After completing a business degree majoring in finance at Murdoch University, Perth, Jemma joined J.P. Morgan in London. One of the biggest challenges at the time was the explosion in exotic and hybrid equity derivatives which was bringing in $700 million profit annually for the bank. This scalability challenge demanded an automated systems response, and Jemma oversaw a large software development project to achieve this. Developing, delivering and implementing the project with a 25 strong team across different time zones became a norm and after a decade, the system is essentially the same and still performing.

Looking for a fresh challenge, Jemma got involved with setting up the new Global Environmental Risk function at J.P. Morgan. This was something that investors were increasingly demanding and the new function launched in 2007.

During that time she also completed two post-grad diplomas in sustainability with a Masters at Cambridge University. She returned to Perth in 2013 to do a PhD in electricity market disruption at Curtin University.

This PhD was in effect an embryonic Power Ledger project, and she and her co-founders set up the new venture on a commercial footing. Since then, Jemma has overseen the development of numerous software projects that integrate blockchain technology with transactive and market layers. Clients have included Ekwateur in France, M-RETS in the USA, and 12MW Thailand TDED.
