Current EI Fellows
Ruthie Birger conducted her PhD research in the department of Ecology and Evolutionary Biology at Princeton University. She focused on HIV-Hepatitis C coinfection dynamics, using mathematical models to describe both within-patient biological processes and epidemiological impacts of public health interventions. At the Earth Institute, Ruthie will be building on these modeling methods and applying them in an effort to understand the interplay between coinfection with various pathogens and the emergence and evolution of drug resistance in populations and individuals. One of the main goals of this research will be to improve estimates of the scale of the growing problem of drug resistance, in particular in the context of global urbanization.
Madison Condon received her J.D. from Harvard University and her Masters in Law and Diplomacy from The Fletcher School at Tufts University. Her research focuses on environmental law, land and water rights, and international trade and investment law. As a Fulbright Fellow based in the Netherlands, she researched the impact of foreign investment on customary water rights in rural Tanzania. Her most recent work examines the integration of environmental treaties into trade agreements. Prior to joining the Earth Institute, Madison clerked for Judge Jane Kelly of the Court of Appeals for the Eighth Circuit. She will be working with the Columbia Water Center on a project on water use in the mining industry. She received a B.S. in Environmental Engineering from Columbia University.
Kyle received his Ph.D in Environmental Sciences from the University of Virginia. While there, he examined various human and environmental impacts of the globalizing food system and ways to make future food production more sustainable. Working with Prof. Ruth DeFries and Brian Richter (The Nature Conservancy), he will continue this general line of research at the Earth Institute. He will lead collaborative efforts to examine several case studies which highlight the multiple challenges at the nexus of food, water, and climate change. These teams will develop strategies to simultaneously increase food production, reduce the environmental cost of agriculture, and enhance the climate resilience of farmers.
Robert Elliott received his Ph.D in Civil Engineering and Engineering Mechanics (CEEM) from Columbia University. During his time at the Earth Institute, he will be researching how to update contemporary infrastructure with eco-technical systems and apply engineering principles observed in living systems to develop more sustainable environments. Specifically, he will work with an interdisciplinary team of scientists to focus on the ability of green infrastructure to improve urban health and livability while mitigating environmental pollution. Projects include designing next-generation green infrastructure components, measuring the efficacy of extant green infrastructure, and multi-scale modeling of various ecosystem services. Robert holds a B.S. in Civil and Environmental Engineering from Lafayette College.
Xiaohui received her Ph.D. in Plant Biology from the University of Illinois at Champaign Urbana. Her dissertation research investigated the productivity, physiology, community dynamics, and ecological impacts of a grassland agro-ecosystem combining field studies and ecosystem modeling. At the Earth Institute, she will be working with Dr. Maria Uriarte to improve our understanding of global carbon cycle. As a field ecologist and modeler, her research will focus on the investigation of the interactions and feedbacks of tropical forests with climatic changes. Her research goals are to quantify the responses of tropical forests to climate variability including drought, warming and hurricane disturbance and to improve the predictive capacity of terrestrial ecosystem models. Her work will identify the critical scientific gaps and key processes in tropical forest studies, and thus lead to significant improvement in the representation of tropical ecosystems in terrestrial carbon models.
Alexandra (Alex) Karambelas received her Ph.D. in Environment and Resources from the University of Wisconsin—Madison. Alex’ research focuses on the links between energy, emissions, air quality, and human health outcomes. During her time at The Earth Institute, Alex will work with Drs. Ruth DeFries, Arlene Fiore, and Patrick Kinney to evaluate these connections in northern India. Through this research, she seeks to quantify contributions from various anthropogenic emissions sectors to ambient pollution concentrations and human health outcomes in the region and determine potential sectors for future mitigation. Alex also holds degrees in Atmospheric and Oceanic Sciences (B.S., M.S.) and a certificate in Energy Analysis and Policy from the University of Wisconsin—Madison.
Milad Kharratzadeh received his Ph.D. from McGill University in 2016. His dissertation developed novel multivariate regression schemes with real-world applications. He obtained his M.Eng from McGill University (2012) and his B.Sc from Sharif University (2010). While at the Earth Institute, he will be working with Andrew Gelman, professor of statistics and political science and director of the Applied Statistics Center. Milad will be focusing on the use of hierarchical Bayesian models for analysing environmental, social, and health data. He will also collaborate with researchers at the Data Science Institute at Columbia University.
Ding Ma received his Ph.D in Earth and Planetary Sciences from Harvard University. His dissertation research investigated three dominant patterns of large-scale atmospheric variability, namely the South Asian monsoon, Madden-Julian Oscillation and the annular mode. At the Earth Institute, he will be working with Prof. Adam Sobel to explore extreme weather associated with large-scale variability and its societal impacts. His work will emphasize a combination of observational analysis and numerical modeling. Guided by observations, numerical experiments will be designed and conducted to pursue a better theoretical understanding of the large-scale atmospheric variability in the past, present and future. His work will identify essential physical mechanisms governing the large-scale circulation variability and will have important implications for interpretation of climate projection.
Mankin is a climate scientist jointly appointed at Lamont-Doherty Earth Observatory and the Center for Climate Systems Research under the Earth Institute. His research aims to advance understanding and responses to global warming’s impacts on people. He focuses on two of the major sources of uncertainty in climate impacts assessments: the chaos innate to the climate system and the complexity of how people respond to climate stress. His hope is that his research can help inform the adaptation and risk management decisions that people undertake in response to the uncertain threats from climate change. Prior to earning his PhD from Stanford’s School of Earth, Energy & Environmental Sciences, he served as an intelligence officer. He also holds degrees from Columbia University (BA, MPA) and the London School of Economics (MSc).
Hannah Nissan is a climate scientist from London. Originally a physicist by training, she holds a postgraduate degree in economics and a PhD in regional climate modelling from Imperial College London. At the Earth Institute she will work jointly with scientists at the International Research Institute for Climate and Society and the Red Cross Red Crescent Climate Centre to develop climate change projections for disaster risk reduction programmes in Bangladesh. A key focus of her research will be to examine how this knowledge, and in particular the uncertainty surrounding climate projections, can best be communicated to decision makers.
Nandini Velho has done field work in remote areas in north-east India, where her PhD focused on how protected area and community-managed lands are managed to reduce hunting and help wildlife persist. She works closely with the forest department, resident communities and writes in popular media. She completed her Ph.D. from James Cook University, Australia. As an EI fellow, she will be working with Ruth DeFries to understand the social and health outcomes that exist in and around India’s protected areas.
