Currently, I'm the senior technology reporter covering innovation at Ars Technica. I'm also a senior lecturer in MIT's Graduate Program in Science Writing, an intensive and highly selective one-year Master's program, where I teach news reporting, editing, and digital journalism.

In 2018–2019, I spent a year at MIT as a Knight Science Journalism Fellow studying new business models for journalism as well as architecture, electrochemistry, life cycle analysis, and entrepreneurship.

Future Proof

Future Proof is the first product review site to focus on climate change. It also publishes originally reported news and commentary on climate and equity. The publicaton grew out of my time as a Knight Science Journalism Fellow at MIT, where I investigated new business models for climate journalism.

The Titan of Taiwan - June 13, 2021

When Morris Chang started TSMC in the 1980s, he had little choice but to pursue a business model that was not only unproven, but had been roundly rejected by the biggest names in semiconductor manfacturing. Over the years, though, the company not only caught up to its rivals, it surpassed them, becoming the world's leading chipmaker. But its dominance of the industry belies its precarious geopolitical position as tensions build between the U.S., the People's Republic of China, and Taiwan. Can the company maintain its edge?

Charged Up - April 11, 2021

President Joe Biden launched his term with an ambitious plan to modernize American manufacturing, and lithium-ion batteries were near the top of the list. But once before, the U.S. tried to foster a domestic battery industry, during the Bush and Obama administrations. The results then weren't promising: One high-profile recipient of government support was A123 Systems, a company that flew high for a few years only to be scooped up in bankruptcy by the Chinese auto parts giant, Wanxiang. Will Biden's battery bonanza be any different?

The Chip Choke Point - February 7, 2021

Dutch company ASML has spent 20 years and 10 billion euros refining extreme-ultraviolet lithography, a strikingly complex next-generation technology that allows semiconductor companies to make computer chips that are faster, smaller, and more energy efficient than ever before. China is desperate to get their hands on one, but they're stymied by a new ad-hoc, plurilateral agreement between the U.S., the Netherlands, and Japan, which I broke the story on. What can Chinese semiconductor companies do if they're cut off from the leading edge?

The Cobalt Empire - October 18, 2020

Over the last 20 years, China has become the dominant force in the cobalt, an industry that's a vital component of modern lithium-ion batteries in electric vehicles. One expert told me, "Whoever controls the cobalt can control how much you can decarbonize." As the world races to stave off the worst effects of climate change, will we all be dependent on China?

NOVA

As senior digital editor at NOVA, the PBS science series, I founded, edited, and wrote for NOVA Next, a digital magazine. Working with a small staff and a number of talented freelancers, I published weekly features and daily news coverage. Shortly after its launch, it became one of NOVA's most successful initiatives, eventually boosting the entire brand's site traffic by 20% and revitalizing its social media presence.
