ROMEO results

Research Outline

I am interested in understanding the mathematical tools used to model oil depletion at large scales. I also have worked on modeling the transition to substitutes for conventional oil in the face of resource depletion. These tools will help us understand which oil substitites might be used in the future, how quickly and extensively we might need to develop them, and what their impacts could be.
