Role: Second year PhD student, Centre for Environmental Policy, Imperial College London

Subject area: Socio-economic impact of net zero transition pathways

Nationality: Chinese

I am a second year PhD student at the Centre for Environmental Policy. My research focuses on the socio-economic impact of different ways the world can reach net zero carbon emissions. I'm originally from China, and I spent seven years in the United States for high school, undergraduate study and work before I moved to London.

Hear from Judy, who is working on using scientific evidence to help policy makers understand the impact of their policies on society in order to get to net zero carbon emissions.

Detail about Scott


My research

I use computer modelling to look at the impact of implementing routes to a net zero world, specifically the impacts on society and cost implications. My work can help policymakers design energy and climate policies while ensuring quality of life and fair distribution of the societal burden envolved. 

My inspiration

My inspiration

I saw first-hand the drastic environmental change each year when I returned home to China during my studies. This sparked my interest in tackling the global challenge of providing the energy for the development of our society and doing so sustainably.

My STEM hero

Former US president Jimmy Carter, who established the US Department of Energy and installed rooftop solar panels on the White House for the first time. This paved the way for supporting important energy research.

Most significant scientific discovery?

Haber-Bosch Process. It allowed for massive enhancements in fertilizer production for crops (although it did have a horrible war-time history).
