Katherine J. Wu is a scientist, writer, and science writer, not necessarily in that order. She recently earned a Ph.D. from Harvard University, where she studied how bacteria deal with stress so that she could one day learn to do the same. Now, she is a Digital Editor for NOVA at WGBH in Boston. She formerly served as a 2018 AAAS Mass Media Fellow at Smithsonian magazine and as Co-Director of Science in the News, a graduate student organization dedicated to communicating science to the general public. In her spare time, she serves as a heat-generating pillow for her cats and continues her quest to find the authentic tacos east of the Mississippi.
