Specialized doctors worldwide

Who conducts research into chronic lymphocytic leukemia? Everyone listed here comes from a public registry: as principal investigator of a study at ClinicalTrials.gov, or as last author of publications in PubMed. These are two different things, so we list them in two columns side by side instead of combining them into a single figure.

Where these doctors work
Click or point to a dot to see who works there. 25 of the 69 doctors are on the map — we only place those who work at an institute whose city we know, and we don't guess the rest.

This is not a referral and not a judgment on care. We know nothing about how these people treat, whether they accept patients, or how to reach them. We do not display contact details. If you want a second opinion or a referral, go through your own specialist.
