Pierre De Meyts (born 1944) is a Belgian physician and biochemist known for his research on fine chemical and kinetic aspects of ligand-receptor interaction, subunit assembly, and specific metabolic (as well as mitogenic) effects of hormones typically causing receptor tyrosine kinase activation such as insulin and insulin-like growth factors (IGFs).

During this NIH period, De Meyts became a prominent member of the research group led by Jesse Roth, studying insulin receptors, and authoring a dozen original papers in duly indexed journals.

During this period in Denmark until 2011 De Meyts simultaneously held academic posts as adjunct professor of experimental endocrinology (2000-2005) and guest lecturer (2007-2011) at the University of Copenhagen Faculty of Health Sciences.

[10] De Meyts began his research career while a medical student at the University of Liège, collaborating with mentors such as Jean Lecomte and Annie Cession-Fossion in studies of the vascular actions of sympathomimetics.

[11][12] During a three-year visit to NIH starting in 1973, De Meyts got involved in what -by far- would become his major research fields: hormone-receptor interaction of peptide hormones and the study of the physiopathogenesis of diabetes.
