When the pandemic hit, I left my research career to serve the public as a science and tech expert in our federal government. In the U.S. Senate, I fought corruption and helped write bipartisan laws that invest in safer communities, clean water, and good-paying union jobs. At the National Institutes of Health, I worked to expand access to health care. And at the U.S. Government Accountability Office, I helped Congress use facts to solve real-world problems, protected your hard-earned tax dollars from waste, and served as an elected union leader to stand up for hundreds of federal workers.
