Julie Rayes is an Associate Professor in Cardiovascular sciences. She holds a British Heart Foundation Intermediate Fellowship. She is interested in understanding the immunoregulatory functions of platelets beyond haemostasis. Her team focuses on the crosstalk between platelets, immune and endothelial cells to identify targets that limit thromboinflammation during infections and sterile inflammation.

Qualifications

  • PhD in biology and pharmacology of haemostasis and vessels (Denis Diderot university-Paris VII)
  • MA in biology and pharmacology of haemostasis and vessels (Denis Diderot university-Paris VII)

Teaching

Project supervision

  • Biomedical Science BSc
