Current Students

Jieyi is a Ph.D. student in the Science, Technology, and Environmental Policy (STEP) program at SPIA. She earned a bachelor’s degree in public relations from Sun Yat-sen University but was curious about environmental and energy issues. Driven by her curiosity, she obtained a master’s degree in public policy from Georgetown University studying environmental and energy policy and a master’s degree in environmental science from Yale University focusing on the impacts of air pollution on different groups of people. She also worked as a research assistant at Resources for the Future in Washington, D.C., conducting research related to China’s emissions trading system and applications of satellite data. At Princeton, she hopes to further investigate and develop solutions to improve both the environment and human wellbeing in the developing world.

Prior to attending Princeton, Jack graduated with a master's degree in environmental science from Yale School of the Environment. His master's thesis examines the Chilean Constitutional Convention of 2022, considers its environmental justice implications, and addresses the rejection of the proposed constitution. Jack graduated summa cum laude with a Bachelor of Science from Furman University, where he majored in sustainability science and Spanish language and literature, with a minor in Latin American and LatinX studies. His undergraduate thesis maps ecosystem services geographically and examines policy mechanisms that contribute to differing levels of ecosystem service provisioning. He has additionally earned an Associate of Arts from Greenville Technical College. At Princeton, Jack will continue to research environmental justice policy and compare policies from various international contexts.

Malini is a Ph.D. student in the Science, Technology, and Environmental Policy (STEP) program at Princeton’s School of Public and International Affairs. Malini grew up in Frederick, Maryland, and holds a Bachelor of Science degree in environmental engineering from Columbia University. Prior to Princeton, Malini was based in San Francisco, where she was a senior consultant at Ramboll, specializing in air quality modeling, climate change mitigation, and human health risk assessment. Her research is focused on the deep decarbonization of the power sector in India, and she uses the tools of power system modeling and air quality modeling to understand the air-climate-health tradeoffs of electricity policy choices.

Wahyu's research interests lie in conservation science and policy, with particular emphasis on conservation social science and wildlife trade topics. Prior to joining Princeton, he worked for several international organisations as a researcher looking at various conservation issues, including illegal wildlife trade, illegal logging, REDD+, and voluntary carbon markets. He holds an MSc in biodiversity, conservation, and management at the University of Oxford (Mansfield College) as an Oxford-Islamic Development Bank (IsDB) Scholar, where his dissertation applied conservation criminology to explore wildlife crime in Indonesia. He received a BSc in geography with a major in cartography and remote sensing from Universitas Gadjah Mada (UGM), Indonesia.

Oladoyin is from Lagos, Nigeria, but went to high school in South Africa and Wales. Her undergraduate studies at Princeton University were in operations research and financial engineering. She is interested in energy planning to increase access to energy and industrialisation in sub-Saharan Africa. Her work specifically considers the realities around the political economy and the need for transition to low carbon technologies. Before starting her STEP Ph.D., Oladoyin completed a master’s in operations research and information engineering at Cornell University. She also worked in Mumbai, India, as a data analyst, and in London as a data engineer before recommitting to her passion to see Africa rise. When she’s not thinking about her research, she’s writing on her blog, yenuwo.com where she expresses her creative and introspective side.
