Faculty, students, and staff across Columbia are engaged in important research and action around these vital concerns.
Research Areas: Machine learning, carbon water fluxes, solar induced chlorophyll fluorescence, remote sensing.
Research Areas: Stochastic modelling for hydro-meteorological risks: frequency analysis, extreme value theory, Bayesian approaches, machine learning methods, uncertainty analysis; Water-energy-food nexus and its relationship with climate; influence of large scale climate variability on extreme events; current and future climate risks on coastal cities; operation and management of reservoirs and dams.
Research Areas: Dr. Troy’s research lies at the intersection of climate, water, and food, with a particular interest in understanding the role of climate variability on water supply and demand across a variety of scales. To do this, she uses a computational hydrologic model, remote sensing, in situ measurements, and reanalysis products with work focusing on developing numerical models that include human activities, such as irrigation, and high resolution flood modeling.

Research Areas: Studies the interactions of the hydrologic cycle with climate, terrestrial ecosystems, and society – interactions that are important for climate, natural and built environments, food security, and human health. Examines land-atmosphere interactions with the GISS climate model and advises the United Nation Development Programme on climate change information.

Research Areas: Drinking water issues in rural and developing areas of the world, America’s water quality compliance and policy, and fluoride and arsenic treatment
Dr. Joseph Graziano's research career has been devoted to understanding the consequences of exposure to metals, both on the molecular and population levels. More recently, Dr. Graziano's work has taken him to Bangladesh, where his current research is aimed at understanding the consequences of arsenic exposure on the Bangladeshi population, and on devising strategies to reduce toxicity and provide arsenic-free drinking water, a problem that spans beyond the political borders of Bangladesh, to much of South Asia, from India to Vietnam. Recent findings that both arsenic and manganese, both elevated in Bangladesh drinking water, are associated with cognitive deficits in children, add urgency to solving this enormous public health and environmental problem.
Research Areas: feedback between environmental and human systems, focusing on the impacts of climate change and the water-energy-food nexus. Integrated modeling, climate change impacts, techniques in complexity, and social change innovation.
I am an adjunct professor teaching visual narratives at the J-School with Nina Berman. Rising sea levels and their impact on communities has been a major focus of mine for over 2 decades. I have worked extensively in Fukushima following the 2011 tsunami and resulting nuclear meltdown, documented the devastation in Houston during Hurricane Harvey and, closer to home, focused on towns in Staten Island post Sandy amongst many other places on our planet. When there is a moment I'd very much like to come by to get a greater understanding of what you have planned for The Year of Water and how my work might be able to fit in with your program. I am particularly interested in your multidisciplinary approach to addressing climate and water issues. I frequently work with scientists and artists to address climate change and have widely exhibited that work.
Most recently I projected just down the block at St. John the Divine that wove together dance, poetry and traditional Japanese flute with my moving images and ambient recordings from the Exclusion Zone. My Fukushima work was an official selection at the 52nd New York Film Festival where my team and I created an immersive exhibition.
