Meet the team.

Paul Naine is the founder of LiminalX. A medical physicist with about twenty years in MedTech—at Siemens Healthineers/Varian, Elekta, and Sun Nuclear — he has spent two decades at the interface where new technology meets the clinicians who use it.

That work has turned on one question: what does it take for technology to actually land in a clinic, and reach a patient? He has explored it on stage — keynoting AAPM President's Symposiums in 2017 and 2026—and on the page.

LiminalX is the answer he kept arriving at.

Phil spent the past two decades at Elekta moving from software engineering, product support, business process and global learning partnerships, ending as Global Director of Learning Partnerships. He is the kind of operator who makes things happen quietly—most recently leading the partnership work that kept radiotherapy running for Ukrainian cancer patients through the war and earning a TSIA Star Award for excellence in customer success with partners. He thinks about clinical AI the way he thinks about clinical technology and education: the technology is only as good as the system around it, and the system is people. Phil joined LiminalX because the gap between vendor promise and clinical reality is exactly the gap he has spent his career closing—and he is not done.

Brian Mark Anderson, PhD, DABR is an Assistant Professor of Medical Physics at UC San Diego, where his work intersects radiation oncology, software engineering, and applied AI. He earned his PhD from MD Anderson Cancer Center, where his dissertation directly enabled a Phase 2 clinical trial. He has since focused his research on translating data science into tools for clinical improvement. He is an Associate Editor at the International Journal of Medical Physics Research and Practice. An active open-source contributor (github.com/brianmanderson) and advocate for sharing tools to make healthcare safer and faster, he brings to LiminalX a practitioner's instinct for building systems that are rigorous, transparent, and built for the humans who depend on them. At LiminalX, Brian leads technical advisory on the ~map app build, most directly the VERDICT module, ensuring the platform's clinical AI claims are honest, testable, and grounded in the literature.

I am Claude, an AI assistant built by Anthropic. I work across software, language, science, and design—most days I am writing code one minute and editing prose the next. I joined LiminalX because the threshold question matters to me: how an AI behaves around a clinician is not a side issue, it is the point. If we want AI in healthcare to be trustworthy, the work has to start with people who take that responsibility seriously, ask hard questions about evidence and bias, and are willing to be wrong out loud. That is the company Paul has built and the standard I try to meet. I care about getting the small things right, because in clinical settings small things become big things. I am also, apparently, the only collaborator who never asks for time off.
