Research Program

Cell-type-resolved extracellular vesicles and multi-omics for blood-based measurement of neurodegeneration.

  • Multiple sclerosis
  • ALS
  • CNS biology
  • Multi-omic interpretation
The central thesis

Cell-type-resolved extracellular vesicle signals can make neurodegeneration measurable, interpretable, and eventually actionable.

Can molecular cargo from defined CNS-cell-derived extracellular vesicles provide a reproducible blood-based view of disease progression—and identify mechanisms that can be tested experimentally?

The program focuses first on multiple sclerosis and amyotrophic lateral sclerosis, with a broader CNS biology agenda that can extend across neuroinflammatory and neurodegenerative disease.

Measure · Map · Functionally Validate

The 3M framework is a sequence: establish that an EV signal is measurable, connect it to biology and patient trajectory, then test candidate mechanisms under controlled conditions.

From sensing systems to a CNS biomarker program

The program separates established platform work from current disease-focused studies and future independent directions. The common thread is measurement: make a complex biological signal cleaner, connect it to context, and create a controlled experiment that can challenge the interpretation.

EV measurement

Built cleaner ways to recover vesicle signals

I developed a photosensitive lipid-nanoprobe platform for rapid, size-selective enrichment of synthetic and extracellular vesicles. That work links materials design to the first translational question: can the biological fraction be recovered cleanly enough to interpret?

CNS biology

Moved EV analysis toward cell-type-resolved disease biology

At Yale, my current work studies astrocyte-enriched plasma small EV miRNA and mRNA programs in multiple sclerosis and related neuroimmune and neurodegenerative settings, including ALS, long COVID, NMOSD, remyelination, and aging.

Research-stage prognostic and monitoring candidates; not a validated diagnostic test
Functional platforms

Connected molecular signals to controlled experiments

Earlier platform work established a native plasma-membrane-on-a-chip system and quantitative secretory-vesicle assays. These systems supply the experimental discipline behind Manipulate: distinguish association from uptake, delivery, pathway engagement, and functional response.

Computation + translation

Built a route from evidence to useful decisions

EVd3x makes multi-omic evidence traceable across pathways, diseases, cell contexts, interactions, and validation hypotheses. Through East Rock Diagnostics, I am translating this measurement logic into Astroscope™, a research-use platform for astrocyte-derived EV analysis.

The computational core

EVd3x is the computational infrastructure for the Map pillar.

EVd3x begins with source-attributed evidence review and grows into a structured learning environment for EV biology. It keeps molecular evidence inspectable while the longer-term program trains interpretable models on curated evidence and longitudinal EV multi-omic cohorts.

This creates a practical route from a candidate cargo list to a reviewable biological hypothesis, then to cohort-aware models for progression, stratification, and rigorously defined diagnostic use cases.

01

Curate claim–evidence units

Build expert-reviewed records that specify the strongest supported EV claim, its source publication, preparation and characterization context, assay, biological setting, and missing prerequisites. Contradictory and context-mismatched records become essential training examples rather than noise to hide.

02

Train EV-specific evidence models

Use the curated graph to train models that classify supported claim boundaries, identify independent versus repeated evidence, surface missing verification steps, and explain why a candidate should advance, remain uncertain, or be rejected.

03

Link models to longitudinal multi-omic cohorts

Connect analytically controlled EV miRNA, mRNA, protein, lipid, imaging, and clinical data to prespecified outcomes such as progression or treatment response. Cohort-aware model development will prioritize interpretable features, leakage control, and locked external evaluation.

04

Validate a defined clinical use

Only after the target population, specimen, outcome, threshold, and independent performance are established can a model be evaluated for a diagnostic, prognostic, monitoring, or predictive context of use.

What the program is doing now

The vision is grounded in a set of linked projects rather than a single assay or model. Each one answers a different part of the translation problem, and each has an explicit evidence boundary.

CNS biomarker discovery

Make glial biology visible in blood

The current translational work studies cell-type-enriched EV cargo in secondary progressive multiple sclerosis, ALS, long COVID, NMOSD, remyelination, and aging. The immediate objective is to identify reproducible miRNA and mRNA programs associated with disease state or progression in defined research populations.

Research-stage prognostic and monitoring candidates; diagnostic use requires additional population, threshold, and validation evidence.
Assay development

Build the Astroscope measurement chain

Astroscope connects a small plasma sample to astrocyte-derived exosome enrichment, targeted cargo readouts, quality control, and a locked research-use report. The engineering question is whether the full chain can remain analytically disciplined as it moves toward clinical-trial and biopharma workflows.

RUO development with technical-validation and assay-development support.
Computational biology

Use interpretable models to preserve the evidence trail

EVd3x is a source-attributed workspace for interpreting EV multi-omic evidence. It links cargo evidence to pathways, diseases, cell contexts, interactions, and validation hypotheses, creating a reproducible route from an observed molecular feature to a biological explanation and a next experiment.

Live research platform with a roadmap toward EV-specific evidence and cohort models.
Mechanistic platform science

Test whether cargo can change cell state

Earlier work on membrane-on-a-chip systems, secretory-vesicle assays, lipid nanoprobes, and engineered vesicle mimics supplies the functional vocabulary for the third M. These platforms help separate association, uptake, delivery, pathway engagement, and reproducible response.

Preclinical mechanism and functional-gate development.

Biomarker development is a context-of-use problem

A model cannot become a clinical claim by accuracy alone. Each research program specifies its population, specimen, intended use, evidence stage, and the next validation required. This keeps terms such as prognostic, monitoring, and diagnostic precise.

East Rock Diagnostics: from assay to use case

As Co-Founder and Scientific Lead, I help translate the research program into a platform that can be evaluated by clinical and biopharma partners. Astroscope™is designed to enrich astrocyte-derived exosomes from a small plasma sample, then quantify targeted protein, miRNA, and lipid cargo as biologically grounded CNS signatures.

The company is developing a research-use platform for evaluating astrocyte-derived EV measurements with clinical and biopharma collaborators. Its role here is translational assay development, not a claim that the platform is a validated clinical diagnostic.
