I thoroughly enjoyed this timely conversation on the effective adoption of AI tools for military applications.
Earlier this month, CMIST’s Mieke Eoyang & Harry Krejsa convened a public-private workshop on AI deployment in military mission spaces. Joined by Perri Adams (formerly DARPA) & Thomas Serban von Davier (SEI), the workshop identified barriers to effective adoption across defense.

Cutting edge technologies could be game changers for U.S. allies in Asia—but Cold War defense export rules are holding them back.

CMIST’s new paper makes the case for defense export reform as the next frontier after acquisition reform.

“If we’re in a contingency, shipping energy over the ocean in a contested environment... then we need to think about what kinds of energy technologies are available that are resilient to blockade,” @harrykrejsa.bsky.social tells The Wire China. Read more www.thewirechina.com/2025/09/28/t...
Taiwan’s Achilles’ Heel - The Wire China
Taiwan is almost entirely dependent on imported fossil fuels for its energy supply — a critical weakness in the event of a Chinese blockade.

I spoke with the Washington Post about remarkable new research suggesting DeepSeek will produce code with major security flaws much more often depending on who you tell it the software is for.

AI firm DeepSeek writes less-secure code for groups China disfavors
Research by a U.S. security firm points to the country’s leading player in AI providing higher-quality results for some purposes than others.

Batteries are increasingly linking the defense & modern energy sectors. If “tree huggers” and “dragon slayers” join forces, America can reindustrialize on stronger footing. Sarah Hipel & I make the case today in our @washingtonpost.com op-ed.

The hurdles to marrying clean tech and the defense industrial base are cultural more than technical.

I enjoyed discussing advanced chip exports to China with The Guardian, and why dismissing NVIDIA H20s as "obsolete" misunderstands the increasingly inference-intensive direction of the AI market.

Trump sparks concern after suggesting he might allow sales of Nvidia’s advanced AI chips in China
President says he could make deal for Nvidia to sell downgraded version of Blackwell chip in China but expert warns that could help Beijing compete in AI

New from CMIST + SEI:

In our new white paper, Harry Krejsa & Thomas Şerban von Davier explore how slashed inference costs and openly-distributed models are transforming AI's future—economically, politically, and how we build the systems that power it.

I was thrilled to be back in Taiwan speaking at DSET's National Strategic Summit on Supply Chain Resilience. I appreciated the opportunity to discuss shared US-Taiwan interests in energy and tech security as the AI race heats up.

AI's energy demands are making our grid an even more tempting target for cyberattacks. Mark Montgomery and I argue in our new op-ed that clean tech & advanced transmission can make our grid more defensible & resilient to these attacks while fueling our race for AI advantage.

Chris Barnard and I argue in our new op-ed that, when it comes to fueling our AI competition with China, Texas seems to be the only state that has figured out how to generate the electricity necessary to meet the moment.

Last week, CMIST hosted Masaryk University’s delegation in DC for the Cyber 9/12 Strategy Challenge. The group engaged in discussions on cybersecurity policy, emerging threats, and potential U.S.-Czech research collaboration.

I was thrilled to join the latest episode of Volts to discuss how clean energy technologies can be uniquely capable of defending our grid against PRC attack, how best to integrate the "peaceniks and natsec hawks," and where clean tech, AI, and national security could pave the road to abundance.

My first report for Carnegie Mellon's Institute for Strategy & Technology explores how clean energy is uniquely capable of fortifying our infrastructure against PRC cyberattacks — but only if the national security and clean tech communities realize their common cause.
