A cancer diagnosis can be devastating. And the chemotherapy that often follows can be particularly rigorous. The American Cancer Society projects that 2.1 million people in the United States will be diagnosed with cancer in 2026—but researchers are making major advances in cancer treatment and patient survival.

Ziyang Zhang is a chemist and 2023 Pew-Stewart Scholar for Cancer Research who leads cutting-edge studies on reducing the negative effects of chemotherapy on cancer patients. In his lab at the University of California, Berkeley, he and his team are producing new tools at the chemical level that will help to develop more effective therapies to target cancer mutations and avoid damage to healthy cells.
