Scientific Identity
Oral and maxillofacial surgeon turned systems thinker. My research program
asks a single question: how do bacterial extracellular vesicles from the
periodontal pocket drive systemic disease? The answer is the
OVN Nexus — a network medicine framework that maps theoral cavity as an upstream source node for cardiovascular, neurological,
and oncological pathology via a conserved bEV cascade.
I didn't discover that periodontal disease correlates with systemic disease.
Hundreds of studies established that. I specified the mechanism — vesicle-
mediated transport of pathological information from subgingival biofilm
to distal tissues — and built the framework that makes it falsifiable,
measurable, and protocol-generating.
The scientific thesis lives at ovnnexus.com and
is narrated in real time at the
Quantum Distillery Substack.Key Contributions
- Proposed the OVN Nexus as the organizing thesis for oral-systemic medicine
- Defined the bEV Cascade: five-step conserved
- Developed the Biomineralization Hypothesis:
- Applied network medicine to oral-
- Introduced IT-from-Qubit framing of bEV-mediated
- Created Terminal Event Pedagogy: retrograde
- 60+ peer-reviewed publications in oral-systemic pathology, surgical

Marketing Identity
As B2B/DSO Founder
Surgeon-scientist who built the science, then built the company. Gengyve
isn't a dental startup with a pitch deck — it's the commercialization of
a 20-year research program by the person who defined the field. I've
operated on over 10,000 patients, directed a surgical residency for nearly
two decades, and published the science that oral-systemic is built on.
When I tell a DSO that oral-systemic integration is an operational
advantage, I'm not selling a theory — I'm deploying a body of work that
includes 60+ publications, an R01, and a clinical protocol system tested
at UCSF and the VA. Disabled veteran founder. Nine parallel domains.
The science is mine. The protocol is mine. The company exists to
operationalize both at scale.
As Clinical Category Definer
I'm the colleague who's been in the OR and the lab for the same problem
you're starting to notice in your hygiene operatory. The connection
between periodontal disease and systemic disease isn't new — the
mechanism is. Bacterial extracellular vesicles. A conserved five-step
cascade. Measurable at every step. I defined the OVN Nexus,
built the Fasolati Triad protocol architecture,
and designed the certification pathway (Sentinel → Navigator → Integrator →
Architect) that gives hygienists and periodontists a professional identity
in oral-systemic medicine. The ADA CERP CE modules teach the mechanism
using Terminal Event Pedagogy — start
with the heart attack, work backward to the pocket. I'm not selling you
CE credits. I'm giving you the framework your practice needs for the
next decade.
As Scientific Thought Leader
The oral-systemic space has been stuck in the correlation phase for
thirty years. Hundreds of epidemiological studies showing associations.
Zero mechanistic frameworks generating falsifiable predictions. I built
that framework. The OVN Nexus specifies the transport
mechanism (bacterial extracellular vesicles), the effector program
(innate immune activation via conserved pattern recognition), and the
network topology (multi-pathogen, multi-organ, convergent pathology via
bEV-seeded interactome perturbation). It borrows from Barabási's network
medicine, Wheeler's information-theoretic physics, and complexity science's
understanding of conserved programs across scales. The Quantum Distillery
is where I narrate this work in real time — not as finished science but as
the honest middle between campfire and ivory tower.
If you're a researcher, cite the framework. If you're a KOL, engage the
thesis. If you're a VC, this is the category before the market prices it in.
