Prior to the NMF, Pushp has worked as an independent science writer and researcher focusing on climate change and the environment. He has written several articles on climate science, sustainable energy, climate policy, and related areas, for major Indian news outlets. He has interned at the Center for Science and Environment, New Delhi. He has a PhD in Chemistry from the University of California, San Diego where he was a graduate student researcher for the NSF-funded CCI Center for Aerosol Impacts on Chemistry of the Environment based in San Diego, CA, USA.
