Researcher | Research Overview

Dr. Michelson's research group, the Center for Platelet Research Studies (CPRS), is an internationally recognized, multidisciplinary center for the study of platelets by state-of-the-art methods. The CPRS is an integrated research group that performs basic bench research, translational research, and clinical research on platelets and related aspects of hemostasis and thrombosis.

A particular focus of research in the CPRS is antiplatelet therapy, including characterization of:

  • Novel molecules and mechanisms for therapeutic platelet inhibition
  • The effects of antiplatelet agents on coagulation and inflammation
  • The relationship between the degree of inhibition of platelet function and clinical outcomes (thrombosis vs. hemorrhage)
  • The use of in vitro platelet function tests to guide antiplatelet therapy in order to obtain better clinical outcomes
  • The relationship of platelet function to clinical outcomes in immune thrombocytopenia (ITP)

Researcher | Research Background

Dr. Michelson received his medical degree with honors from the University of Adelaide, Australia and was a Fulbright Scholar at Harvard Medical School. Dr. Michelson is the editor of the textbook "Platelets" (Elsevier/Academic Press). The first edition of "Platelets", published in 2002, was the winner of the Best Book in Medical Science Award from the Association of American Publishers. The 64-chapter, 1300-page third edition was published in 2012.
