Uncontrolled internal bleeding is one of the leading causes of preventable death after trauma. Harvard Griffin GSAS and Harvard SEAS bioengineering PhD candidate Maithili Joshi has developed a groundbreaking treatment for these wounds: an injectable, self-assembling peptide that rapidly targets internal bleeding, binds to platelets, and accelerates clotting—without affecting normal blood function. Demonstrated to reduce blood loss by up to 90% in preclinical models, this innovation could redefine emergency trauma care by stabilizing patients when every second counts.
