My background is in climate, atmospheric science and hydrology, as well as biology. I study the environmental determinants of infectious disease transmission. In particular, I investigate how atmospheric conditions impact the survival, transmission and seasonality of pathogens and how hydrologic variability affects mosquito ecology and mosquito-borne disease transmission. More broadly I am interested in how meteorology affects human health. I am now working to develop systems to forecast infectious disease outbreaks at a range of time scales. In addition, I study a number of climate phenomena, including Rossby wave dynamics, atmospheric jet waveguides, the coupled South Asian monsoon-ENSO system, extratropical precipitation, and tropical cyclogenesis.

Zachary Burt earned his PhD at the Energy and Resources Group at the University of California, Berkeley in 2015. He is interested in the techno-social systems which manufacture and allocate risk, and how these play out in the water and sanitation systems of low, middle and high income countries. He has researched the costs and benefits of urban water service improvements, willingness to pay for household water treatment and gender inequities in sanitation access. He has conducted field research in India, Tanzania, and Kenya, and assessed urban water policies in California, India and Kenya. At Columbia, Zach researches efficient, effective and equitable ways of incorporating climate risk into urban water management policy in low income countries, especially focusing on water and sanitation access for marginalized groups.
