While becoming the mother of two, she did multiple productive postdoctoral fellowships at University of Michigan studying mismatch repair with ovarian cancer, apoptosis, cellular signal transduction, enzymology and finally host/pathogen interactions. She is recognized for her elucidation of novel biochemical mechanisms that bacterial effectors use to modify host proteins including Ser/Thr acetylation and AMPylation. The repertoire of tools she used to decipher these novel activities allowed her to continue studies on metazoan AMPylation in model organisms, including flies and mice, where her lab ultimately created a pre-clinical murine model for neonatal diabetes that is caused by an analogous mutation in AMPylation machinery found in humans. Her lab continues to discover new biology and signaling pathways, including transertion, from bacterial pathogens. In 2001, she joined the faculty in the Department of Molecular Biology at UT Southwestern Medical Center where she is currently a professor. In 2015, Orth became an Investigator for the Howard Hughes Medical Institute. Orth has many awards including the Arnold and Mabel Beckman Young Investigator Award, Burroughs Wellcome Investigator in Pathogenesis of Infectious Disease and Welch Foundation Norman Hackerman Award in Chemical Science. In 2018, she received the ASBMB Merck Award (2018) and wrote a solicited, personal reflection on her path in science for the Journal of Biological Chemistry to provide tools for younger scientists. Orth is a member of the American Academy of Microbiology, The Academy of Medicine, Engineering and Science of Texas, American Association for the Advancement of Science, and of the National Academy of Sciences.
