As a chemical engineer, Hadley Sikes loves studying complex systems such as networks of chemical reactions. But in her work designing practical devices for diagnostics and other applications, she embraces simplicity. Sikes, an associate professor who recently earned tenure in MIT’s Department of Chemical Engineering, devotes much of her lab’s effort to devising inexpensive, highly sensitive tests for diseases such as malaria, tuberculosis, and cancer. Making these tests easy to use is key to their success, she says. “In the products that we want to widely disseminate, our idea is…
