If you're curious about innovation, climate policy, and the energy transition but unsure where to begin, the Handbook chapter below provides a structured introduction to the field:
“The Economics of Climate Innovation: Technology, Climate Policy, and the Clean Energy Transition.” Links: Elsevier | SSRN | PDF. with Jacob Moscona (MIT). Handbook of the Economics of Climate Change. Volume 2. Elsevier. 2026. pp. 221-383. (co-edited by Lint Barrage and Solomon Hsiang).My core expertise is in clean technological change, green innovation, green industrial policy, and AI and sustainability. More broadly, my research sits at the intersection of science, innovation, and technology on one side, and sustainability, climate, and nature on the other.

At LSE, I teach lectures and seminars on the following courses:
I am also the course coordinator for GY222: Applied Environmental Economics.
I am always keen to hear from students interested in the broad questions of sustainability and technological change, particularly those working on science, innovation, clean technologies and related areas. Unfortunately, I already have a very busy schedule and receive a large number of enquiries from prospective BSc, MSc and PhD students. I am therefore generally unable to respond to individual emails about admissions, programme choice, research proposals or potential supervision. Please consult the relevant LSE programme webpages and contact the appropriate programme administrators for questions about admissions, eligibility, deadlines and the application process.
I primarily supervise PhD students through the MPhil/PhD Environmental Economics programme. In some exceptional cases, where there is a particularly strong fit with my research agenda and the proposed project is not primarily an economics project, I may also supervise students through the MPhil/PhD Environmental Policy and Development programme.
The Environmental Economics programme is designed for students pursuing research in environmental economics. Applicants should have a strong background in economics, including substantial training in microeconomics, quantitative methods and econometrics. A single economics course taken as part of an otherwise non-economics degree would not normally constitute sufficient preparation. If your background is primarily in engineering, environmental science, policy, management or another discipline, without substantial economics training, I do not recommend applying to the Environmental Economics PhD programme.
The Environmental Policy and Development programme may be a better fit for some strong research proposals that are closely related to my research interests but are not primarily economics projects. I would consider supervision through this route only where there is an especially close fit with my research agenda.
If you believe that your research proposal is closely related to my work and that I could be a suitable supervisor, please mention my name explicitly in your statement of purpose or cover letter. This helps ensure that your application is forwarded to me within the admissions system for consideration.
I am not able to meet or have informal conversations with prospective PhD applicants before applications are reviewed. Applications are considered through the Department's admissions process, and we normally shortlist candidates for online interviews around January or February. If you are shortlisted, there will be an opportunity at that stage to discuss your research proposal, research fit and potential supervision.
For questions about either PhD programme, including eligibility, application requirements and the admissions timeline, please contact the Department's PhD administrators at geog.phd@lse.ac.uk.
