For five decades, Catherine Fenselau has been at the forefront of the field of biomedical mass spectrometry, which she helped shape as a scholar, educator, and mentor. Her pioneering work spanned from early applications of stable isotope labeling to elucidate fragmentation mechanisms and drug metabolism, to the development of mass spectrometric approaches for microorganism detection, to the application of quantitative proteomics to study drug resistance in cancer. This Special Issue is a celebration of her distinguished career by a handful of alumni, who represent only a small sample of the large number of investigators that she inspired to perform research in this field. The breadth of the themes covered in these contributions provide a small glimpse of her broad influence on the field, which will continue to be felt for years to come.
