Yoon Chang

Seokyoon “Yoon” Chang brings mathematical expertise to studies of the evolution of virulence and vector behavior. He was undaunted as he captured amazing complexities of host-parasite interactions in his mathematical models as an undergraduate. We’re so glad that he joined us in 2022, and we look forward to his graduate school adventures!
