Research & Clinical Validation

Evidence in
progress. Honest
about where we are.

Vasl's research program is in its early stages — which is the honest description of where we are. We have one active IRB study, one active data collaboration with Mayo Clinic Platform, and a clinical advisory relationship with Johns Hopkins. Peer-reviewed publication is in progress. That's what we know. It's enough to build on.

Chapter 01 — Active Research

Two active
collaborations.

Both are operational — not announced, not aspirational. The University of Maryland IRB study is in active data collection. The Mayo Clinic Platform_Accelerate collaboration is in its first year of a two-year arc. These are the two research foundations that underpin every VLAP accuracy claim on this site.

VLAP Clinical Signal Validation Study — University of Maryland

An IRB-approved study validating CulturalBERT-VLAP's signal detection accuracy against clinician-adjudicated ground truth assessments. The study uses production deployment data from live Vasl cohorts — real members, real language, real clinical annotations by licensed clinicians with community competency training. This is the primary independent validation of VLAP's culturally specific signal detection capabilities. Results will be published in a peer-reviewed journal upon study completion.

Mayo Clinic Platform_Accelerate — Two-Year Data Collaboration

Vasl Health is an active participant in the Mayo Clinic Platform_Accelerate program. The collaboration provides access to de-identified behavioral health data infrastructure for VLAP model development and validation. The two-year arc is structured specifically to support CulturalBERT-VLAP's NLP training, validation, and LEP (Limited English Proficiency) population baseline work — with Year 1 focused on model development and Year 2 on prospective validation.

Institutional
grounding.

The research program is grounded in three active institutional relationships — each with a specific, documented role. These are not advisory relationships in name only. Each involves ongoing operational work, clinical oversight, or data access that directly informs VLAP's development and validation.

Mayo Clinic
Health System · Research Accelerator
Mayo Clinic Platform_Accelerate — Active Participant

Access to de-identified behavioral health data infrastructure for CulturalBERT-VLAP model development and validation. Two-year structured collaboration — Year 1 model development, Year 2 prospective validation. Provides the data scale necessary for VLAP's NLP training on longitudinal behavioral health signals at clinical population level.

Active IRB Study — VLAP Signal Validation

Independent academic validation of VLAP signal detection accuracy through an IRB-approved study comparing CulturalBERT-VLAP output against clinician-adjudicated ground truth. The study represents the first formal independent validation of VLAP's culturally specific signal detection capabilities. Results will be published in peer-reviewed literature upon completion.

Medical School · Clinical Advisory
Senior Medical Advisor — Clinical Validation Oversight

Panagis Galiatsatos, MD, MHS — Assistant Professor of Medicine at Johns Hopkins University School of Medicine — serves as Vasl Health's Senior Medical Advisor. Dr. Galiatsatos provides clinical oversight on VLAP's signal detection methodology, accuracy validation approach, non-diagnostic output framing, and the clinical governance of the platform's care coordination model. Active involvement — not nominal affiliation.

Advisory
Chapter 03 — Research Principles

How we conduct
research.

Four principles that govern every research decision Vasl makes — from the design of the IRB study to the way we report preliminary findings. These aren't aspirational values. They're constraints that shape the work.

01
We report what we know — not what we expect to find

Every outcome claim on this site is drawn from actual pilot data or active IRB research, not projected from internal estimates or aspirational targets. Where findings are preliminary — specifically VLAP signal accuracy — that is stated explicitly, with the caveat that results are pending peer-reviewed publication. We don't report IRB study findings before the study is complete.

02
Community engagement is design, not consultation

The VLAP training corpus was built in partnership with the communities whose language it reads — not assembled from web-scraped data and checked with communities afterward. Vocabulary candidates were community-sourced. Annotation protocols were reviewed by clinicians with documented community competency. Research priorities are informed by community needs. This is the structural difference between studying a community and studying with it.

03
Bias monitoring is an operational gate, not a post-hoc audit

False positive and false negative rates are disaggregated by demographic subgroup throughout model development — not checked after a model version is deployed. A model version that meets aggregate accuracy targets but fails subgroup parity thresholds across BIPOC, LGBTQ+, or first-generation subgroups is not deployed. This standard is applied to the IRB validation study as a primary research outcome, not a secondary analysis.

04
IRB oversight applies to every human subjects research activity

All research involving human subjects data — including the University of Maryland validation study and any future studies using Vasl deployment data — operates under IRB approval with informed consent, data privacy protection, and ongoing compliance monitoring. Institutional oversight is a minimum standard, not a credential for marketing purposes. The full IRB study protocol is available to qualified institutional evaluators under NDA.

Chapter 04 — Publication Status

In progress.
Not yet published.

Vasl Health does not currently have peer-reviewed publications. The IRB study with the University of Maryland is the primary vehicle for the first peer-reviewed publication. Here is what is in progress and when it is expected.

In Progress — Pending Publication
VLAP Cultural Signal Detection Validation — University of Maryland IRB Study

The primary planned publication is the peer-reviewed results of the active University of Maryland IRB study — validating CulturalBERT-VLAP's signal detection accuracy against clinician-adjudicated ground truth in deployed pilot cohorts. The study uses production data from live Vasl deployments across BIPOC, LGBTQ+, and first-generation youth populations. Results will be submitted to a peer-reviewed journal upon study completion.

this together?

We are actively interested in research partnerships with academic institutions, health systems, and community organizations working on behavioral health equity, culturally-responsive AI, and clinical NLP. We bring the platform infrastructure, production deployment data, and community relationships. We're looking for partners who bring research rigor, clinical expertise, and institutional oversight.
