The AAAS Mani L. Bhaumik Award for Public Engagement with Science, formerly the AAAS Award for Public Understanding of Science and Technology, was established in 1987 to recognize scientists and engineers who demonstrate excellence in their contribution to public engagement with science. The recipient receives a monetary prize of $5,000, a commemorative plaque, and recognition at the AAAS Annual Meeting. Public engagement activities emphasize dialogue with various publics and often result from a public interaction, request, or need. Specifically, these activities are defined as the individual’s active participation in efforts to engage with the public on science- and technology-related issues and promote meaningful exchanges between science and society, as highlighted here.
