After graduation, Tuna became a reporter for
The Wall Street Journal, where she covered topics including enterprise technology, the
California economy, and corporate management. In 2011, Tuna quit her job at
The Wall Street Journal to focus on philanthropy full-time. Tuna has stated that she chooses philanthropic cause areas to support based on their "neglectedness, importance, and tractability (how hard it might be to solve)." Since its founding, Coefficient Giving has directed more than $4 billion in grants across a variety of focus areas, including
global health, scientific research,
pandemic preparedness, potential
risks from advanced AI, and
farm animal welfare. Tuna was included in ''
Time's'' "100 Most Influential People in AI 2024" for her role at Coefficient Giving. She was also recognized by
Melinda French Gates as one of six women "making philanthropic strides", saying that Tuna's "experience as a journalist has informed her approach", adding that she is "rigorous about looking at the data and figuring out how to be as effective as possible." == Personal life ==
