Independent scientific judgment
Know whether the science can bear the weight of the decision.
I help investors, founders, institutions, and decision-makers evaluate science-heavy claims before they commit capital, credibility, or organizational support.
40+ peer-reviewed articlesAcross cognitive science, neuroscience, aging, and experience-related neuroplasticity
Published in leading journalsIncluding PNAS, NeuroImage, Cognition, and Developmental Science
Methodological depthBehavioral science, EEG/ERP, neuroimaging, multivariate analysis, and evidence synthesis

Best-fit domains
Deepest value where the claim depends on cognition, the brain, or behavior.
I can review work outside these areas when the core question is methodological, but these are the domains in which my scientific background is most directly relevant.
Neurotechnology
Cognitive assessment
Brain health and aging
Learning and language
Behavioral and digital products
Research methods and evidence claims

The standard
Not a persuasive narrative. A defensible analysis.
The review explicitly separates established findings, inference, assumption, uncertainty, and speculation. Weaknesses are stated directly, without manufacturing certainty where the evidence does not support it.
Simple process
From materials to a usable decision memo.
Send the question and materials
Explain what is being evaluated, what decision it informs, and what evidence is currently available.
Confirm scope and fixed fee
I identify the appropriate depth, exclusions, timeline, and deliverable before work begins.
Receive the written review
The memo prioritizes decision-relevant strengths, limitations, uncertainty, and implications.
Optional debrief
A focused discussion can clarify findings and the questions that should be asked next.

Sample scientific review memo
See how a client-facing memo states what the evidence supports, what it does not establish, which risks matter, and what evidence would change the conclusion.
