KOL Finder
Name a therapeutic area, an indication, a drug, a company or an institution and get the key opinion leaders in it: the physicians and researchers who run the registered trials, hold the NIH grants, publish the papers and report the industry payments. The search and the first profile are free, with no account.
Plain English works: the search reads the phrase against the directory’s own vocabulary and lands on the matching filters, which stay visible in the address bar.
What it searches
771,365 physician and researcher profiles, 2,507 of them enriched with itemized records, every one assembled from the public record and matched to the right person before it is published. The sources are federal registries and open scholarly indexes: NPPES, ClinicalTrials.gov, NIH RePORTER, CMS Open Payments, OpenAlex and PubMed. Each number on a profile names the source it came from.
How results are ranked
A search for one indication lists the people most active in it first, by their papers and registered trials in that indication, so a myeloma search leads with myeloma investigators and not with the most-cited oncologist who mentioned it once. A broader search orders by citations on OpenAlex. Any list re-sorts by publications, h-index, trials, recent activity or rising activity, and filters by region, institution, company, specialty, society role and more.
What a row shows, and what it never shows
Identifiers, counts, years and the sources behind them. Never scraped emails or phone numbers, never prescription claims data, and never a judgment of anyone’s influence on a public page. Ranking tiers are an interpretation and stay behind an account, on profiles a user has opened.
What you get on each profile
The right person
Every US profile is anchored on an NPI from the federal NPPES registry, and the research identity on ORCID where it is confirmed. A namesake is shown with specialty and place before anyone opens it.
Trials
Registered studies from ClinicalTrials.gov with the person's role, the phase, the status and the sponsor, so an investigator list reads from the registry and not from a brochure.
Grants and payments
NIH projects with fiscal year and award amount from NIH RePORTER, and industry payments by company and program year from CMS Open Payments. Payments are reported facts; the page never interprets them.
Publications and congresses
Publication and citation counts from OpenAlex and PubMed, the recent papers, and congress abstracts where the record carries them, with an Emerging flag on profiles whose recent activity is rising.
Find KOLs by therapeutic area
Each area has its own page with the registered trials, NIH awards and reported payments of the people in it, cited and dated, and the institutions where the work is.
