Who is DR. WHO? Him.

Behold one of the many works of the (or a) real Dr. WHO:

W.H.O. Ernst, 1996. “Bioavailability of heavy metals and decontamination of soils by plants,” Applied Geochemistry, vol. 11, nos. 1–2, January–March 1996, pp. 163–167. Dr. Who is or was at the Department of Ecology and Ecotoxicology, Faculty of Biology, Vrije Universiteit Amsterdam, The Netherlands.


He is in fact Prof. Dr. W.H.O. Ernst.
