Blood coagulation is an example of time-evolving, heterotypic deposition/aggregation/fragmentation of reactive cells under flow which in turn trigger the polymerization of the fibrinogen monomer. Our laboratory is also interested in inflammation-coagulation crosstalk. These studies have investigated:

  • Neutrophil proteases as triggers of thrombosis
  • Factor VIIa function on platelets
  • High throughput phenotyping of human blood
  • Substrate mapping of coagulation proteases
  • Controlled patterned surfaces of collagen and lipidated tissue factor
  • Clot stability and fragmentation
