These power plants are Colorado's biggest greenhouse gas emitters. Here's where they stand

Publication: The Coloradoan

Brief: Over the past decade, the 10 largest emitters in Colorado contributed to an outsized share of greenhouse gasses — and every single one is a fossil fuel power plant. While the parent companies that own them are driving the state's reductions, it might still not be enough for the state to reach its climate goals.

Publication: USA TODAY

Brief: I applied voting data from the 2024 presidential elections to the newly-drawn districts in California to simulate the impact these changes could bring.

Publication: The Coloradoan

Brief: In Colorado, the top 20 largest wildfires happened this century, and four of the five largest wildfires happened since 2018.

Chicago’s one-star nursing homes were troubled before the pandemic. Now, they’re ‘ground zero’ 

Publication: The Columbia Chronicle

Brief: In a first-of-its-kind analysis, we scraped data from several sources to examine how nursing home residents were being impacted at the beginning of the COVID-19 pandemic. We found that not only was there a disproportionate number of cases and deaths in these facilities, but the ratio of COVID-19 deaths per facility was the highest at at low star facilities (oftentimes found on disadvantaged neighborhoods) on the federal ranking.
