a research team studying clouds & precipitation (cloud microphysics) and boundary layer meteorology. His specific interests include the Southern Ocean, orographic precipitation over SE Australia and Tasmania, and the trade wind cumulus clouds off of Queensland.
Supervision interests
I have supervised PhD students conducting research on cloud microphysics and boundary layer meteorology. When possible, I like to have students involved in fieldwork with recent field projects located in the Snowy Mountains, King Island and the Great Barrier Reef. Past students have been on the R/V Investigator, too.
Expertise related to UN Sustainable Development Goals
In 2015, UN member states agreed to 17 global Sustainable Development Goals (SDGs) to end poverty, protect the planet and ensure prosperity for all. This person’s work contributes towards the following SDG(s):
