Biochemists study chemical processes which occur within living organisms. They explore the chemistry of biology: the molecules in plants and animals and the ways they behave. Microbiologist Luke Moe, who did his doctorate in biochemistry at the University of Wisconsin, studies the ways enzymes within tiny creatures interact with chemicals. Chemist and Cancer Researcher Eugene DeSombre’s research explored the role the hormone estrogen plays in breast cancer and identified ways to figure out which cancers would respond to estrogen-related treatments.
