Neil Tandon has an undergraduate degree in Electrical Engineering from The Cooper Union and professional experience as a satellite systems engineer at Boeing. In 2013, Neil obtained his PhD in Applied Physics and Applied Mathematics from Columbia University under the supervision of Prof. Lorenzo Polvani. Afterwards, he was a postdoctoral fellow in the group of Prof. Paul Kushner at the University of Toronto, funded partially by the Canadian Sea Ice and Snow Evolution (CanSISE) Network. From 2016 to 2018, he was a postdoctoral fellow in the Climate Research Division of Environment and Climate Change Canada.

Neil’s research focuses on climate dynamics. He uses a combination of models, observations and mathematical analysis to investigate how motions in Earth’s atmosphere and ocean influence climate. His work has helped to clarify the physical processes driving long-term changes in the atmospheric circulation, with implications for desertification, cloud abundance, extreme precipitation and Arctic sea ice motion. He also investigates variability in the ocean circulation and its relationship to other aspects of climate variability.
