I've worked on a number of white papers and workshop reports for the Computing Research Association's Computing Community Consortium, an organization that I chaired for a number of years. Here are some of those resources; you can find more under the "Resources" tab of the CCC website listed above.

• “Computing Research for the Climate Crisis"
• “Building Resilience to Climate Driven Extreme Events with Computing Innovations: A Convergence Accelerator Report"
• “Fostering Responsible Computing Research Report Recommendations for Computing Research Institutions: Actionable Steps"
• “An Agenda for Disinformation Research” (press release here),
• “Pandemic Informatics: Preparation, Robustness and Resilience"
• "A 20-Year Roadmap for AI"
• “Big Data, Data Science, and Civil Rights" (and related blog post).

Some publicity/thought pieces in other venues:

• A 2020 College of Engineering article about the work of the Computing Community Consortium (CCC).
• A 2020 podcast from the CCC about our group's work on ice cores and chaos theory.
• A 2022 article and a 2023 podcast from Nature about being a scientist, teacher, mentor...and athlete.
