William Campbell (scientist)

William Campbell is an American scientist renowned for his pioneering work in parasitology and infectious diseases. He received the Nobel Prize in Physiology or Medicine in 2015, shared with Satoshi Omura, for discovering avermectins—potent drugs derived from a soil-dwelling microorganism. These drugs revolutionized the treatment of parasitic infections like river blindness and elephantiasis, significantly reducing suffering and disease burden in affected populations. Campbell's research has had a profound impact on global health, transforming how parasitic diseases are controlled and demonstrating the importance of natural compounds in medical advancements.
