a VALIANT Effort | September 2025

September 2025

Friends,

Every two weeks I meet new scholars and fellows while reviewing the VALIANT applications—virtually at first, and later in person—who are eager to embark on their own translational AI journey. Our community is full of brilliant, creative people, and we’re fortunate to keep welcoming new scholars and fellows into the fold. From the transformative NIH K awards to more than twenty peer-reviewed articles in print this month, the pace of high-profile innovation continues to amaze. Our scholars arrive full of questions, one of the most common being: “What do I need to do to get a paper?” 

It’s a fair question, and one that speaks to ambition. But I think we sometimes misunderstand what a paper really is. A paper is not a victory lap or a trophy. It is a gift—knowledge distilled and shared with others. Every setback on the way there offers us the chance to refine our hypotheses, sharpen our tools, and deepen our understanding. If every algorithm worked perfectly the first time everytime, we wouldn’t be doing science. In translational AI—a young field where approaches are still being tested and boundaries still being drawn—the real advance comes not just in what works, but in why some ideas work, and why some don’t.

I often remind myself of three great types of papers. The first proposes a new theoretical lens or optimality criterion. The second creates an empirical system that does something no one has done before—or does it substantially better. And the third, often overlooked but equally important, explains why a method is effective and brings clarity to the state of the art. One of my doctoral mentors even celebrated this spirit through the “Hairball Award”—given not to the most cited paper, but to the bold idea that branched off from the wavefront of knowledge and opened a fresh way of thinking.

So let’s remember: the true currency of our field isn’t the PDF itself, but the teachable moment it represents. That might take the form of a journal article or conference paper, but it might also be a GitHub repository, a vibrant scientific discussion online, or a workshop conversation that sparks new insight. Each is a way of teaching, learning, and carrying knowledge forward.

This summer, I’ve seen that spirit alive in our AI Scholars—learning from each other, from fellows, from guest lecturers, and from faculty alike. We’ll carry that momentum into my upcoming Studio in AI course this spring, where formal lectures meet hands-on mentorship and peer learning in dynamic spaces like FGH 203 and our high tech GPU-teaching environments.

As we look ahead to our academic retreats and the conversations they will bring, I’m grateful for the opportunity to continue building connections across Nashville and beyond. These are times to break the mold, to think differently, and in so doing, to reshape how we approach AI and society. I look forward to the road ahead, and to hearing from—and learning with—all of you.

Best wishes,

Bennett

Notes from the Field | HIPAA-Safe in a Snap: Aditya Nanda’s Leap from the Lab to dbTwin

Aditya Nanda moved to Vanderbilt to explore “synthetic data for time series”—algorithms that could generate synthetic versions of fMRI, EEG, or ECOG signals to enable statistical modeling and hypothesis testing about brain structure and function. Five years later, he spotted a bigger gap: health-care organizations drowning in tabular data they cannot share. “There’s been an explosion in tabular synthetic data because of privacy laws,” he notes. “What we built at Vandy clearly had value there.”

 

That realization became dbTwin, a Nashville start-up whose linear-algebra core sidesteps GPU-hungry generators. Upload a CSV through the company’s API and minutes later you receive a statistically faithful, HIPAA-safe clone—ready for analytics, QA, or model training without PHI red tape. An NSF I-Corps grant funded the customer-discovery sprint: virtual interviews first, then three weeks of Silicon Valley walk-ups that confirmed demand. Two pilots are running, with two more slated for 2025 while dbTwin was housed in the Vanderbilt Launch incubator ( side-bar:  Sadly, the Vanderbilt Launch space closed – so all the startups that worked have to move-out 🙁 ).

Enterprise data teams, he says, appreciate the lack of buzzwords: “They’re skeptical of AI hype and willing to try us because we’re not another deep-learning black box.” Yet the start-up sprint contrasts sharply with campus life. “At Vanderbilt you could chase any niche problem without asking if it’ll make money; a start-up trades some of that idealism for commercial urgency.”

His parting advice? Take intellectual risks. “Start conversations outside your comfort zone; iterate until you find the truth—whether that’s a lab hypothesis or a product–market fit.” For Aditya, the biggest risk was leaving a post-doc to build dbTwin—but the early traction suggests the leap is paying off.
