Preeti joined Burness in 2000 and has since become a leading global health and international development communications strategist. She advises organizations such as the American Society of Tropical Medicine and Hygiene, Gates Medical Research Institute, Johns Hopkins Bloomberg School of Public Health, Nuclear Threat Initiative, Medicines Patent Pool and TB Alliance on how to advance their issues globally.

She has helped develop and execute communications strategies to support the nonprofit development of vaccines for malaria and tuberculosis and novel drug regimens for TB, expand access to HIV treatments in low- and middle-income countries, and introduce vaccines in countries like Burkina Faso and Pakistan. She has led press operations at major scientific conferences such as the Multilateral Initiative on Malaria meetings held in Africa and the American Society of Tropical Medicine and Hygiene annual meeting; supported a climate justice campaign that secured a legal victory at the International Court of Justice; advanced climate change solutions rooted in changes to our food system; raised the media profiles of global health security experts and more. Her deep knowledge of the global health and climate space has enabled her to create a network of journalist contacts spanning the globe — from Johannesburg to London to New Delhi to New York.

Before joining Burness, Preeti studied at Tufts University and the University at Albany and worked for a nonprofit organization serving the neurologically disabled.
