A spilled Caesar salad changed my life.

It was an early spring afternoon at Amherst College when I heard rumors that Ronald Reagan was in town with his teenage son on a college tour. Armed with nothing but a tape recorder and undergraduate audacity, I tracked down the future president at the Lord Jeffery Inn. Though he declined my interview request, he invited me to dinner instead.

Sitting across from Reagan in that hotel restaurant, nervously fumbling with my salad, I experienced something profound. Here was a man who would eventually end the Cold War, genuinely interested in the views of a young center-left chemistry major. In that moment, I felt the intoxicating rush of being “on the center stage of history in the making”—a feeling that my parents’ Caltech lab could never provide.

That dinner was my first taste of what I now call being a science ambassador.

The Winding Path from Bench to Beltway

My journey wasn’t linear. After that Reagan encounter, I collected experiences with public figures like Jimmy Carter and Edward Kennedy, even managing Maria Shriver’s father’s unsuccessful presidential campaign in western Massachusetts. But I still pursued the traditional academic path, earning my neuroscience doctorate at the University of Michigan after a false start at UC Irvine, where I’d been distracted by serving as graduate student body president—twice.

The real turning point came during my postdoc at the National Institutes of Health. Despite doing excellent science just twelve miles from the U.S. Capitol, I was denied tenure. My work wasn’t considered independent enough from my mentor. It was painful, but it became career-making.

Suddenly needing employment, I landed what seemed like an impossible job for a postdoc: executive director of the American Association of Anatomists. I was managing a million-dollar budget and working as a full-time science ambassador, but I missed the actual science and felt constrained by the “glass ceiling” that comes with being permanent staff at a scientific society.

So, I made another leap—to Institute Director and full professor at George Mason University’s Krasnow Institute. I’d bypassed the traditional tenure track entirely because my employer needed someone with both academic credibility and administrative experience. Over sixteen years in that role, I raised significant funding, built laboratory expansions including a human brain scanner, and began playing in the major leagues as a science ambassador.

The Moonshot Moment

The defining experience came in 2007 when I led a group proposing a $3 billion project that would eventually become President Obama’s BRAIN Initiative. The pivotal moment was a lunch at Google’s Mountain View headquarters with Tom Kalil, who was heading Obama’s science transition team.

I thought the meeting went terribly. Kalil asked tough questions our group hadn’t considered, particularly about success metrics. He pointed out that the Apollo program had a clear goal: land a man on the moon and bring him safely back. What would be our equivalent “moonshot” moment?

That lunch taught me a crucial lesson: it’s not enough to identify a compelling policy problem. A public intellectual must offer a persuasive trajectory to success and appropriate metrics to prove it. To my surprise, that apparently disastrous meeting was ultimately successful and became foundational to my understanding of science diplomacy.

From Government to Academic Practice

When Obama rolled out the BRAIN Initiative at the White House, I was brought in to head biological sciences at the National Science Foundation. This role allowed me to fully instantiate my identity as a science ambassador. I received media training, testified before Congress, had regular White House meetings, and found myself walking along an Arctic Ocean beach with beautiful black sand and no ice—the full experience of being a science ambassador in action.

Returning to George Mason in 2018, I landed not back at the Krasnow Institute, but at the Schar School of Policy and Government. I was no longer a disciplinary scientist; I had become something different. Within a week of returning, I received my first grant from the U.S. Air Force to analyze what AI would look like for the force in 2030. The seminal paper on large language models had just been published, and AI was clearly becoming a major policy issue.

Why This Book Matters Now

I wrote this book because there’s a critical shortage of scientists serving as public intellectuals, and the need has never been greater. The STEM doctorate labor market is distorted—far more qualified candidates exist than tenure-track positions. This creates an opportunity for scientists to leverage their credentials in new ways, becoming influential voices on the global stage.

The book serves as both roadmap and survival guide for scientists ready to transition from bench or field work to public intellectual roles. Whether you’re dealing with climate disruption, food security, geopolitical instability, or—like me—neural diversity and AI policy, you can develop a constantly adapting portfolio of issues to write and speak about.

The transformation isn’t just professional; it’s personal. Being a science ambassador means having credibility to influence the primary science issues of our time, whether through social media, podcasts, or testimony before legislative bodies. Some will undergo complete metamorphosis, leaving bench science entirely for governmental positions, non-profit sector roles, or academic practice like mine.

The world needs scientists who can translate complex research into compelling narratives for policymakers and the public. We need advocates who understand both the intricacies of scientific discovery and the realities of political process. We need science ambassadors.

That spilled Caesar salad was just the beginning.
