Research Description:

Chris Greig is the Theodora D. and William H. Walton III Senior Research Scientist at Princeton University’s Andlinger Center for Energy and the Environment. He has a Ph.D. in Chemical Engineering, is a fellow of the Australian Academy of Technology and Engineering (ATSE), and holds an adjunct professorial appointment at the University of Queensland in Australia.


His ten-year academic career follows almost three decades of international experience in the private sector, firstly as a company founder, and then in senior executive and non-executive director roles in major engineering, energy, and resources companies. These included the CEO of ZeroGen (one of the early CCS ventures), the Deputy Chair of Gladstone Ports Corp, and the Non-Executive Director of several listed engineering firms.


At Princeton, Chris initiated the Rapid Switch Initiative at the Andlinger Center and is an Affiliated Faculty member of Princeton’s High Meadows Environmental Institute. His research combines, engineering, business, and social sciences to explore the challenges of rapid decarbonization for different regions and sectors. He is particularly focused on how to bridge modeled energy scenarios and real-world implementation. He co-led Princeton’s influential Net-Zero America (2020) study which describes five net-zero emissions pathways for the United States at an unprecedented level of detail.  Chris is also leading Princeton’s efforts on similar collaborative studies with universities in Australia, and Asia.
