Katherine Donovan is a Lead Scientist in the Fischer Lab where she works on the development of molecular-glues and PROTAC molecules for targeted protein degradation. After joining the Fischer Lab as a Postdoc she developed an interest in proteomics as a specialized technology for quantifying protein-level expression changes in response to various perturbations. Katherine set up and led proteomics teams focused on degrader screening and target identification in the Fischer Lab as well as in the Center for Protein Degradation. She has used proteomics technology to identify the degradation targets of many molecules including the identification of SALL4 as the protein likely underlying the teratogenicity of thalidomide. Katherine led a large effort to map the degradable kinome and now to aid her quest to map the degradable proteome she has recently started a public degradation proteomics initiative which provides free target mapping of degraders.
