Professor of Informatics • Founder, ChatifyIT • AI Entrepreneur
I hold advanced degrees from Columbia University and the University of Pennsylvania. My research focuses on analyzing authority signals across AI platforms.
Research and business are two sides of the same coin. I'm nosy, and that nosiness has led me to discover my greatest loves: entrepreneurship and research — both of which are now on steroids with AI. It's time you discover how AI can transform your life.
The Authority Signals Framework™
Understanding which sources AI systems prioritize requires asking four critical questions
Institutional Affiliation
"Who published it?"
Institutional Affiliation answers "Who published it?" by categorizing sources by organization type, highlighting that different organizational contexts (government agencies, medical institutions, academic institutions, commercial platforms, professional practices) carry varying levels of inherent institutional credibility in health information contexts.
Author Credentials
"Who wrote it?"
Author Credentials answers "Who wrote it?" by capturing individual-level expertise through professional degrees, certifications, and medical specialization. Variables range from no author attribution to visible medical credentials with specialty identification.
Quality Assurance
"How was it vetted?"
Quality Assurance answers "How was it vetted?" by documenting editorial processes and evidence standards through presence of medical review statements, content recency, and citation of supporting references.
Digital Authority
"How does AI find it?"
Digital Authority answers "How does AI find it?" by quantifying web-based credibility signals including Moz Page Authority, Domain Authority, spam scores, schema markup implementation, and content length.
