  • Choquette-Levy, Nicolas

    Princeton School of Public and International Affairs

    Choquette-Levy is in the Princeton School of Public and International Affairs’ Science, Technology, and Environmental Policy program. His research focuses on the links between climate change and rural-urban migration in developing country contexts, with regional interests in Nepal and China. He is applying agent-based modelling and systems analysis methods to better understand how smallholder farming communities are using migration as a way to adapt to climate change, and how farmers’ social networks influence their decision-making around adaptation.

  • Crawford, Chris

    Princeton School of Public and International Affairs

    Crawford is studying how changing spatial patterns of agricultural land use are likely to affect biodiversity. In particular, he  focuses on areas of agricultural decline and abandonment to try to understand whether they represent opportunities for the conservation of biodiversity, and how to use policy to guide these transitions. Crawford is in the Science, Technology, and Environmental Policy (STEP) program in the Princeton School of Public and International Affairs and is advised by David Wilcove, professor of ecology and evolutionary biology and public affairs and the Princeton Environmental Institute.

  • Cruz Álvarez, José


    Cruz Álvarez is based in the Economics Department. His research attempts to build a bridge between the regional integrated models of climate change and the quantitative models of international trade and the migration frameworks. In particular, his work provides a tractable framework to investigate the spatial impact of climate change in a dynamic context, as well as the optimal CO2 tax under different degrees of cooperation across countries.

  • Eardley, Megan


    Eardley, who is in the School of Architecture, focuses her work on how the “environment” emerged as a global paradigm in the second half of the 20thcentury, and how this paradigm reconfigured colonial ideas about climate, wealth, race and morality.

  • Hajirezaie, Sassan

    Civil and Environmental Engineering

    Hajirezaie works with Professor Catherine A. Peters, Chair of the Department of Civil and Environmental Engineering where he focuses on developing approaches to control the migration of fluids in subsurface technologies such as geothermal energy production, subsurface remediation, oil and gas production, and energy storage. Hajirezaie is investigating the conditions that could lead to the precipitation of minerals in underground fractures, and the impacts of precipitation on fracture hydraulic properties and carbon dioxide leakage.

  • Hartzell, Samantha

    Civil and Environmental Engineering

    Hartzell focuses her research on understanding the ecohydrology of water-limited ecosystems, including deserts, tundra and rainforest canopies. She is particularly interested in Crassulacean acid metabolism, or CAM photosynthesis, which is an ecological adaptation that affords plants in arid conditions a 500 percent increase in water-use efficiency. Her adviser is Amilcare Porporato, the Thomas J. Wu ’94 Professor of Civil and Environmental Engineering and professor of civil and environmental engineering and the Princeton Environmental Institute.

  • Luxem, Katja


    Luxem works in the geosciences department’s Microbial Biogeochemistry Lab studying how microorganisms produce nitrogen fertilizer. Her adviser is François Morel, the Albert G. Blanke, Jr., Professor of Geosciences and the Princeton Environmental Institute, Emeritus, and Senior Scholar

  • Murphy, Jack


    Based in geosciences, Murphy examines the history of the geologic carbon cycle and the evolution of Earth’s climate on geologic timescales. He is advised by John Higgins, associate professor of geosciences.

  • Raghuraman, Shiv Priyam

    Atmospheric and Oceanic Sciences

    Raghuraman, who is in the Program in Atmospheric and Oceanic Sciences, aims to understand the causes of energy imbalances in the atmosphere and how these imbalances impact the climate. His research focuses on the radiative forcing of the most important greenhouse gas — water vapor — which has a strong positive feedback on the climate system. He is advised by V. “Ram” Ramaswamy, director of the Geophysical Fluid Dynamics Laboratory and a Princeton lecturer with the rank of professor in geosciences and atmospheric and oceanic sciences.

  • Smyth, Jane

    Atmospheric and Oceanic Sciences

    Smyth investigates the physical controls of tropical rainfall variability using climate models of varying complexity. Her research focuses on monsoons, large-scale systems that supply the majority of annual precipitation to land regions across the tropics. An improved mechanistic understanding of monsoon seasonality will enable better projections of how climate change may impact rainfall patterns. Smyth’s advisor is Yi Ming, Deputy Head of the Atmospheric Physics Division at the NOAA Geophysical Fluid Dynamics Laboratory.

  • Stein, Serena


    Stein, in the Department of Anthropology, studies the cultural and environmental dimensions of international development, agribusiness and food security, as well as the energy sector and extractive economy in Southern Africa.

  • Su, Yibing

    Civil and Environmental Engineering

    Su is in the Department of Civil and Environmental Engineering where she studies hydrometeorology. Her research focuses on addressing the question of how hard it can rain at time durations critical to urban watersheds. Su develops hydrometeorological procedures to analyze the physical mechanisms and variables producing extreme short-duration rainfall and gain insight on the upper physical bound to rainfall intensity. A specific focus has been paid on Extratropical Cyclone systems given their destructive potential in producing extreme rainfall and flooding.

  • Sun, Emily

    Civil and Environmental Engineering

    Sun works in the group of Ian Bourg, assistant professor of civil and environmental engineering and the Princeton Environmental Institute, studying multiphase flow at the interfaces of minerals, water, carbon dioxide and organics, with the goal of understanding fundamental phenomena and improving predictive capabilities in carbon cycling.

  • Tao, Yiheng

    Civil and Environmental Engineering

    Based in the Department of Civil and Environmental Engineering, Tao works  with Professor Michael Celia. Tao is interested in analyzing energy development and climate change mitigation from engineering, policy, and economic perspectives. Specifically, his research focuses on numerical modeling of carbon dioxide injection into deep geological formations, carbon emissions implications of China-proposed Belt and Road Initiative, and the viability of carbon capture and storage technologies in the U.S. and China.

  • Teitelbaum, Eric


    Teitelbaum is in the School of Architecture. His research investigates materials for energy-efficient comfort systems for the built environment, including new materials and processes for evaporative cooling and exciting new technologies for radiant cooling.

  • Tracey, John


    Tracey studies the biochemistry of the marine nitrogen cycle.  His research focuses on anammox bacteria that produce toxic intermediates to power their cells, deploy fatty acids to guard against these toxins, and evolutionarily date to near the root of the tree of life. Some anammox bacteria have small protein compartments, dubbed encapsulins, that might enclose some of the toxin producing enzymes central to the anammox metabolism.  Through this research, Tracey seeks to elucidate the function of encapsulins using in-vitro experiments.

  • Wilson, Jessica

    Wilson studies diffusiophoresis (the spontaneous movement of a colloidal particle in a chemical gradient) and wetting phenomena.  She works in the Complex Fluids Group and is advised by Howard A. Stone, the Donald R. Dixon ’69 and Elizabeth W. Dixon Professor of Mechanical and Aerospace Engineering, professor of mechanical engineering and chair of the Department of Mechanical and Aerospace Engineering.
